Plasma Technology within UK Manufacturing
Henniker’s home-grown plasma treatment technology
This month’s Materials & Manufacturing Technologies’ magazine includes a focus on our home-grown UK manufactured plasma technology. The article includes an introduction to plasma treatment within the UK manufacturing field. To read the full article either scroll below or click the link to be re-directed to the original publication.
Plasma in the UK
Plasma treatment has become a very broad field as the number of materials and range of surface properties has increased. Plasmas are routinely used to produce ultra-clean surfaces and to activate surfaces prior to bonding, a technique which is on the increase in motorsports for example where improved mechanical properties are achieved by through increased lap-shear strength.
Plasmas can also impart specific functionality onto surfaces where they are delivering benefits to medical fabrications such as point of care devices requiring immediately wettable surfaces that can only be achieved by depositing nano-scale plasma polymers.
Plasma have a number of unique properties that have led to such widespread application. They are able to treat complex 3D objects, are environmentally friendly and can deliver very specific and uniquely tailored surface property modifications at very low temperatures.
The feedstock is typically made up of only one or two substances, helping to minimise or even completely eradicate, residues that could later become the source of problems.
In its UK development and manufacturing headquarters, Henniker combines state of the art plasma treatment equipment with comprehensive surface testing facilities. Highly trained and dedicated staff with years of practical experience in plasma and surface testing techniques are on hand to assist new and existing clients with free proof of concept trials, application support and process development services.
Henniker invited to discuss future of plasma treatment for leading composites manufacturing magazine
Surface effects – Composites In Manufacturing Magazine
Composites in Manufacturing magazine recently contacted Henniker Plasma to discuss the growing role of plasma technology within UK composites manufacturing.
The full article and link to the original publication appear below.

Traditional methods to clean and activate composite surfaces can be time-consuming and imprecise – hence automated techniques are coming to the fore.
Blasting a material surface with plasma may sound like something out of James Bond – requiring at least a particle accelerator – but nothing is further from the truth. “Plasma is not even hot – it’s only slightly above ambient temperature,” says Terry Whitmore, managing director of Henniker Plasma, which supplies a range of plasma treatment devices.
The technique is used to prepare many material surfaces – including composites – for processes such as bonding or painting. There are two variants: vacuum plasma, which encases components – normally large ones – in a chamber and treats their entire surface; and atmospheric plasma, which is used to treat smaller components – or portions of a large part.
“Plasma treatment does two things,” continues Whitmore. “It cleans the surface of organic contaminants, and it activates the surface – to make it more likely to bond.”
The charged ions in the plasma first break down organic compounds such as grease. The remnants are then removed in the gas phase, leaving the surface pristine. Next, it raises the surface energy, which ‘activates’ it, and promotes the adhesion process.
Adhesion has become a more important property for composites, as it allows them to be joined to metals to form ‘hybrid’ parts – which are well established in motorsports, and becoming increasingly common in the automotive industry.
Composite surfaces are traditionally prepared for adhesion by roughening them by hand – or ‘hand sanding’ – using a piece of Emery paper. “The difficulty is to do it consistently across the whole part,” states Whitmore.
He reports seeing instructions in an aerospace lab to “lightly sand the part” – in preparation for bonding cable harnesses to the fuselage. This is open to wide interpretation, he says – meaning that an automated technique like plasma treatment ensures a more consistent surface activation.
Henniker recently used the technique to improve the mechanical properties of a natural fibre composite – by applying the principle at a microscopic scale.

Once composites have been surface-treated, they can be bonded more effectively
It was a partner in UK-Biocomp – a project within the Composites Innovation Cluster – which has developed a family of reinforcement materials based on aligned natural flax fibres. They can be supplied as tapes in widths up to 170mm, or as full-width non-crimp fabrics.
“Ordinarily, composites based on natural fibres like jute or flax have lower mechanical properties than conventional materials,” comments Whitmore.
However, their low weight and low environmental impact made them a potentially attractive material for industries such as automotive.
“Plasma treatment helped to improve adhesion between the resin and the matrix,” he adds.
Whitmore is confident that this type of value-added application is the future for plasma treatment. He says the Henniker has already looked at applying polymer films onto material surfaces.
“If we use a polymer with liquid repellent properties, we can apply it to a surface at the microscale without affecting bulk properties,” he says.
Henniker is working with several companies to apply this kind of technology – with surfaces including hydrophilic and biocompatible.

Surface activation and cleaning for modification of biomaterials

Activation of Surfaces for Biomedical Applications
Biomaterials are any material, surface or matter that forms a boundary to, and interacts with a biological system and as such they are frequently developed, used and adapted for novel medical applications. Our plasma treatment systems play a key enabling role in this exciting field of research, as discussed below by Dr. Julien Gautrot. Bio-interfaces, the interfaces between proteins, cells or tissues and inert materials, are fascinating systems that play key roles in biological and biomedical applications.
Research in our laboratory focuses on the design of novel biomaterials and methodologies that allow the study of bio-interfaces and their control for applications in cell-based assays, bio-sensors
and regenerative medicine. Our work in the field of biomaterials design is inspired by Nature’s strategies to generate complexity and control function and properties. In particular, we are interested in novel synthetic tools and methodologies allowing the use of Nature’s own building blocks, peptide sequences, to confer mechanical, chemical and biological properties to biomaterials. This approach,
well suited for design, is appealing as it makes use of the inherent biological “wiring” that has evolved to control cell and tissue homeostasis: peptide sequences and proteins are the key components that shape biological tissues. In addition, we develop new micro- and nano-patterning techniques to recreate the geometric and hierarchical complexity encountered in cells and tissues (e.g. positioning of organelles, generation of cell polarity and mimicking of tissue architecture and morphogenesis).
Low pressure plasma treatment is a key enabling step for cleaning, preparation, and modification of biomaterial surfaces. The plasma can be used to remove absorbed contaminants and other impurities, producing cleaner and more well-controlled surfaces than with other preparation methods. Plasmas also activate the top most surface layers, rendering the material hydrophilic, which
in turn promotes attachment and adhesion of functional biological species. In essence, plasma treatment can enhance functionality and biocompatibility of biomaterial surfaces. We chose the compact benchtop plasma system from Henniker following a recommendation from a colleague. The technical staff at Henniker were very knowledgeable and understood what we needed from a plasma unit. Communication was great and they dealt with our enquiry efficiently from the start. Key questions that these tools will help us to address are: how do biological, mechanical and chemical properties of bio-materials (whether synthetic or of natural origin) cross-talk to control cell behaviour and in particular stem cell fate decision? How do cells remodel such materials and how does this impact on cell behaviour and tissue formation? Finally, what is the minimum set of rules or properties required to achieve a desired cell or tissue function?
“We needed a low throughput relatively small chamber at a reasonable cost. Your equipment was just right for our type of applications and sample sizes”.
“The technical staff at Henniker were very knowledgeable and understood what we needed from a plasma unit”
