Plasma Treatment of PTFE

Henniker announce the release of technology pages on the plasma treatment of PTFE. PTFE is a chemically inert and highly hydrophobic fluoropolymer due to the high electronegativity of fluorine. It is not readily modified by standard plasma processes but the may be altered to render the surface hydrophilic by the use of hydrogen plasma,. Read more on the processes involved here.

Q
What is a Plasma?
A

Solid, liquid and gas are the three states of matter we are all familiar with. We can move between the states by adding or removing energy (e.g. heating/cooling). If we continue to add enough energy (for a plasma, we add electrical energy), gas molecules will become ionised (lose one or more electrons) and so carry a net positive charge. If enough molecules are ionised to effect the overall electrical characteristics of the gas the result is called a plasma. Plasmas are therefore, quite rightly, often referred to as the fourth state of matter.

A plasma contains positive ions, electrons, neutral gas atoms or molecules, UV light and also excited gas atoms and molecules, which can carry a large amount of internal energy (plasmas glow because light is emitted as these excited neutral particles relax to a lower energy state). All of these species can and do interact with any surface placed in contact with the plasma. By choosing the gas mixture, power and other conditions we can quite precisely tune, or specify, the effects of the plasma upon the surface.

Q
What does plasma treatment do?
A

Plasma treatment modifies the surface of an object. It doesn’t affect the object in any other way and doesn’t change the bulk of the material at all. We can ‘tune’ the plasma to change the adhesion characteristics of the surface. We can make the surface easier to bond, print, glue etc. We can also introduce a range of other surface properties such as liquid repellency or low friction.
