Polyvinylidene fluoride (PVDF) belongs to the group of fluorine-containing thermoplastics whose most well-known member is Teflon® (PTFE) and typically exhibit low surface energy and poor bonding characteristics. Plasma treatment significantly increases the surface energy of PVDF resulting in much elevated bond strengths.
