WebFluoropolymers by nature are quite inert to chemical reactions and thermal degradation. They have a low surface energy and are generally incompatible with other polymers. Microscopic examination of a polyethylene (PE) that contains PPA, reveals discrete micron-sized droplet shaped particles of the fluoropolymer [1]. WebWettability of those fluoropolymers measured both before and after AP helium plasma treatment is shown in Figure 2. Contact angles with water of all fluoropolymers decreased to about 30° after the treatment. The results show that AP helium plasma treatment was an effective method to improve the wettability of most fluoropolymers. how to scan a multiple page document to pdf
