Effects of He and Ar Heat-Assisted Plasma Treatments on the Adhesion Properties of Polytetrafluoroethylene (PTFE)

“…UV irradiation [ 1 , 2 , 3 ], electron beam (EB) irradiation [ 4 , 5 ], and synchrotron irradiation [ 6 ] have been used to improve the adhesion properties of PTFE; however, these methods concern a deep modification depth and thus were excluded from the present study. Although various surface modification methods for polymers such as corrosive solution immersion treatment [ 7 ], plasma treatment [ 8 , 9 , 10 , 11 ], and ion irradiation [ 12 , 13 , 14 ] have been developed, the most effective methods for PTFE modification include Na-containing solution immersion treatment (Na treatment) [ 15 , 16 , 17 ], surface graft polymerization after plasma treatment [ 18 , 19 , 20 ], surface graft polymerization during plasma treatment [ 21 , 22 , 23 ], and heat-assisted plasma (HAP) treatment [ 24 ]. Conventional plasma treatments have given a low effect of improvement in the adhesion property for PTFE [ 8 , 9 , 10 , 11 ]; however, Ohkubo et al found that heating during plasma treatment positively affected the adhesion property of PTFE.…”

Surface modification of polytetrafluoroethylene film by argon cold atmospheric pressure plasmas for enhancing bonding with graphene‐filled polyimide adhesives

“…The air CAPPs have been used to improve the wettability (hydrophilicity) of polymers such as polyethylene (PE) and polypropylene (PP), [3,4] silicone, [4] PE-boron composites and polyamide, [5,6] and to enhance the adhesion of polymers, such as PP with polyurethane (PU) adhesive, [7] glass fiber reinforced epoxy and polyester with PU adhesive, [8] poly(ethylene terephthalate) and poly(ether-ether ketone) with epoxy and urethane methacrylate ester adhesives, [9] and PTFE with acrylic and epoxy adhesives. [10] However, the air CAPPs-treated PTFE film has poor adhesive strength with PU adhesive. [10] This study attempts to augment the adhesion of PTFE films with polyimide (PI) adhesives by argon (Ar) gases-CAPPs.…”

Effect of UV/ozone treatment on the wettability and adhesion of polymeric systems

“…Previous studies investigated the effect of different parameters on the wettability of polymers. For example, it is found that Teflon wettability increased with higher surface roughness, changed mechanically using grit blasting or chemically using NaOH and HNO3/KMnO4 solutions [15] [16]. This was not the case for plasma polymer thin films (pp-GT) and Na-treated Teflon [17] [15].…”
