(Summary description)(a) polytetrafluoroethylene/polydimethylsiloxane /Cu, (b) polytetrafluoroethylene/polydimethylsiloxane /SUS430, (c) polytetrafluoroethylene/polydimethylsiloxane/glass. Polydimethylsiloxane treated with plasma technology can be used as a substitute for strong adhesives to adhere fluoropolymers to other types of materials. Polymer has the characteristics of light weight, high strength and good stability, and has become an essential material in modern life. However, most polymers do not naturally adhere to other materials. Therefore, it needs to be surface treated with adhesive or corrosive chemical treatment. This has caused great trouble in the food and medical fields, where pollution must be strictly controlled. It is urgent to realize clean bonding of industrial polymers. According to Scientific Report, a team of researchers at Osaka University in Japan has found a breakthrough. They developed a plasma treatment that not only made vulcanized rubber and polytetrafluoroethylene (PTFE) adhere to each other, but also to other materials. "PTFE is sprayed by a helium plasma at 200 ° C and sticks to unvulcanized rubber," says Yuji Ohkubo, author of the paper. This problem has been solved in our earlier research. But vulcanized rubber is more challenging. To this end, we have developed a novel plasma treatment for vulcanized silicone rubber that is tightly bound to PTFE. The silicone rubber mentioned by Nkubo Yuji mainly refers to polydimethylsiloxane (PDMS). The key to the adhesion of PTFE is thermo-assisted plasma treatment. For PDMS, the trick is to bombish the surface with a plasma jet, breaking the silicon-carbon bonds on the surface and converting them into silanols. The newly produced silanols are more surface active and can bind to PTFE. Then, under high pressure conditions, silanols form hydrogen bonds with oxygen-containing functional groups in the treated PTFE, thus forming a strong bonding effect. By bonding the two materials together, the new material combines the chemical resistance, scale resistance and slip resistance of PTFE with the elasticity of silicone rubber. PTFE can be replaced with perfluorane, which is more transparent, if the material transparency is required. More significantly, when the back of the PDMS is also treated with plasma technology, it can bond with copper or even glass. Plasma-treated PDMS act like double-sided tape, allowing the polymer to adhere "cleanly" to other material surfaces. Co-author Katsuyoshi Endo explained: "The new adhesion effect could make PTFE and PDMS more versatile in medical and food technologies. We hope that this non-binder bonding technology will broaden the range of polymer applications in high-tech fields."
