Making the non-stick stick

Teflon, polytetrafluoroethylene, PTFE is renowned for its non-stick properties. Now, researchers at Osaka University Japan have found a way to make PTFE stick to other materials more effectively than before providing a way to make the slipperiest coatings possible even on materials such as rubber. “With our plasma treatment, we improved the adhesion of the PTFE to some extent, but it was only when we combined this with extra heating of the PTFE that we saw it strongly adhering to rubber," explains team member Yuji Ohkubo. Kazuya Yamamura adds that, “In industrial processes, adding a heater to a plasma chamber is much easier than trying to adjust the temperature through the plasma power. We hope this new technique allows PTFE to be used in new ways that just weren’t possible or practical before.”
