Non-stick performance of polymethylsilsesquioxane thin films synthesized by sol–gel spray coating

Abstract

The non-stick properties of polymethylsilsesquioxane (PMSQ) sol–gel films fabricated via spray coating were investigated in this study. A high non-stick performance was achieved by preparing sols under strongly acidic conditions. Infrared absorption spectroscopy analyses suggested that these conditions promoted the formation of highly symmetric Si–O–Si structures, which contributed to the enhanced non-stick behavior. The PMSQ films proposed in this study are transparent and fluorine-free, rendering them suitable for applications such as cooktops.
