Short-chain fluorocarbon-based polymeric coating with excellent nonwetting ability against chemical warfare agents

The ongoing concerns and regulations on long-chain fluorinated compounds (C8 or higher) for nonwetting coatings have driven the market to search for sustainable alternative chemistries. In this study, a copolymeric coating containing short-chain fluorinated groups was synthesized to achieve excellent nonwetting ability against hazardous chemical warfare agents (CWAs). A copolymer of 1 H ,1 H ,2 H ,2 H -perfluorooctyl methacrylate (PFOMA) and ethylene glycol dimethacrylate (EGDMA, crosslinker) was directly coated onto a textile fabric via initiated chemical vapor deposition. The p(PFOMA- co -EGDMA) coating shows a rough-textured morphology with a bumpy, raspberry-like structure leading to high contact angles ( water > 150° and dodecane = 113.8°) and a small water shedding angle (
