Perfluoro-tert-butyl alcohol (PFTB), also known as nonafluoro-tert-butanol or 1,1,1,3,3,3-Hexafluoro-2-(trifluoromethyl)-2-propanol, is a critical fluorinated alcohol in advanced fluoropolymer surface modification. Its unique structure—a tertiary alcohol fully substituted with trifluoromethyl groups—imparts exceptional acidity and solubility characteristics
