• "thiol-ene" click
• Amphiphilic block copolymers
• Fluoroalkyl acrylate
• Oleophobic/hydrophilic

Firstly, macro chain transfer agents CTA-FnA (n=1, 3, 6, 8) were synthesized by reversible addition-fragmentation transfer (RAFT) polymerization. Hexylamine was used to reduce disulfide ester to active thiol (-SH) efficiently. Next, allylpolyethyleneglycol (APEG1200) was connected to a PFnA block with a terminal -SH group via "thiol-ene" click reaction. Then the set of amphiphilic block copolymers of poly(fluoroalkyl acrylate)-block-allylpolyethyleneglycol [PFnA-b-APEG1200 (n=1, 3, 6, 8)] were obtained successfully. Employing monomers with various fluoroalkyl numbers can alter the composition of the constituent blocks and the length of the side groups, which facilitates to regulate the surface wettability of the as-prepared coatings.
