Abstract
Catechol-bearing polycarbonates (catechol polymers) were prepared comprising i) a catechol repeat unit comprising a side chain catechol group, ii) a cationic repeat unit comprising a side chain cationic group selected from the group consisting of quaternary amine groups, quaternary phosphine groups, and combinations thereof, and iii) a PEG repeat unit comprising a side chain poly(ethylene oxide) group having a degree of polymerization of about 5 to about 30. The catechol polymers form antimicrobial and antifouling films on a variety of substrate surfaces, in particular silicone rubber.
