摘要

Polydimethylsiloxane (PDMS) is a material that suffers from hydrophobicity recovery. Permanently hydrophilic PDMS surfaces were created using electrostatic self assembly of polyethyleneimine (PEI) and polyacrylic acid (PAA) on top of a hydrolyzed poly(styrenealt- maleic anhydride) (h-PSMA) amphiphilic layer adsorbed on PDMS. The polyelectrolyte multilayers were crosslinked by carbodiimide coupling with subsequent covalent attachment of polyethylene glycol (PEG) chains to the crosslinked polyelectrolyte multilayers (CPEMS) to produce stable, hydrophilic, protein resistant coatings which resisted hydrophobicity recovery in air.
