摘要: Chemical vapour deposition (CVD) is a technique widely applied for the synthesis of thin and highly conformal polymer coatings. The copolymerization poly(1,4-xylylene)s (PPX), with 2-hydroxyethyl methacrylate (HEMA) via CVD revives hardly investigated field PPX chemistry. use alkyl substituted [2.2]paracyclophanes leads to soluble PPX-copolymers. Proof was obtained by correlation both monomer units in 1H,13C-HMBC 2D-NMR spectra. Next, insoluble p(PX-N-co-HEMA) copolymers were synthesized modified commercially available SCS Labcoater. availability hydroxy ester functionality HEMA on film surface indirectly confirmed reduction water contact angles down 65°. Preliminary studies using human umbilical vein endothelial cells (HUVEC) indicate cytocompatibility as deposited films.
