Preparation and antibacterial properties of hydrogel coatings on PPEK
Polyacrylic acid/acrylamide hydrogel coatings were prepared via silver ion catalyzed surface free radical polymerization on the surface with holes of composite materials with holes prepared by incorporation of poly(phthalazinone ether ketone)(PPEK)with silver powder.The structure and properties of hydrogel coatings were characterized by Fourier transform infrared spectroscopy(FTIR),tungsten filament scanning electron microscope(SEM),X-ray photoelectron spectroscopy(XPS).Antibacterial properties and cytocompatibility of hydrogel coatings were investigated.The results show that the adhesion energy between the coating and the base material is increased from 185.83 J/m2 to 926.26 J/m2 after making holes on the surface of PPEK.The antibacterial rate of the coating against E.coli and S.aureus is more than 95%,and there is no cytotoxicity,expanding the application of PPEK in medical and health field.
