细胞相容性聚氨酯的合成及其细胞相容性研究
Preparation and Characterization of Cell Compatible Polyurethane
摘要
Abstract
Cell compatible polyurethane(PU) was obtained by surface photo-grafting of 2-hydroxyethyl acrylate(HEA) onto PU membrane surface. Hydroperoxide groups were introduced onto PU membrane surface by photo-oxidization, then the oxidized membrane, immersed previously in monomer solution, was irradiated under UV light. The grafted copolymers were characterized by ATR-FTIR spectra, element spectroscopy for chemical analysis(ESCA) and static water contact angle. The results showed that grafting was confined within the surface layer. Cell compatible study revealed that the attachment and growth of human umbilical vein endothelial(HUVE) cells were improved after HEA grafting. Cells grew faster on the surface with higher oxygen content.关键词
