近几年来,离分子材料的生物医学应用变得日益重要,生物材料的主要决定性因素应具有可接受的生物相容性及较好的物理机械特性,而这些因素又取决于材料本身的合成与接枝,本文作者运用了聚(2-羟基乙基丙烯酸甲酯)(PHEMA)与合成苯乙烯-丁二烯-苯乙烯三块共聚物(SPS)溶剂铸造薄膜,在钴60γ-射线照射下进行接枝。这种接枝共聚物可作IR吸收光谱检查,通过扫描电子显微镜研究它们的形态学,测定接枝程度和SBS,接枝的SBS-g-HEMA及PHEmA的化学特性,为了研究这种材料的生物相容性,而进行了接触角、血液凝固时间的实验,但接枝的程度与浸渍时间、薄
In recent years, the biomedical applications of molecular materials have become increasingly important. The main determinants of biological materials should have acceptable biocompatibility and good physical and mechanical properties, which in turn depend on the synthesis of the materials themselves Grafting, the authors used a poly (2-hydroxyethyl methacrylate) (PHEMA) and synthetic styrene-butadiene-styrene three copolymer (SPS) solvent casting film, cobalt 60γ-ray irradiation Grafting. The graft copolymers were examined by IR absorption spectroscopy and their morphology was investigated by scanning electron microscopy to determine the degree of grafting and the chemical properties of SBS, grafted SBS-g-HEMA and PHEmA. To investigate the effect of Biocompatibility, and the contact angle, blood coagulation time experiments, but the degree of grafting and immersion time, thin
