丙烯酸和胶原蛋白对PET的表面改性研究进展

聚对苯二甲酸乙二醇酯（PET）具有良好的物理化学性能，作为植入性生物材料具有较好的应用前景，但是其疏水性和生物惰性，制约着材料在医学上的应用，因此对材料进行改性以提高材料的生物相容性尤为重要。文章首先简述了表面改性尤其是PET表面改性的必要性；其次，论述了国内外用丙烯酸对PET进行改性的研究现状；接着论述了用胶原蛋白对医用高分子材料进行改性处理以提高材料生物相容性的研究现状；最后，指出了PET改性材料的应用前景。

Surface modification of PET by acrylic acid and collagen

Poly (ethylene terephthalate)（PET）has good physical and chemical properties and has better application prospects as the medical polymer material. But the poor absorbency and biocompatibility of PET restrict the application in biomedical areas. So it is important to improve the biocompatibility of PET by surface modification. Firstly, this paper expounds the necessity of surface modification especially PET surface modification; then it states the development of acrylic acid used for modification of PET; furthermore, it discusses the surface modification of polyester by collagen based on biocompatibility. Finally, it points out the development prospects of the modified polyester.
