摘　　要：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,但因材料本身的疏水性和生物惰性制约其在医学上的应用,因此需要对材料进行改性以提高材料的生物相容性。简述了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;同时表述了用胶原蛋白对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。Poly（ ethylene terephthalate）（ PET） has good physical and chemical properties and,as an implantable biomaterial,it has bright application prospects. However,the poor absorbency and biological inertia of PET restrict its application in medical area. So it is necessary to improve the biocompatibility of PET by surface modification. This paper expounds the necessity of PET surface modification; then it reviews the current research status of surface modification of PET by acrylic acid both at home and abroad,along with the surface modification of high polymer by collagen for the purpose of improving the polymer＇s biocompatibility. Potential applications of modified PET are presented.
