摘　　要：聚乳酸废料的改性再利用的方法有物理改性、化学改性和物理化学改性.目前,国内外企业主要通过PLA增黏和耐热改性等物理化学方法,改善其成型技术难度大及产品耐热不足的问题.随着成本的降低以及性能的提高,PLA的应用范围将越来越广,特别是在医学领域,它具有其他材料无可替代的作用.因此,今后应把PLA废料的再利用扩展到医学领域,尝试用新材料对PLA废料进行改性,在克服原有缺点的基础上开发出新用途的PLA材料.The methods of poly-lactic acid waste recycling include the physical modification, chemical mod- ification and physi-chemical modification. At present, domestic and foreign enterprises mainly use physi- chemical methods of tackifying and heat resistance to improve the difficult molding technology and the problem of insufficient heat resistance. With the cost reduction and performance improvement, the applica- tion scope of PLA will be more and more widely, especially in the medical field, it has other irreplaceable role. Therefore, the PLA waste re-use should be extended to the field of medicine, and try to modify PLA waste with new materials to develop new uses of the PLA material in the base of overcoming the shortcom- ings.
