Abstract:

This paper reviewed the biodegradation performance of poly(lactic acid) composites and summarized the variation trends in their mechanical properties, thermal properties, biocompatibility, antibacterial properties, and biodegradation rate under different environmental conditions after compounded with organic substances such as lignin, cellulose, etc. and inorganic substances such as calcium carbonate, nano silver particles, etc. Furthermore, the material structures of polylactic acid composites and the relationship between the compositions and degradation properties were discussed, and the application prospect of poly(lactic acid) composites with controllable degradation properties was prospected.

Key words: poly(lactic acid), biodegradability, environmentally friendly polymer
