Although poly(L-lactic acid) (PLLA) is well-known biocompatible and biodegradable aliphatic polyesters, it has limitations to widely apply in many fields due to the comparatively poor mechanical properties and flexibility. In this study, PLLA/bacterial cellulose composite films were prepared by compounding dried bacterial cellulose pellicles into PLLA matrix to overcome the problems we described above. Bacterial cellulose possessing unique properties such as high Young's modulus, high purity and unusual physico-chemical characteristics as well as biocompatibility improved the flexibility of the composite films by reinforcing PLLA matrix with keeping intrinsic biodegradability of PLLA. |
