Abstract:
To overcome the weaknesses of poly(lactic acid) or PLA, bacterial cellulose (BC), which has high mechanical and thermal properties as well as is renewable and biodegradable, was incorporated into the PLA-based nanocomposite films in this study. The effects of BC addition and its surface modification on structure and properties of the resulting PLA films were investigated. For the films preparation, firstly, PLA mats were prepared by electrospinning and BC pellicles produced by the cultivation of Acetobacter xylinum, was disintegrated into the BC suspension. Next, it was filtered onto the stacking PLA mats at varied contents (1-10 wt%) and dried. The stacking PLA/BC mats were then compressed at 165 °C for 40 seconds to prepare the nanocomposite films. It was found that the resulting films showed an unusual high degree of crystallinity and both strength and toughness of these films were impressively improved with the BC integration as well as their thermal and barrier properties. It was not only due to the reinforcing effect of BC but also the unique processing technique applied which resulted in the unique film structure and great film performance as a consequence. Moreover, after surface modifying BC with 3-
(trimethoxysilyl) propyl methacrylate, a further enhancement in mechanical and barrier properties of the nanocomposite films was gained due to the stronger interfacial interaction between the PLA matrix and modified BC phase.
