Bacterial Cellulose Nanofiber Reinforced Poly (lactic acid) Nanocomposite

Recent developments in the synthetic degradable polymers have been the subject of significant interest for macromolecular science to both of an environmental and biomedical perspective with dedication towards applications in tissue engineering and drug delivery. The best candidate for degradable polymer is poly (lactic acid) (PLA), which is described as aliphatic polyester [1]. It is produced from renewable resources of agriculture via combined fermentation and polymerization processes. Considering that PLA has several remarkable properties, such as relatively high modulus and hardness at ambient temperature, it is a candidate as a replacement for traditional petroleum based polymers. In contrast, the PLA application is still restricted because of the low glass transition temperatures (Tg), vicat soft temperature (VST), and frailty [2,3]. The blending of binary degradable polymers and copolymerization can enhance the limitation of mechanical properties [4]. However, immiscibility and non-compatibility are considerable barriers in developing PLA with superior properties [5].
