Abstract:
Development of biomaterials from renewable sources is gaining increasing interest and importance over the past decades, due to several reasons related to environmental protection, public health, and most importantly, new legislative requirements. This suggests and encourages the development and use of biodegradable polymers, especially in the field of packaging, where large amounts of plastics are used and contact with biodegradable items (such as for instance, food) is frequent [1]. Poly(lactic acid) (PLA) is absolutely one of the most important biodegradable polymers; Mater-Bi is also a biodegradable/compostable polymer that is receiving increasing commercial interest. Both can be considered as alternatives for traditional, petroleum-based polymers, and show interesting nontoxicity and biodegradation characteristics [2].
In addition to this, it is further of interest to take into account the possibility of using biodegradable polymers as matrices for bio-nanocomposites, since it is already known that nanocomposites can show improved mechanical, rheological, and barrier properties [3, 4] in comparison to the corresponding matrices.
We investigated the behavior of different biodegradable polymers and different nanocomposites based on biodegradable polymers, in terms of processability, mechanical, and rheological properties. In particular, different processing techniques were adopted (injection molding, film blowing, fiber drawing) and comparison with petroleum-based counterparts was also taken into account.
