FILMES BIODEGRADÁVEIS DE AMIDO DE MANDIOCA, PULULANA E CELULOSE BACTERIANA
The largest consumption of plastics in the world is referred to the synthetic polymers, which are not biodegradable and have a non-renewable source, generating a large environmental impact, especially in urban centers. As a result, in the last two decades several polymers obtained from renewable sources (biopolymers) have been studied as potential raw materials for the production of new biodegradable materials with different applications. The objectives of this study were to produce biodegradable films based on cassava starch, pullulan and bacterial cellulose, and also to characterize these films according to their microstructure, barrier, thermal and mechanical properties. The addition of bacterial cellulose and pullulan to the starch films resulted in films with more homogeneous surfaces, and also decreased solubility and water vapor permeability, and increased elongation and thermal stability.
