COMPATIBILIZATION STUDY OF BLENDING POLYMERS PLA-PCL WITH FILLERS CATECHIN-CHITOSAN AS NEW MATERIALS FOR BIOPLASTIC MANUFACTURE

The use of agents in the form of nanochitosan to develop active bioplastics offers a new way to modify the transport properties and release of active compounds while increasing the mechanical resistance and compatibility between polymers. This study aims to study the effect of mixing two polymers in the form of polylactic acid (PLA) and polycaprolactone (PCL) as a matrix and 10% (w/v) filler. The matrix for bioplastic film-forming was prepared by mixing 8 g PLA and 2 g PCL. The internal film and surface microstructures were characterized by scanning electron microscopy (SEM) and interactions between the particles using FT-IR. Mechanical physical properties were reviewed using ASTM D638. The results show that amount of filler composition promotes a significant change in the microstructure of the film and is associated with to improve properties. The amount of nanochitosan (0.9 g) and catechin (0.1) was homogeneously distributed. As a consequence. However, when the filler composition is varied in other quantities, the tensile strength will fluctuate.
