Films and coatings produced from biopolymers and composites

Abstract

Biodegradable polymers can be defined as those that undergo a significant change in chemical structure under specific environmental conditions. These changes result in a loss of physical and mechanical properties, as measured by standard methods. Biodegradation is defined by standard methods like International Standard Organization (ISO), American Society for Testing of Materials (ASTM), European Committee for Standardization (CES), and others. For example, the ISO standards take into account the conversion of organic carbon in CO2and at the CES standards, this evaluation is carried out through the mass loss and fragmentation of the material.
