Compatibilization and Reinforcement of PHB/PBAT Blends via Sequential Blending of Surface‐Modified Cellulose

open access: yesPolymer Engineering &Science, EarlyView.
Sequential blending improved the mechancial properties of PHB/PBAT/cellulose composites as compared to the one‐step batch mixing method. ABSTRACT Polyhydroxybutyrate (PHB) is a natural and biodegradable polymer generated by bacteria. While its applications to potentially replace petroleum‐based plastics are severely limited due to its brittleness and ...
