A Study on the Acetylation Degree of Chitosan and Its Effects on the Physical Properties of Antibacterial Membrane in the Polyurethane Lamination Process

摘要

This article aims to explore how the thermoplastic polyurethane(TPU)affects the various conditions of chitosan.Several processes were used and two of them are the TPU film and chitosan lamination process intended to complete a membrane,and the TPU and chitosan blending process designed to manufacture a film.This research shall also probe into the acetylation degree of chitosan so as to understand how an increase in content may affect the antibacterial qualities,manufacturing process,mechanism,and thermal properties.
