Preparation and properties of chitosan starch films with different degrees of deacetylation
摘要
Abstract
This study explored the effects of chitosan with different deacetylation degrees on the properties of starch-based composite films.Using potato starch as the substrate,chitosan samples with different deacetylation degrees were incorporated to systematically investigate the variations in mechanical properties,hydrophobicity,thermal stability,and ultraviolet barrier performance of the composite films.The results showed that chitosan with high deacetylation degree could significantly improve the ultraviolet blocking performance of the composite film and effectively block ultraviolet rays.At the same time,the toughness of the composite film was enhanced,yielding a tensile strength of 9.014 MPa.The hydrophobicity of the composite membrane was improved,the contact angle was increased to 75.1 °,the water solubility was 23.62%,and the water vapor permeability coefficient was 9.35×10-11 g·m/(m2·s·Pa).The thermal stability of the composite film was also improved.Among them,FTIR analysis showed that there was hydrogen bonding between chitosan and starch molecules,and the components of each component in the composite membrane were not changed,and the blending modification was successful.The study established how chitosan with varying degrees of deacetylation affected the properties of starch-based films,with the composite films having a high deacetylation degree(85%～95%)showing the best overall performance.关键词
