柳橙皮基可降解膜的制备及其性能研究
Study on the preparation and properties of citurs pericarp-based biodegradable film
摘要
Abstract
To assess the preparation and performance of the a new biodegradable film,tape casting was applied to prepare a citrus pericarp based film using sodium alginate and carboxymethyl cellulose as a thickening agent,and glycerin as a plasticizer.The influence of different concentrations of citrus pericarp,thickening agent,and plasticizer on the mechanical and barrier properties of the film were investigated.As a result,each index was present well while citrus pericarp mass concentration was 1.5％,sodium alginate mass concentration was 0.1％,carboxymethyl cellulose mass concentration was 0.2％ and glycerin mass concentration was 0.2％.At this composition,the tensile strength was 24.08 MPa,the elongation of the film at the breaking point was 15.73％,and the water vapor permeability was 1.686×10-12 g· cm· cm-2· s-1·Pa-1.In conclusion,the citrus pericarp is shown to be a good base for a biodegradable film.It produces a film with good mechanical and barrier properties and has promising potential for the production of new packaging materials.关键词
