Study on the Preparation of Full Bio-based Soy Protein Film Reinforced by Oxidized Cellulose
摘要
Abstract
A series of full bio-based soybean protein films(SPFO-X)were prepared by utilizing the self-assembly effect of soybean protein and the Schiff base reaction between oxidized cellulose(OMCC)and the amino groups of soybean protein.The structural changes of soybean protein were investigated using transmission electron microscopy(TEM)and circular dichroism(CD)spectroscopy.The structure and properties of the fully bio-based soybean protein film materials were characterized by scanning electron microscopy(SEM),fourier transform infrared spectroscopy(FT-IR),X-ray photoelectron spectroscopy(XPS),and other techniques.The experimental results demonstrated that the spatial structure of soybean protein was disrupted during the ultrasonic treatment,leading to the self-assembly of highly crystalline fibrillar structures.This fibrillar structure significantly enhanced the mechanical properties of the film,increasing the tensile strength from 8.7 MPa(unfibrotic soy protein film)to 27.8 MPa.With the addition of OMCC,the aldehyde and amino groups underwent a Schiff base reaction,which further improved the tensile strength of the soybean protein-based film.When 10%OMCC was added,the tensile strength of the resulting film,SPFO-10,increased to 66.1 MPa.Solvent resistance and recovery tests revealed that the fully bio-based soybean protein films could withstand corrosion by various common solvents and be effectively degraded using specific solvents.关键词
