Preparation and Properties of Starch-based Dynamic Imine Polymer/Nanocellulose Composite Film
摘要
Abstract
Starch-based dynamic imine polymer(Starch-PI)was synthesized by crosslinking dialdehyde starch(DAS)with diamine through Schiff base reaction,and Starch-PI/CNFs composite film was obtained by compounding Starch-PI with nanocellulose(CNFs).The chemical structure and morphology were characterized by Fourier transform infrared spectroscopy(FT-IR),X-ray diffraction(XRD),and scanning electron microscopy(SEM),which proved that the Starch-PI/CNFs composite film was successfully prepared.The tensile tests showed that when the mass fraction of CNFs was 2％,the composite film had the best mechanical properties.And the tensile strength,Young's modulus,and elongation at break were 23.5 MPa,326.9 MPa and 15.6％,respectively.The dynamic mechanical analysis(DMA)tests showed that the glass transition temperature(Tg)of Starch-PI/CNFs-2％composite film was 202.5 ℃.The Starch-PI/CNFs-2％composite film also possessed self-healable,shapeable,and degradable properties.关键词
