Preparation and Properties of Nanocellulose/Chitosan/Gelatin Composite Films
摘要
Abstract
With gelatin(Gel), chitosan(CS), nanocellulose(NCC) as raw materials,the nanocellulose/chitosan/gelatin(NCC/CS/Gel) composite films with different NCC and CS mass ratios were prepared by solution blending method. The light transmittance, microstructure, chemical composition, crystal structure, thermal properties and mechanical properties of the composite films were characterized by UV-Vis spectrophotometer,scanning electron microscopy(SEM),Fourier transform infrared spectroscopy(FT-IR), X-ray diffraction(XRD), thermal analyser(TGA) and texture analyser. The results showed that the nanocellulose,chitosan and gelatin formed network structure with strong interaction. It could be seen that the composite fimls had smooth surface,uniform dispersion and good compatibility. With the increasing of NCC content, the transmittance of NCC/CS/Gel composite films decreased. Compared with CS, the light thermal stability of the composite films was remarkably improved. When the mass ratio of NCC to CS was 7:1,the tensile strength of NCC/CS/Gel composite films was up to 33 MPa,elongation at break could reach 14.9 %,the maximum water absorption rate could reach 341 %.关键词
