POCl3处理对Zein溶液的黏度及Zein膜的表面/机械性质的影响
EFFECT OF POCl3 TREATMENT ON RHEOLOGICAL PROPERTIES OF ZEIN SOLUTION AND SURFACE/MECHANICAL PROPERTIES OF ZEIN FILMS
摘要
Abstract
A new chemical method was employed for improving the properties of zein film. The rheology of zein solutions and surface/mechanical properties of zein films were studied. The apparent viscosity of phosphorylated zein solution was increased remarkably and the magnitude of increase was different at different pH levels. Higher viscosity change was observed in zein solutions phosphorylated at pH 7 and pH 9. The atomic force microscopy (AFM) of modified zein film showed stone-like structure and higher roughness parameter (Rq) than unmodified zein film. Apparent contact angle decreased slightly with phosphorylation except the film modified at pH 7 (possessing the highest basal side water contact angle of 81°). Phosphorylated zein films had a relatively lower tensile strength (TS) and a higher elongation at break (EB) than the pure zein films, especially at pH 7 and pH 9, in which EB increased dramatically up to 150.17% and 122.72%, respectively.关键词
