Preparation of Zein Film Through Self-assembly Assisted Electric Inducement and its Properties
摘要
Abstract
A method for the preparation of zein film was developed using indium-tin oxide conductive glass (ITO) adsorbed with-COOH (hydrophilic) and-CH3 (hydrophobic) end groups respectively as electrodes.Zein was modified,so that the molecules were induced to start the progress of self-assembly and form a highly ordered and stable film.The film properties,before and after the electric inducement,were studied.It was found that when the ethanol concentration was 90％,the overall quality was the best.After being modified,the film improved its properties and gained a trend towards the hydrophilic direction;its tensile strength is (40.6 ± 0.8) MPa,elongation at break (7.3 ± 0.3) ％,contact angle 69.39° ± 0.36°,water absorption rate (25.12 ± 0.71) ％,water vapor permeability (68.53 ± 1.82) g/(m2.d),and the melting temperature increased to 122.37 ℃.Scanning electron microscope (SEM)revealed that the modified film microstructure became smoother and more compact.关键词
