Study on the Glass Transition and Surface Structure of Zein Film

Abstract

Abstract: According to the results of differential thermal analysis (DTA) and thermogravimetry (TG) of a zein film, its glass transition temPerature (Tg) is 171℃ and the decomposition temperature is 262℃. Heat treatment of the film at temperature above Tg, some defects of the film may be dacorated. The effects of film forming condition on configuration structure of the film by seanning electron microscoPe (SEM) were discussed.

Key words: Zeinfilm, DTA, TG, Glass transition temperature, Decomposition temperature, Configuration structure
