Abstract

In this paper, ethylenebisformamide was synthesized and used as a novel plasticizer for corn starch to prepare thermoplastic starch (EPTPS). FT-IR spectra showed that the absorption bands of the C-O groups of the starch molecules were shifted to lower wavenumbers, which indicated that a strong and stable hydrogen bond had been formed between ethylenebisformamide and starch. By scanning electron microscope (SEM) native individual corn starch granules were proved to transfer to a continuous phase. The crystallinity of native corn starch, GPTPS (glycerol plasticized corn starch) and EPTPS was characterized by X-ray diffraction (XRD). Water resistance of EPTPS was better than that of GPTPS. It decreased from 50.2% for GPTPS to 37.8% for EIPTPS. The mechanical analysis showed that elongation at break increased markedly, being 260% for the EPTPS containing 35% (w/w) ethylenebisformamide. Thermal stability of GPTPSs and EPTPSs was also determined by thermogravimetric analysis (TGA). The glass transition temperature T-g, as measured by dynamic mechanical thermal analysis (DMTA), of EPTPS was higher than that of GPTPS.
