Abstract

Abstract:

Effect of plasticizers on properties of carboxymethyl cellulose (CMC) and methyl cellulose (MC) films was studied, and the mechanism was discussed through scanning electron microscopic (SME), infrared spectrometric and X-ray diffractometric observations. Results showed that 0.2% glycerol added exhibited a good plasticizing effect on CMC films, while, for MC films, the optimal plasticizer was polyethylene glycol at a concentration of 0.4%. The effect of plasticizers on film properties depended on the material-plasticizer compatibility.

Key words: CMC film, MC film, plasticizer
