摘要:

研究增塑剂对羧甲基纤维素(CMC)膜、甲基纤维素(MC)膜性能的影响,并利用扫描电镜、红外光谱仪和X 射线衍射仪探讨增塑剂对膜的作用机理。实验结果表明:0.2% 甘油对CMC 膜的增塑效果较好,而0.4% 聚乙二醇对MC 膜的增塑效果较好。增塑剂对膜性能的影响由增塑剂与膜材的相容性决定。

关键词: CMC膜, MC膜, 增塑剂

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
