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。
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.
