| 摘 要： | 采用共混法制备了魔芋葡甘聚糖／碳酸钙（KGM／CaCO，）复合膜，研究了影响复合膜拉伸强度的因素。结果表明：KGM浓度在0．8％～1．5％范围内变化时，对KGM／CaC03膜的拉伸强度的影响不大；CaCO3：KGM的质量比在5-10到6：10之间膜的拉伸强度最好；随着表面活性剂量的增加，膜的拉伸强度增加，然而当其量超过1．0％时，KGM／CaC03膜的拉伸强度降低；当pH升至8左右时，KGM／CaC03膜拉伸强度达到最大。复合膜的拉伸强度随紫外照射时间的增加而增加，且在1h时达到最大，超过1h后的辐照将导致复合膜拉伸强度下降。红外光谱分析表明适度的紫外辐照可促使KGM分子之间交联，但过长时间的辐照则导致KGM分子链断裂，膜的拉伸强度降低。

| Abstract: | Composite membranes of Konjac Glucomannan(KGM) and Calcium carbonate(CaCO3) were prepared by blend method.The influencing factors on the tensile strength of KGM/CaCO3 composite films were investigated.The results show that KGM concentration affected slightly on the tensile strength of the composite membranes when it is at the range of 0.8~1.5%.The tensile strength of the films was the highest when the ratio of CaCO3 to KGM is at the range of 5:10 ~6:10.In addition,the tensile strength of the composite films... |
