摘要
以羟丙基甲基纤维素-普鲁兰多糖为主要成分,κ-卡拉胶作为凝胶剂,研究不同组成对复合膜性能的影响,以确定最佳配方。基于单因素实验,对复合膜的配方通过响应曲面法进行优化设计,确定最佳制备工艺为:普鲁兰多糖含量9.533%,羟丙基甲基纤维素含量6.000%,κ-卡拉胶含量2.315%,甘油含量7.903%。在此条件下,经过实验测试,所得到的复合膜断裂伸长率为56.35%±1.48%,抗拉强度为(2.68±0.39) MPa,凝胶强度为(785.48±10.32) g/cm^2,透光率为46.73%±3.87%。实验验证结果与理论值相近,响应面优化所得结果对于复合膜实际生产和深入研究具有一定的指导意义。
Using the HPMC-Pulullan as the main component and the κ-carrageenan as the gelling agent,the influence of different composition ratios on performance indicators was investigated,and then the optimum formula was to be determined. According to the single-factor experiments,the formula design of the composite film was optimized by using the response surface methodology,and then the best preparation process was determined:The contents of pullulan was 9.533%,the contents of HPMC was 6.000%,the contents of κ-carrageenan was 2.315%,and the contents of glycerol was 7.903%. Under these conditions,the experimental results showed that the elongation at break of composite membrane was 56.35%±1.48%,the tensile strength was(2.68±0.39) MPa,the jelly strength was(785.48±10.32) g/cm^2,and the light transmittance was 46.73%±3.87%. The experimental verification results were basically consistent with the theoretical values. Therefore,the results obtained by response surface optimization show certain guiding significance for the actual production and in-depth research of composite membrane.
