摘要
本研究采用冷冻—融化方法,正交试验设计考察了聚乙烯醇(PVA)与聚丙烯酸(PAA)复合水凝胶含水率的影响因素(原料配比、交联剂用量、冷冻时间、冻融次数)并得到合成的最佳条件。通过红外光谱分析对产物结构进行了表征。
The optimum condition(the ratio of raw material, the use level of crosslinbers, the temperature of freezing and number of times of freezing and thawing) for (PVA)/(PAA) hydrogel's moisture by orthogonal design, through freezing and thawing. The structure of product was characterized by infrared spectrum (IR).
