摘要
以聚乙烯醇(PVA),丙烯酰胺(AM)和丙烯酸(AA)为原料,以过硫酸铵为引发剂,采用水溶液聚合法合成了互穿网络水凝胶,并对其吸水性、抗盐性和抗温性等性能指标进行了研究,根据正交设计,运用模糊数学的理论和方法处理实验数据,指出影响凝胶吸水率性能指标的显著因素为单体质量比和交联剂Ⅱ用量,影响凝胶抗盐性的显著因素为单体质量比和PVA用量;影响凝胶抗温性的显著因素为引发剂用量和单体用量确定了不用情况下最佳合成条件及配方。
A kind of interpenetrating networks hydrogel is synthesized from polyvinylalcohol (PVA), acrylamide (AM) and acrylic acid (AA) as raw materials, with ammonium persulfate ((NH4)2S2O3) as initiator. And such properties of the hydrogel are studied as water absorptivity, salt resistance and tempreature resistence. Based on orthogonal design, the remarkable influence factors of water-absorptivity are the monomer quality ratio and the crosslinking agent II amount used; and the remarkable influence factors of anti-tempreature performance are the monomer quality ratio and the PVA amount used; the initiator and the monomer amount used affecte anti-tempreature performance of the hydrogel. And the best polyreaction condition can be get by fuzzy mathematical analysis.
