摘要: 以丙烯酸和琼脂为主要原料、Fe²⁺/过硫酸铵为氧化/还原引发体系，制备具有高弹性的双网络水凝胶.通过研究丙烯酸和Fe²⁺含量对水凝胶性能的影响，得出适宜的工艺条件为琼脂溶液质量浓度1%，丙烯酸质量分数30%，过硫酸铵质量分数1.5%，N，N'-亚甲基双丙烯酰胺质量分数0.3%，硫酸亚铁质量分数0.050%.对该条件下制备的水凝胶的力学性能进行分析测试发现，水凝胶的断裂拉伸率可达225%，抗压能力可达4 MPa，具有良好的拉伸和压缩性能.利用SEM，IR对该水凝胶进行微观形貌分析和结构表征发现，水凝胶的微观形貌具有纤维网络结构，纤维直径约为100 nm，琼脂与聚丙烯酸之间存在分子间氢键作用，Fe³⁺与聚丙烯酸分子中的羧酸基因发生了金属络合作用.

Abstract: Dual-network hydrogels with high elasticity were prepared by oxidation/reduction (Fe²⁺/ammonium persulfate) initiation system using acrylic acid and agar as the main raw materials.The optimum conditions were obtained as follows:agar mass concentration was 1%,masacrylic acid concentration was 30% (mass fraction),ammonium persulfate concentration was 1.5% (mass fraction),N,N'-Methylenebisacrylamide concentration was 0.3% (mass fraction),and ferrous sulfate concentration was 0.050% (mass fraction).Through the analysis of the mechanical properties of the gel,it was found that the tensile elongation of the gel was 225% and the compressive capacity was 4 MPa,exhibiting good stretch and compression performance.The microstructure of the hydrogel were analyzed by IR using SEM.The results showed that the hydrogel has a fiber network structure with a fiber diameter of about 100 nm, there was intermolecular hydrogen bonding between agar and polyacrylic acid and the metal complexation between Fe³⁺ and polyacrylic acid molecules.
