  • 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.
