| titleOfInvention | Preparation method of low-swelling high-strength hydrogel obtained through hybrid crosslinking and pre-stretching |
| abstract | The invention provides a preparation method of low-swelling high-strength hydrogel obtained by hybrid crosslinking and pre-stretching. Firstly, sodium silicate, acrylamide and sodium alginate are dissolved in water together to initiate acrylamide polymerization, and calcium silicate nano particles are generated in situ in hydrogel through calcium ion crosslinking. Calcium silicate and alginate molecular chains are crosslinked through calcium ions to form organic-inorganic hybrid structures, the hybrid structures improve the stability of an alginate gel network, enhance the entanglement between the alginate network and a polyacrylamide network, share the stress transferred by deformation of a bearing network, improve the strength of the hybrid hydrogel and reduce the swelling of the hybrid hydrogel in a physiological environment. Reacting hydrogen ions released by hydrolysis of the gluconic acid-delta-lactone with calcium silicate to generate the calcium silicate with mesoporous silica gel on the surface. The nano particles and the polymer in the hydrogel are oriented through pre-stretching treatment, so that the strength of the hybrid hydrogel is further improved. |
