| titleOfInvention | A kind of composite polyacrylamide gel and its preparation method and application |
| abstract | The invention relates to the technical field of new materials, and discloses a composite polyacrylamide gel, a preparation method and application thereof. The preparation method comprises the following steps: adding 0.005 to 0.05 g of methylenebisacrylamide to the acrylamide-sodium alginate solution prepared in 100 mL of S2 and continuing to stir and dissolve; then adding 1 to 4 mL of S1 polyacrylamide solution to continue uniformity; Add 50-200μL ammonium persulfate solution, 0.01-0.5g calcium sulfate powder, 0.5-3mL glycerin, 1-3mL propylene glycol to the acrylamide-sodium alginate solution, stir well; Add 4-15 μL of tetramethylethylenediamine, continue to stir for 0.5-5 minutes, then pour it into a glass splint, and place it in a refrigerator at 4°C for 8-20 hours to form a composite polyacrylamide gel. The composite polyacrylamide gel of the present invention has excellent tensile deformation ability, and the tensile deformation ability, softness, fatigue resistance, etc. of the gel prepared by the present invention are obviously better than the polyacrylamide gel prepared by the prior art . |
