| titleOfInvention | Polyaspartic acid semi-interpenetrating nano-composite hydrogel and preparation process thereof |
| abstract | The invention relates to a polyaspartic acid semi-interpenetrating nano composite hydrogel, the acrylamide monomer is a non-ionic monomer, can improve the salt resistance of the hydrogel and improve the quality of the hydrogel, the linear macromolecular polyvinyl alcohol can form a semi-interpenetrating polymer network structure and simultaneously greatly improve the mechanical property of the composite hydrogel, the biomass raw material polyaspartic acid is a non-toxic, harmless and degradable environment-friendly material, is environment-friendly, contains a large amount of carboxyl and amide groups, enables a molecular chain to have good water solubility, can improve the hydration of the hydrogel when the content is less, in addition, the bentonite contains a large amount of cations, is easy to ionize and disperse in a polymer network to enhance the hydrophilicity of the composite material and increase the water absorption of the composite material, and the bentonite is salt-resistant clay and is introduced into the polymer network, can greatly enhance the salt resistance. |
