Title:
NANOCOMPOSITE HYDROGEL MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/205350
Kind Code:
A1
Abstract:
Provided are a nanocomposite hydrogel material and a preparation method therefor, the nanocomposite hydrogel material being prepared by reinforcing polyacrylamide with calcium hydroxide nanospheres (CNS). The hydrogel is formed by forming CNS by means of the crystallization of calcium ions of tricalcium silicate, dicalcium silicate, Portland cement or other cementing materials containing a calcium component at 0ºC, and uniformly diffusing same into a acrylamide polymer matrix and subjecting same to acrylamide polymer in situ polymerization and crosslinking with CNS. The uniformly dispersed CNS is a hydration product of the calcium-containing component cementing material at 0 degrees and functions as a crosslinking agent in the polyacrylamide polymer network. The nanocomposite hydrogel has superior mechanical strength, elasticity, ultra-high ultimate strain, toughness and recoverability, and maintains the transparency and low cost of traditional PAM hydrogels.
