Synthesis and properties of hectorite/poly(AM/IA) nanocomposite hydrogels with high gel strength
Lan Wang Wenzhong Cheng Tao Wan Ziwen Hu Min Xu Ruixiang Li Chuzhang Zou
A novel hectorite/poly(AM/IA)nanocomposite hydrogel was synthesized by inverse microemulsion polymerization. The influence of hectorite amount on water absorbency rate, gel strength and shearresistance was investigated. Dynamic viscoelasticity behaviour of the nanocomposite hydrogels was also studied. The nanocomposite hydrogels showed suitable water absorbency and shear-resistance, high gel strength, solid-like behaviour in the whole oscillation frequency region and enhanced viscoelastic behaviours under high stress. TEM indicated that the as-synthesized hydrogel particles were regular and spherical in shape with an average particle size of 43 nm in the range of 30-65 nm.
