A gradient Laponite-crosslinked nanocomposite hydrogel with anisotropic stress and thermo-response

Electric field-induced gradient distribution of Laponite and polymers, taking advantage of colloidal property of Laponie(Lap), as well as interaction between Lap and thermo-responsive monomers, led to anisotropic mechanical property and gradient thermo-response of the nanocomposite hydrogel. An increase in Lap content would improve the comprehensive mechanical property and extend the strength range in different locations of the gradient hydrogel.368
