Which effect occurs when applying shear stress to hydrogels?

💡 Explanation

Hydrogels exhibit shear thinning because the shear stress disrupts secondary molecular bonds linking cross-linked polymer chains, resulting in reduced viscosity. Therefore, the viscosity lessens, rather than changes like crystallization or elasticity which do not fit this mechanism.
