Abstract

Hydrogels are attractive materials for many demanding applications (i.e. medical, scaffolds for soft tissue engineering, organic electronics and optics). One of the recent developments in this field is the fabrication of super tough hydrogels by using several modifications of the double-network concept. These hydrogels can show several hundred percent strains without failure under uniaxial tensile loading condition and reveal excellent fracture toughness and notch sensitivity. The measurements have been done with two different types of nanoparticle filled hydrogels which also showed a variation on the percentage of added nanoclay over a range of 2% to 15%.
