Description

technical field [0001] The invention relates to a preparation method of polyacrylic acid / cellulose graft (N-(4-aminophenyl) acrylamide) grafted polyaniline interpenetrating network polymer hydrogel, that is, cellulose-based interpenetrating network polymer The hydrogel belongs to the technical field of electrochemical materials. Background technique [0002] Hydrogel is a kind of "soft matter" with rich three-dimensional network structure, which can maintain a certain shape in water and is not dissolved by water, showing excellent water retention and gel stability. Introducing a conductive medium into the hydrogel system to make it into a conductive hydrogel has attracted extensive attention from researchers in recent years. Conductive hydrogel is an organic combination of hydrophilic matrix and conductive medium. It is a new type of composite hydrogel with both flexibility and electrochemical properties. It has broad application prospects in the fields of flexible wearable...
