Hydrogel for intelligent irrigation control valve and preparation method thereof

The invention relates to hydrogel for an intelligent irrigation control valve and a preparation method thereof, and the preparation method comprises the following steps: adding N-hydroxymethyl acrylamide, acrylic acid, poly (3, 4-ethylenedioxythiophene)-polystyrene sulfonate and an oxidation-reduction initiator into water, and uniformly dispersing to form a reaction solution; and heating the reaction liquid, and carrying out in-situ polymerization molding to obtain the hydrogel for the intelligent irrigation control valve. According to the hydrogel material provided by the invention, an oxidation-reduction initiation system is used, so that the preparation process of the hydrogel is simplified, and the reaction is mild; the hydrogel with the P (AA-co-N-MA)/PEDOT: PSS dual-network structure is formed, has excellent mechanical property, conductivity, sensing property, self-repairing property and humidity sensitivity, and can be used in an intelligent irrigation control valve. 本发明涉及一种用于智能灌溉控制阀的水凝胶及其制备方法，包括以下步骤：将
