Abstract: A hydrogel capable of desalinating seawater and a preparation method thereof. The hydrogel is a polymer polymerized by a monomer containing a hydrophilic group and a carbon-carbon double bond via carbon-carbon double bonds. A degree of crosslinking of the polymer is 0.01 to 0.2. The monomer accounts for 5 wt % to 50 wt % of a mass of the hydrogel. The preparation method includes: mixing a monomer with a pore-forming agent, a cross-linking agent, a initiator and a catalyst evenly, obtaining a mixed material, then transferring the mixed material into a die; conducting a polymerization for 2 to 3 hours at a temperature of 20° C. to 30° C. first, followed by increasing the temperature to continue the polymerization until the polymerization is completed; and obtaining the hydrogel capable of desalinating seawater. The method according is convenient and efficient, and has advantages of being used under special conditions such as earthquake relief work, maritime rescue and wild adventure.
