Title:
HYDROGEL CAPABLE OF BEING USED FOR SEAWATER DESALINATION AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/161824
Kind Code:
A1
Abstract:
Disclosed are hydrogel capable of being used for seawater desalination and a preparation method therefor. The hydrogel is a polymer formed by carbon-carbon double-bond polymerization of monomers containing hydrophilic groups and carbon-carbon double bonds; the crosslinking degree of the polymer ranges from 0.01 to 0.2; the mass of the monomers accounts for 5wt% to 50wt% of the mass of the hydrogel. The preparation method of the present invention comprises: mixing monomers, a pore forming agent, a crosslinking agent, an initiator and a catalyst to be uniform, so as to obtain a mixed material; and then transferring the mixed material into a mold, polymerizing the mixed material at the temperature of 20ºC to 30ºC for 2 to 3 hours, and then heating to continue the polymerization until the polymerization is complete, so as to obtain the hydrogel capable of being used for seawater desalination. The method described in the present invention is convenient and quick, so that the present invention has the advantage that the present invention can be used under special conditions such as earthquake relief, maritime rescue and field exploration.
