The invention discloses an acid mist absorption-water release intelligent solar hydrogel and a preparation method and application thereof.The preparation method comprises the steps that an N-isopropylacrylamide monomer and a methacrylic acid N, N-dimethylaminoethyl ester monomer serve as raw materials, N, N-methylene bisacrylamide serves as a cross-linking agent, ammonium persulfate serves as an initiator, a crosslinking agent serves as a crosslinking agent, a crosslinking agent serves as a crosslinking agent, and a crosslinking agent serves as a crosslinking agent; and carrying out free radical polymerization to synthesize the P (NIPAAm-co-DMAEMA) porous network hydrogel. The P (NIPAAm-co-DMAEMA) hydrogel prepared by the preparation method disclosed by the invention shows ultra-strong acid mist absorption performance (about 6.5 g/g), high-density water storage, ultra-fast water release performance (about 90%) and high cycle stability (about 25 cycles). 本发明公开了一种酸雾吸收-水释放的智能太阳能水凝胶及其制备方法和应用，其制备方法包括：以N-异丙基丙烯酰胺单体和
