As the material basis for the survival of life, fresh water resources are facing serious challenges. Using efficient solar-driven interface evaporation (SSG) is an important means to solve the current water shortage. A new porous material conjugated microporous polymer (CMPs) plays an important role in water treatment technology. A new type of solar energy evaporator (CMC/SCMP-PPY) was prepared by spraying polypyrrole on its surface with CMCZ SC MIy as a precursor. The light absorption rate was up to 91 % and the photothermal conversion ability was realized. The aerogel showed good photothermal conversion performance under 1 kW/mJ irradiation, and the evaporation efficiency reached 85.57%. The porous structure and hydrophilic characteristics make it have excellent water transport ability, and the stable chemical structure makes it have excellent salt resistance to prevent salt crystal deposition and clogging material channels, so that it can realize the photothermal conversion ability. This work further optimizes the purification of CMPs in wastewater, realizes the utilization of clean energy, and provides a new idea for the development of new photothermal materials.
