ABSTRACT Solar‐powered interfacial evaporation technology is seen as a potential way to alleviate the crisis of water scarcity through seawater desalination. The key success this hinges upon efficient conversion solar energy into heat energy, which intimately connected with innovative development composite photothermal membranes. In study, polyaniline (PANI) excellent light absorption and carbon black (CB) good stability were added polymer material polyaryl ether nitrile (PEN), PANI/CB‐PEN nanofiber membrane was prepared by electrospinning blending. Due PEN polymer, evaporator has salt resistance stability. results show that fiber best effect when reaction time 80 min CB content 50.0%. temperature can reach 68.6°C, rate 1.51 kg m −2 h −1 , while 1.38 in 3.5% NaCl brine. efficiency 94.17%. membrane‐based device demonstrates sustained performance repeated tests, showing promising for long‐term, scalable solar‐powered desalination applications.
