“…Due to CMP's rigid π-conjugated structure, large specific surface areas, and tunable porous structure, the evaporation rate of the material in water under a solar light reaches 1.4406 kg m −2 h −1 . And Sun 15 prepared a multifunctional self-floating based on candle soot-coated conjugated microporous polymer hollow spheres (CS-CMPsHM) evaporator. Due to the porous structure of CMPsHM, which is conducive to light capture and water transport, the evaporation rate of CS CMPsHM under one sunlight reached 1.55 kg m −2 h −1 .…”

Solar interfacial evaporation is the most promising route for desalination because it is highly efficient, affordable and offers green energy. Polyurethane foam (PUF) is an ideal substrate material for efficient solar water evaporation because of its low thermal conductivity, affordability, and high efficiency for continuous water transport. However, PUF exhibits poor mechanical properties after water absorption and expansion, and lacks the photothermal conversion effect. In this study, biorefinery lignin with efficient photothermal properties was introduced to prepare functional lignin-based PUF (LPUF), and the relationship between the molecular structure of fractioned lignin and the solar water evaporation performance was systematically investigated. The addition of lignin effectively enhanced the mechanical properties of LPUF after water absorption and swelling, and imparted the foam with a photothermal conversion effect. The water evaporation rate of LPUF was as high as 2.58 kg m −2 h −1 and could be further improved to more than 3.0 kg m −2 h −1 after loading polyaniline (PANI) on the surface of LPUF. LPUF−PANI exerted an excellent purification effect on dye wastewater with outstanding long-term stability, providing a potential solution for ecofriendly and sustainable economic production of fresh water. This study broadens the effective utilization of LPUF bulk materials in the fields of energy and environment.

Solar steam generation (SSG) has been regarded as a promising technique due to its potential in seawater desalination. Photothermal conversion materials derived from biomass are good evaporators for SSG because of their sustainability and high efficiency. Herein, 3D cylindrical structured composite materials based on gourd flesh and polypyrrole (GPPY) were designed and used for high efficient SSG. The polypyrrole layer was deposited on the gourd flesh to provide broad optical absorption ability and high photothermal conversion efficiency. Besides, gourd flesh with porous structure could act as thermal insulators, confine the generated heat within the evaporative surface and facilitate the efficient transport of water to the photothermally active area. Based on these characteristics of the composite, the evaporator made of GPPY could achieve a high evaporation rate of (1.63 kg·m‐2·h‐1), and a superior photothermal conversion efficiency 95.8% under one solar irradiation (1 kW·m‐2). The GPPY could be expected to be a practical photothermal conversion material for commercial SSG based on its high efficiency and sustainability.This article is protected by copyright.
