Deep co-deposition of polydopamine in PVDF hydrogel to enhance photothermal evaporation efficiency.

ABSTRACT: Polydopamine (PDA) is a widely utilized photothermal conversion material recognized for its ease of synthesis and environmental friendliness. However, its relatively weak light absorption capabilities lead to lower photothermal efficiency, restricting its application in solar steam generation (STG) processes. To effectively enhance light absorption, this study introduces a deep co-deposition method for the microstructural design of STG membranes. Unlike traditional surface co-deposition methods, which coat a layer of PDA on the membrane surface, the deep co-deposition method allows for the incorporation of PDA within the internal nanohydrogel structural units of the membrane. This approach significantly increases the PDA loading, resulting in a marked enhancement of light absorption capabi
