Abstract Tuning the surface topography of solar evaporators is significance for boosting light absorption and enhancing solar‐to‐vapor efficiency. Herein, a novel strategy to manipulate graphene oxide (GO) via electrostatic assembly coupled with in situ polymerizations aniline reported. The GO fully hybridized polyaniline (PANI) nanocone arrays, manifesting periodic structures highly foldable configurations. Additionally, PANI arrays tune chemistry retard redispersion into water, thus enabling corresponding composite (PG) robust structural durability. Featuring these intriguing attributes, when applied as an evaporator pure PG delivers improved evaporation performance 1.42 kg m −2 h −1 high efficiency 96.6% under one sun illumination. Further investigations reveal that periodically conical over strengthen multiple reflections facilitate heat localization. Desalination test substantiates reliability practical freshwater production. numerical simulations optical microscopy observation exhibit topography‐strengthened vapor generation effect.
