▎ 摘　　要

NOVELTY - Preparing fabric with radiation cooling and photoelectric heat conversion function comprises (i) firstly rinsing fabric substrate and drying, dipping in dopamine hydrochloride solution, taking out and cleaning and drying to obtain fabric modified by dopamine hydrochloride; (ii) dispersing carbon nano material into organic solvent according to the proportion 0.1-0.5 g:1 L, fixing the carbon nano material on the front face of the fabric modified by dopamine hydrochloride by filtering, and drying to obtain fabric with photoelectric heat conversion function; and (iii) weighing polydimethylsiloxane pre-polymer, polydimethylsiloxane curing agent and tetrahydrofuran according to mass ratio of 10:1:500, dissolving the polydimethylsiloxane pre-polymer and polydimethylsiloxane curing agent in tetrahydrofuran, and fully dispersing until forming uniform transparent polydimethylsiloxane solution at room temperature. USE - The method is useful for preparing fabric with radiation cooling and photoelectric heat conversion function. ADVANTAGE - The method realizes excellent self-cleaning performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a fabric with radiation cooling and photoelectric heat conversion function.
