The fabric is prepared by an electrospray of poly(vinylidene fluoride-hexafluoropropylene) (PVDF-HFP) on one-side of the fabric followed by dip-coating of the fabric with carbon black as a photothermal absorber.  The tunable water delivery capability of the fabric regulates the amount of water supplied to the vicinity of the photothermal absorber.  Additionally, the fabric shows excellent broadband absorption and low thermal conductivity.
