a Schematic diagram of the composition, structure, and preparation of the ordered OCPS@NNF hydrovoltaic device. b Schematic diagram of the molecular composition of the OCPS@NNFs. c SEM images of Ordered NNF. Scale bar, 2 μm. d SEM images of Ordered OCPS@NNF. Scale bar, 2 μm. e Zeta potential of the NNF (Nylon-66 nanofilms), CPS@NNF (CPS-coated NNF), and OCPS@NNF (Oxidized CPS@NNF). f X-ray photoelectron spectroscopy (XPS) of NNF, CPS@NNF, and OCPS@NNF. g Optical photograph of the diffusion paths of D-OCPS@NNF (Dis-ordered OCPS@NNF) and O-OCPS@NNF (Ordered OCPS@NNF) with 3 μL deionized water droplets. Scale bar, 1 cm. h Optical images of the spreading process of D-OCPS@NNF and O-OCPS@NNF with a 3 μL deionized water droplet. Scale bars, 1 mm. i Pore size distribution of NNF, D-OCPS@NNF, and O-OCPS@NNF measured by mercury intrusion method. j Diffusion height of horizontally placed O-OCPS@NNF, D-OCPS@NNF, and vertically placed O-OCPS@NNF (right figure is an enlarged view within the time range of 0–1 s). k Infrared thermal images of the final diffusion paths of D-OCPS@NNF, and O-OCPS@NNF (left: horizontally placed; right: vertically placed). Scale bars, 1 cm. The error bars in (e) represent the standard deviations from 4 parallel measurements (n = 4). Source data are provided as a Source Data file.
