Summary:Photoconductive materials have important application value because of their special property of variable conductivity under light. Due to the limitations of the construction of single-component photoconductive materials, photoconductive materials are often combined with organic polymer materials to prepare composite materials. In this work, a series of photoconductive nanofibers array films (PNAFs) are prepared by combining polyvinyl pyrrolidone (PVP), polyacrylonitrile (PAN), polymethyl methacrylate (PMMA), polyoxyethylene (PEO) + PMMA, and polyvinylidene fluoride (PVDF) + PVP polymer substrates with 2,7-dibromo-9-fluorenone (DF), respectively, innovative combination of photoconductive materials with different polymers. PNAFs have excellent green fluorescence and electrical conductivity under light irradiation but no performance under no light irradiation. The transformation of performance can be achieved by the presence or absence of lighting. The effects of the combination of different substrates and photoconductive materials on the conductivity and fluorescent properties of the products are investigated for the first time. This provides ideas for the research of photoconductive materials in the future, and suitable combinations of inorganic and organic substances can be selected according to actual needs.
