A number of methods are available for preparing a fiber reinforced polymer composite from two or more polymer matrixes and fibers. We propose new type reinforced polymer composites by electrospinning technique with in situ coffining process. We prepared the reinforced composites that have the structure with one-dimensional polymer fibers (poly(acrylonitrile), PAN, poly( -caprolactone), PCL, and Nylon 6,6, Nylon) in situ coffined into the poly(vinyl alcohol) (PVA) matrix by electrospinning technique. The SEM images of the PVA-PAN(es) (PVA-PAN(es) suggest that the PAN fibers are electrospun on the PVA aqueous solution), the PVA-PCL(es) and the PVA-Nylon(es) composite film prepared by in situ coffining method. Average diameter of the PAN fibers is 1.3 um, of the PCL fibers is 1.69 um and of the Nylon fibers is 0.362 um. The amount of PAN fibers on/in PVA film is lower than those of PCL and Nylon fibers. The fiber density and average diameter of the fibers on the PVA films depend on the electrospun time, the kind of polymer, and the concentration of polymer solution for the electrospinning process. The light transmittance of PVA-Nylon(es) composite films and their appearance images. The light transmittance of PVA-Nylon(es) composite film at 400 nm is ca. 60%.
