Abstract
Materials researchers are focused on major challenge for effective processing of nanocomposites with polymeric matrix with satisfactory dispersion of the nanometric phase, and a suitable interface between the polymer phase and the nanoparticle. Polyurthane (PU) being most commercialized polymer finding its place in various engineering application and found to be more useful in combination with inorganic nanoparticles. In this study we report the development and characterization of nano CuS embedded PU fiber composite. The PU nanofibers were electrospun by optimizing the parameters namely, applied electric potential, concentration, flowrate. Scanning electron microscope (SEM) images of PU nanofibres electrospun at 13kV, 1ml/h and 10wt% showed uniform mat having a fiber diameter of 175nm. CuS nanoparticles were synthesized by hydrothermal method employing three types of surfactants. The effect of polar and nonpolar solvent on particle size and morphology has also been investigated. Further, the CuS embedded PU/CuS nanofiber composite was developed by electrospinning.
