Preparation and optical properties of nickel nanoparticles implanted carbon membranes

Abstract

Through dip coating method monodisperse nickel nanoparticles assisted carbon membrane was prepared on porous alumina disc support. The coating solution was prepared by blending of thermally stable polymer polyphenylene oxide (PPO) and thermally labile polymer polyvinylpyrrolidone (PVP) followed by addition of nickel nanoparticles. Size of nanoparticles, surface porosity, average pore size, element composition and optical properties of the membrane were investigated by means of different techniques such as XRD, FE-SEM, EDS and UV-Visible spectrometer Incorporation of nano-sized nickel in polymer matrix causes increase in pore size from 0.022 μm to 0.076 μm as well as porosity and decrease in optical band gap from 5.44 eV to 5.09 eV of membrane.
