Abstract

Novel composite polymeric material was prepared from coal, carboxymethyl starch (CMS) and polyvinyl alcohol (PVA). Coal was first treated with NaOH to partially dissolve the coal into sodium humate (SH) and the SH along with undissolved residue was blended with CMS and PVA solution to prepare a polymeric composite though hydrogen bonding. The composite materials showed tensile strength in the range of 8–10 MPa for potential applications including plastic bags and films. The residue after coal dissolution in NaOH served as filler while the SH led to bonding with CMS/PVA in water though hydrogen bonds as detected by Fourier Transform Infrared (FTIR) spectroscopy and X-ray Photoelectron Spectroscopy (XPS).
