| Summary: | Environmental concerns of waste paper have led a demanding push to manage the increasing
waste paper from daily use. Recycling paper has not been effective in improving the quality of
paper. To address this problem, cellulosic waste materials were converted into useful
nanocomposite. This provides a very cost-effective way to reduce landfill wastes.
NaOH/thiourea/urea solvent was used to dissolve cellulose under suitable conditions as it is
environmentally friendly and cheap. Silica sol was prepared using sol-gel method and added to
dissolved cellulose to prepare cellulose nanocomposite.The morphology and changes in
functional groups were characterized using Scanning Electron Microscope (SEM) and Fourier
Transfer Infrared (FTIR) spectroscopy |
