A facile approach for synthesising and studying (chitosan-g-poly vinyl alcohol)/bio-CaCO3 fire retardant bionanocomposites
Autor: Prafulla K. Sahoo, Dharmendra K. Jena
Publikováno v: Polymer Bulletin. 79:6673-6691
We describe a facile approach for the preparation and characterization of a chitosan (CS) based fire safety bionanocomposite via emulsifier-free emulsion polymerisation. The resulting nanostructure as well as molecular interactions in the (chitosan-g
