Facile Functionalization of Charcoal by a Green Approach

The ability of charcoal, a low-cost material derived from biomass pyrolysis, to be functionalized via cation exchange in an aqueous solution, providing new interesting fillers with possible antimicrobial and flame-retardant properties, is discussed here. adducts obtained through this sustainable procedure, show significant uptake close 30% by weight well-known quaternary phosphonium salts, tetraphenyl bromide, dodecyl triphenyl bromide. materials were characterized elemental analysis, wide-angle X-ray diffraction, infrared spectroscopy, thermogravimetry. Additionally, study changing the ratio between reagents for both was performed improve salt optimize cationic exchange. Dispersibility tests showed functionalization deeply change polarities carbon modify compatibility interactions different media, such as polymer matrices.
