Abstract
An efficient method for covalently linking of cellulose and clay using a click chemistry based strategy is reported. Azide and alkynyl derivatives of silane were synthesized and used for silanization of cellulose and clay respectively. Functionalized cellulose and clay were then coupled using Cu(I) catalyzed azide–alkyne cycloaddition reaction, resulting in a covalent linkage between them. Successful synthesis of the silane derivates was established using Fourier transform infrared (FTIR) and nuclear magnetic resonance. Silanization of cellulose and clay with azide and alkynyl derivatives and the formation of a triazole linkage were confirmed using FTIR.
