METHODS FOR BIODEGRADABLE DERIVATIZATION OF CELLULOSIC SURFACES

A solid cellulose-containing material having a surface and comprising hydroxyl groups on the surface， wherein at least a portion of the oxygen atoms contained in the hydroxyl groups available on the surface are attached directly via an ester bond to a carbon atom of an acyl group of an alkanoic acid derivative having the formula (I) or formula (II): ???????????????? R-CO-X??????????Formula (I)， ???????????????? X-CO-R-CO-X 1??????????Formula (II)， wherein R is a straight-chain， branched-chain， or cyclic aliphatic hydrocarbon radical having from 6 to 50 carbon atoms， and wherein X and X 1 are independently Cl， Br， or O(CO)OR， and wherein the surface exhibits a water contact angle of between 60° to about 120°.
