Abstract
The present disclosure relates to surface modified nanocrystalline cellulose (NCC) prepared by chemical modification of NCC as well as its use thereof, including as carrier of particular chemical compounds. The surface of nanocrystalline cellulose (NCC) was modified with chitosan oligosaccharide (CSOS) by selectively oxidizing the primary alcohol moieties of NCC followed by coupling of the amino groups of CSOS to the oxidized NCC to provide the desired material (NCC-CSOS).
Claims11
A surface modified nanocrystalline cellulose (NCC) comprising chitosan oligosaccharides (CSOS) covalently bond to the external surface of said NCC (NCC-CSOS).
A method for preparing a surface modified nanocrystalline cellulose (NCC) comprising oxidizing primary hydroxyl groups of said NCC to provide oxidized functional groups and covalently bonding chitosan oligosaccharides (CSOS) to the oxidized functional groups.
