On the para/ortho reactivity of isocyanate groups during the carbamation of cellulose nanocrystals using 2, 4-toluene diisocyanate
(Multidisciplinary Digital Publishing Institute, 2019-09)2,4-toluene diisocyanate (TDI) has been commonly used to bind molecules and polymers onto the surface of cellulose nanocrystals (CNCs). Such a process usually involves two steps: (1) the more reactive para-isocyanates ... -
A simple method for the quantification of free isocyanates on the surface of cellulose nanocrystals upon carbamation using toluene diisocyanate
(Multidisciplinary Digital Publishing Institute, 2019-06)In many reports, cellulose and nanocellulose have been carbamated using 2,4-toluene diisocyanate (2,4-TDI) to allow the grafting of molecules or polymers onto their surfaces. Such a process usually involves the reaction ...
