Functionalization of Cellulose: Synthesis of Water-soluble Cationic Cellulose Derivatives
One of the trends of modern cellulose chemistry is the functionalization of known cellulose derivatives in order to expand their application area. In this work, water-soluble cationic cellulose derivatives containing up to 4% coupled nitrogen were obtained by the amination of hydroxyethylcellulose (HEC) with two different etherification agents, diethylepoxypropylamine (DEEPA) and (2-chlorethyl)...
متن کاملSynthesis of new bis(acyl)phosphane oxide photoinitiators for the surface functionalization of cellulose nanocrystals.
A new synthesis of bis(acyl)phosphane oxide (BAPO) photoinitiators was developed which can be used to functionalize cellulose nanocrystal surfaces for polymer grafting. Hybrid materials with excellent graft yields can be rapidly obtained under mild and acid-free conditions.
متن کاملFunctionalization of Cellulose Nanocrystals in Choline Lactate Ionic Liquid
Cellulose nanocrystals (CNCs) are valuable nanomaterials obtained from renewable resources. Their properties make them suitable for a wide range of applications, including polymer reinforcement. However, due to their highly hydrophilic character, it is necessary to modify their surface with non-polar functional groups before their incorporation into a hydrophobic polymer matrix. In this work, c...
متن کاملA facile one-pot route to cationic cellulose nanocrystals.
Pyridinium-grafted-cellulose nanocrystals were prepared by a simple one-pot reaction using 4-(1-bromoethyl/bromomethyl)benzoic acid, pyridine and cellulose nanocrystals (CNCs). The grafting consists of an esterification reaction between 4-(1-bromoethyl/bromomethyl)benzoic acid and CNCs and a nucleophilic attack on the C-Br bond of 4-(1-bromoethyl/bromomethyl)benzoic acid by pyridine. This react...
متن کاملCellulose nanocrystals with tunable surface charge for nanomedicine.
Crystalline nanoparticles of cellulose exhibit attractive properties as nanoscale carriers for bioactive molecules in nanobiotechnology and nanomedicine. For applications in imaging and drug delivery, surface charge is one of the most important factors affecting the performance of nanocarriers. However, current methods of preparation offer little flexibility for controlling the surface charge o...
