Comparison of succinylation methods for bacterial cellulose and adsorption capacities of bacterial cellulose derivatives for Cu2+ ion

Direct sulfation of bacterial cellulose with a ClSO3H/DMF complex and structure characterization of the sulfates

“…Bacterial cellulose (BC) was prepared according the procedure in our previous report . BC gels were washed with running tap water for 24 h to remove the cultural substances on the surface, and then stirred in 1% (w/V) NaOH solution for 24 h at 70°C.…”

“…Chemical modification is a blossoming process to prepare BC derivatives with tailored structure and properties. Several chemical modification methods of BC have been reported, including carboxymethylation, acetylation, phosphorylation, benzoylation, succinylation, silylation, carbanilation, etc. Chemical modification of BC can be carried out both heterogeneously and homogeneously, and generate BC derivatives with diverse degree of substitution.…”

Sustainable succinylation of cellulose in a CO2-based switchable solvent and subsequent Passerini 3-CR and Ugi 4-CR modification

“…Extensive studies are available on the homogenous succinylation of cellulose using succinic anhydride leading to various DS ranging from 0.3 without any catalyst to 2.3 using catalysts such as 4-(dimethylamino)pyridine (DMAP), depending also on the reaction conditions. [23][24][25] A variety of solvent systems and catalysts have been studied for this cellulose modification so far. For instance, Yin et al 25 studied a N,N-dimethylacetamide/LiCl solvent mixture for the succinylation of cellulose in the presence of triethylamine as catalyst, leading to DS values of up to 1.45.…”

Fabrication of a blood compatible composite membrane from chitosan nanoparticles, ethyl cellulose and bacterial cellulose sulfate

“…12 BC is a natural nanobrous membranes, having ultrane reticulated ber structure (3-4 nm (thickness) and 370 AE 80 nm (width)). 13,14 BC has been widely used in blood-contacting materials, such as articial blood vessels, articial skin, and wound healing materials. 15 BC is a good candidate to prepare blood compatible membrane.…”
