An ionic liquid as reaction media for radiation-induced grafting of thermosensitive poly (N-isopropylacrylamide) onto microcrystalline cellulose

Cytotoxicity and biocompatibility evaluation of a poly(magnesium acrylate) hydrogel synthesized for drug delivery

“…Regarding toxicity most of the problems associated with hydrogel carriers depend on the unreacted monomers, oligomers and other chemical agents (reticulating or catalyzing agents) that leach out during application. Several studies have evaluated the formation of hydrogels with less chemical agents in order to eliminate the problem of residual chemicals which could compromise biocompatibility (Peppas et al, 1999;Hao et al, 2009;Rivarola et al, 2009). In our case, hydrogels of PAMgA were synthesized by thermal polymerization without the presence of a catalyzing agent.…”

Adsorption of Reactive blue 21 onto functionalized cellulose under ultrasonic pretreatment: Kinetic and equilibrium study

“…3. The crystalline peaks cellulose at 2θ = 16.18 and 22.6 are characteristic of cellulose I crystal [22]. After the modification, the characteristic peaks disappeared and new peaks occurred, which proved that the hydrogen bonds in FS cellulose (curve (a)) were broken in MCFS cellulose (curve (b)).…”

Functionalization of Microcrystalline Cellulose with N,N-dimethyldodecylamine for the Removal of Congo Red Dye from an Aqueous Solution

“…2(d). The XRD pattern of MCC shows a typical cellulose I structure, with a sharp peak at 22.74, a wide peak between 14.26 and 17.16, and a typical peak at 34.56 (Hao et al 2009). However, these characteristic peaks either disappeared or were weakened in the XRD pattern of FM-1.…”
