Development of ionic liquid-mediated antibacterial cellulose-chitosan films was written by Zhou, Yonghui;Luo, Xiaolin;Huang, Liulian;Lin, Shan;Chen, Lihui. And the article was included in Journal of Biobased Materials and Bioenergy in 2015.HPLC of Formula: 35487-17-3 This article mentions the following:
The solubility of cellulose, chitosan and their composites has been investigated to understand their roles in the formulation of antibacterial cellulose-chitosan composite films and their contributions to the performance of the films. Antibacterial and homogeneous cellulose-chitosan composite films with high mech. property were successfully prepared by co-dissolving cellulose and chitosan in 1-ethyl-3-methylimidazolium acetate (EmimAc) ionic liquid The composite films were further characterized by using XRD, TGA, FTIR, SEM, mech. strength and antibacterial ability measurements. XRD anal. of the films suggested that the structure of crystalline as well as crystallinities of both polymers changed during the processes of dissolution and regeneration, although their solubility varies considerably. The developed films were thermally more stable than the regenerated cellulose or chitosan itself. Hydrogen bonding between cellulose and chitosan in the blend films was determined by FTIR. SEM images also revealed a homogeneous and compact structure of the blend films. In addition, cellulose-chitosan composite films showed highly inhibitory effects on the bacteria of E. coli. and S. aureus. In the experiment, the researchers used many compounds, for example, 1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3HPLC of Formula: 35487-17-3).
1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.HPLC of Formula: 35487-17-3
