In this article, reduced graphene oxide (RGO)/carboxymethyl chitosan (CMC) composites (RGO/CMC) were synthesized by a hydrothermal method through in-situ reduction and modification of graphene oxide (GO) in the presence of CMC. An electrochemical sensor for the determination of Cu(II) by differential pulse anodic stripping voltammetry (DPASV) was constructed by an electrode modified with RGO/CM...
The experimental evaluation of structure formation in solutions individual polymers, as well their mixtures with other polymers order to predict the properties materials obtained on basis was aim this work. We used chitosan, sodium salt chitosan succinyl, carboxymethyl cellulose, and polyvinyl alcohol. Distilled water, 1 % acetic acid, buffer systems based acid acetate pH = 3.80, 4.25, 4.75 wer...
Abstract In recent years, conductive hydrogels, as an ideal flexible material, have quite broad application prospects in various electronics fields, such supercapacitors, batteries, and sensors. However, mechanical stress stretching, fracture, compression will affect the performance of hydrogel during application, which limits its further application. Polysaccharides, cellulose chitosan, are wi...
