Environmental pollution from organic contaminants caused by textile dyeing is a real danger. Wastewater the industry has high loads, as well dyes and chemical compounds used in their preparation. Among azo dyes, Congo red (CR) dye widely model experimental studies of wastewater treatment. Heterogeneous photocatalysis consists UV or VIS light irradiation various types water presence solid cataly...

Silicon anodes require polymer binder systems that are both mechanically robust and electrochemically stable, to accommodate the dramatic volume expansion experienced during cycling operation. Herein, we report use of a poly(acrylic acid)-grafted styrene–butadiene rubber (PAA-g-SBR) with 80% partially neutralized Na-PAA as system for silicon-graphite anodes. The PAA-g-SBR graft copolymer was sy...

Scars are consequences of the wound healing process, and eliminating scar formation remains a significant challenge. Here, an injectable HMSC hydrogel was developed based on silk fibroin peptide grafted hydroxypropyl chitosan (HPCS-g-SFP) oxidized microcrystalline cellulose (OMCC) via Schiff base bonds. The synthesized HPCS-g-SFP copolymer displayed efficient free radical scavenging ability hyd...

An iodide-terminated polymer (Polymer-I) is converted to a thiol-terminated (Polymer-SH) using HSCH2CH2SH in remarkably short time (10 min). Polymer-SH further pyridyl disulfide-terminated (Polymer-SS-Py). The hetero-coupling of and Polymer-SS-Py successfully achieved quantitatively generate disulfide (Polymer-SS-Polymer). Exploiting this efficient technique, attached (grafted) on Py-SS-immobil...

The presence of polymer chains grafted or adsorbed onto a surface can dramatically alter the forces that affect interactions between surfaces. The equilibrium properties of such polymer brush systems have been studied for the past two decades, yielding general agreement between theory and experiment. Conversely, the nonequilibrium properties of polymer brushes are still under intense theoretica...

Phthalocyanine pigments have many problems in waterborne coating applications because of their low polarity, poor dispersion water, and easy agglomeration properties. In order to solve these problems, the phthalocyanine were encapsulated with a copolymer methyl methacrylate (MMA) butyl acrylate (BA) by mini-emulsion polymerization method. The are effectively dispersed water good compatibility r...

epoxy – polysulfide copolymers without or with low amounts of epoxy in their structure have poor mechanical properties in oxidative curing system.to strengthen the mechanical properties of polysulfide elastomer inclusion of epoxy resin (epon828) as hard segment was studied. ft-ir spectroscopy and rheometry were used to verify the formation of epoxy-polysulfide copolymer.  results obtained from ...
