Abstract:
A hydrogel is a water-insoluble three-dimensional polymer network that has the ability to absorb body fluids in a biological environment. Such a polymer network is formed through chemical crosslinking mechanisms such as optical polymerization, enzymatic reactions and physical crosslinking such as temperature and pH dependent processes and ionic crosslinking. Physical hydrogels are formed through weak secondary force and chemical hydrogels are formed by covalent forces. Various polymers of natural and synthetic origin are used to make hydrogels.

In this study, nanocomposite hydrogels were prepared by embedding the different concentrations of TiO2 nanoparticles (NPs) in a poly(N-isopropylacrylamide) (PNiPAAm) crosslinked matrix. UV- Vis and FTIR spectroscopy have been employed to determine the presence of TiO2 NPs in the polymer network and examine their molecular interactions, respectively. The TiO2/PNiPAAm nanocomposite hydrogels showed a slightly higher swelling capacity and a faster swelling/deswelling processes compared to PNiPAAm hydrogel. Additionally, the volume phase transition temperature of nanocomposites is shifted towards

Abstract:
Abstract Hydrogel polymers have served the oil and gas industry in different applications including water shot-off. Hydrogel polymers can create impermeable gels to optimize water injection profile, improve sweep efficiency, and seal undesirable permeable zones. They have been successfully applied as remediation treatments to control water production from thief zones, natural fractures, and matrix formation. In this study, a new hydrogel polymer system (HGPS) was examined for water control treatments in sandstone formations. The experimental work included swelling testing, viscosity measuremen

Abstract:
Due to its potential to provide sustainable solutions to pollution and contamination, photocatalysis is a promising area of research in the fields of environmental protection and water remediation. The main objective of this work was to prepare an environmentally friendly, durable, easily-separable, and reusable nanocomposite hydrogel with g-C3N4 encapsulated into a carboxymethylcellulose (CMC) and sodium alginate (SA) polymer matrix for wastewater remediation. The physicochemical properties of the prepared hydrogel were characterized by FE-SEM and ATR-FTIR spectroscopy. The g-C3N4/CMC/SA hydr

Condensation and moisture buildup in the automotive headlamp decrease the visibility to the driver. The super hydrophilic cross-linked polymer composites were prepared with the combination of polyacrylamide-based hydrogels and hygroscopic lithium bromide desiccants. In this work, we have utilized various desiccants such as calcium chloride (

Abstract:
A drug-loaded conductive polymer/hydrogel blend, benzoic acid-loaded poly(3,4-ethylenedioxythiophene/alginate (BA-loaded PEDOT/Alg) hydrogel, was used as a carrier/matrix for an electrical stimuli transdermal drug delivery system (TDDS). The effects of crosslinking ratio, PEDOT particle size, and electric field strength on the release mechanism and the diffusion coefficient (D) of BA were examined by using a modified Franz-diffusion cell. The diffusion scaling exponent value of BA is close to 0.5 which refers to the diffusion controlled mechanism, or the Fickian diffusion as the BA release mec
