In the present work NiO/ZnO was synthesized from combustion method, polyaniline and the polyaniline based NiO/ZnO using chemical oxidation method. The synthesized materials were characterized using XRD and UV/Vis absorbance spectroscopy. From XRD, the formation of NiO/ZnO was confirmed. The study investigates the applicability of NiO/ZnO Nanocomposite as photo catalyst for the degradation of organic dyes. Results suggested an increase in degradation efficiency in the case of polymer nanocomposite when compared to counter parts.

Conformance control is a major challenge in hydrocarbon recovery operations. One of the effective technologies for improving the conformance of a flood front and modifying the injected fluid profile is the application of polymer hydrogels. In this technique, polymer hydrogels are prepared as gel particles, which are injected into the reservoir to block-off preferential flow paths and thief zones, such as fractures and high permeability zones. Subsequently, the fluid injected as part of oil recovery operation would be directed and forced to pass through low permeable zones and sweep more hydrocarbon mass towards the production wells. Depending on the situation, this technology can result in a considerable incremental hydrocarbon recovery from a reservoir. In the present research, nanotechnology was combined with polymer engineering to develop a novel polymer nanocomposite hydrogel with supreme properties, as confirmed using advanced rheological characterisation. Subsequently, the performance of the newly developed nanocomposite hydrogel was tested using a specially designed core flooding setup and procedure. The core flooding results showed that the application of this novel hydrogel could increase the oil recovery by up to 16% under laboratory conditions.

Nanocomposite hydrogels, made by incorporating nanoparticles into a hydrogel matrix, have been developed to fulfill the need for materials with enhanced and predictable mechanical properties and functionality. This review breaks down the process of preparing and characterizing nanocomposite hydrogels and looks at the various applications they can be used for. Through careful selection of the nanoparticle and hydrogel types, as well as the preparation method, the degree of crosslinking and the strength of the intermolecular interactions between the nanoparticles and the hydrogel matrix can be controlled. Once the nanomaterial is prepared, the morphology, gel content, thermal stability, and mechanical properties are investigated. By varying the concentrations of nanoparticles within the hydrogel matrix, nanocomposite hydrogels with optimal functionality and mechanical properties are produced. The optimized nanomaterial can then be used for its intended application(s); here the focus is on applications in the biomedical and dye adsorption fields. With further research, it is predicted that nanocomposite hydrogels will fulfill their potential to be used in practical, everyday applications.
