This study examines the efficacy of xanthan gum, as a natural polymer, in creating suitable hydrogel for controlling water production reservoirs. The employed Central Composite Design (CCD) method through bottle tests to evaluate effect different compounds on gelation time and duration syneresis. To explore effectiveness xanthan-based hydrogels, swelling well dynamic core flooding are performed. Additionally, enlighten performance comprehensive set characterization Nevertheless, test results indicated that increasing polymer concentration led an increase swelling. SEM images dried confirmed structural integrity uniformity networked architecture, demonstrating thickness density.

There is ongoing research for biomedical applications of polyvinyl alcohol (PVA)-based hydrogels; however, the execution this has not yet been achieved at an appropriate level commercialization. Advanced perception necessary design and synthesis suitable materials, such as PVA-based hydrogel applications. Among polymers, drawn great interest in owing to their attractive potential with characteristics good biocompatibility, mechanical strength, apposite water content. By designing approach investigating structure, hydrogels can attain superb cytocompatibility, flexibility, antimicrobial activities, signifying that it a candidate tissue engineering regenerative medicine, drug delivery, wound dressing, contact lenses, other fields. In review, we highlight current progresses on explaining diverse usage across variety areas. We explain numerous techniques related phenomena based these materials. This review may stipulate wide reference future acumens materials extensive
