Worldwide, reservoirs are having serious challenges on crude oil removal due to various factors affecting its mobility; hence, the approach of production needs be rectified. Recently, nanoparticles (NPs) were discovered have aided in displacement improve by modifying some reservoir conditions thereby reducing interfacial tension (IFT) and rock surface wettability. However, injected NPs trapped within pores become worthless high temperature pressure. Hence, introducing energy nanofluids via...
In this research, nanocomposite solid polymer electrolytes (NCSPEs) comprising methylcellulose/pectin (MC/PC) blend as host polymer, ammonium chloride (NH4Cl) an ion source, and zinc oxide nanoparticles (ZnO NPs) nanofillers were synthesized via a solution cast methodology. Techniques such Fourier transform infrared (FTIR), electrical impedance spectroscopy (EIS), linear sweep voltammetry (LSV) employed to characterize the electrolyte. FTIR confirmed that polymers, NH4Cl salt, ZnO nanofiller...
Composite polymer electrolyte (CPE) based on polyvinyl alcohol (PVA) polymer, potassium carbonate (K2CO3) salt, and silica (SiO2) filler was investigated optimized in this study for improved ionic conductivity potential window use electrochemical devices. Various quantities of SiO2 wt.% were incorporated into PVA-K2CO3 complex to prepare the CPEs. To effect composites, developed electrolytes characterized their chemical structure (FTIR), morphology (FESEM), thermal stabilities (TGA), glass...
The increased interest in the transition from liquid to solid polymer electrolytes (SPEs) has driven enormous research area electrolyte technology. Solid biopolymer (SBEs) are a special class of SPEs that obtained natural polymers. Recently, SBEs have been generating much attention because they simple, inexpensive, and environmentally friendly. In this work, based on glycerol-plasticized methylcellulose/pectin/potassium phosphate (MC/PC/K3PO4) investigated for their potential application an...
In this study, a solution casting method was used to prepare solid polymer electrolytes (SPEs) based on blend comprising polyvinyl alcohol (PVA), cellulose acetate (CA), and potassium carbonate (K2CO3) as conducting salt, zinc oxide nanoparticles (ZnO-NPs) nanofiller. The prepared were physicochemically electrochemically characterized, their semi-crystalline nature established using XRD FESEM. addition of ZnO the polymer-salt combination resulted in substantial increase ionic conductivity,...
Abstract Electrospun fiber membrane as a separator‐electrolyte have been prepared in this study using electrospinning process from cellulose acetate, PVA, K 2 CO 3 , and SiO with different concentrations. Five concentration were (14–22 wt%) mixture of dimethyl sulfoxide acetone fixed ratio 2:3. The electrospun membranes characterized shown to exhibit good well‐structured morphology formed by interlaying fibers, where the thinnest finest fibers achieved at 20 wt% polymer concentration,...
The interaction of nanoparticles (NPs) with crude oil in a porous media activated by electromagnetic (EM) waves is projected to be crucial approach reduce interfacial tension (IFT) for the achievement productivity. Various NPs were reported have been used reservoirs and found IFT between fluids oil. However, undergo persistent problem perpetual detachment at fluids/oil interface caused high temperature reservoir which renders inactive. Hence, need increase their task accomplishment higher...
In this research, innovative green and sustainable solid polymer electrolytes (SPEs) based on plasticized methylcellulose/polyvinyl pyrrolidone/potassium carbonate (MC/PVP/K2CO3) were examined. The MC/PVP/K2CO3 SPE system with five distinct ethylene (EC) concentrations as a plasticizer was successfully designed. Frequency-dependent conductivity plots used to investigate the conduction mechanism of SPEs. Electrochemical potential window stability cation transfer number SPEs studied via linear...
