“…It was revealed that the multiphase hybrid filler was able to preserve as well as showed process synergising effect in polymers and elastomers due to the compatibility and co‐operative interactions at the nanoscale. For example, Hybrid filler systems containing CB and carbon nanotube (CNT) ,CB and nanoclay and CB and nanographene/graphene oxide were developed and the resulting rubber nanocomposites demonstrated remarkable improvement in properties taken for their studies.…”

In this work, nitrile rubber (NBR) conventional composites containing 70 phr carbon black (CB) is taken for study. New NBR hybrid composites containing 60 phr of CB and varied halloysite nanotube (HNT) loading of 2, 4, 6, 8, and 10 phr were developed. Experimental investigations were carried out to study the synergistic effect of CB and HNT on the dynamical mechanical properties, solvent resistance, thermal stability and degradation kinetics of NBR hybrid composites. Morphological analysis using X‐ray diffraction analysis (XRD) and Field emission scanning electron microscopy (FESEM) revealed the presence of intercalated structures and formation of local CB‐HNT filler network in the NBR matrix. The glass transition temperatures (Tg) of hybrid composites were raised with the addition of HNT which indicates strong interfacial adhesion between NBR–CB–HNT. Dynamic mechanical analysis and solvent uptake studies revealed that replacement of 10 phr CB by 6 phr HNT in hybrid composites improved the storage modulus by 44% at 30°C and solvent resistance by 29%, respectively. Most importantly, the incorporation of HNT could effectively improve the thermal stability of the NBR hybrid composites according to thermogravimetric analysis and oxidation induction time studies. The activation energy of the thermal decomposition of the hybrid composites increased with the addition of HNT. POLYM. COMPOS., 40:E1612–E1621, 2019. © 2018 Society of Plastics Engineers

Rubber nanocomposites containing one type of nanofiller are common and are widely established in the research field. In this study, nitrile rubber (NBR) based ternary nanocomposites containing modified silicate (Cloisite 30B) and also nano-calcium carbonate (nano-CaCO 3 ) were prepared using a laboratory internal mixer (simple melt mixing). Effects of the hybrid filler system (filler phase have two kind of fillers) on the cure rheometry, morphology, swelling, and mechanical and dynamic-mechanical properties of the NBR were investigated. Concentration of nano-CaCO 3 [0, 5, 10, and 15 parts per one hundred parts of rubber by weight (phr)] and organoclay (0, 3, and 6 phr) in NBR was varied. The microstructure and homogeneity of the compounds were confirmed by studying the dispersion of nanoparticles in NBR via X-ray diffraction and field emission scanning electron microscopy. Based on the results of morphology and mechanical properties, the dual-filler phase nanocomposites (hybrid nanocomposite) have higher performance in comparison with single-filler phase nanocomposites.

“…Hence, these FT-IR peaks suggest the successful development of WR-PPG. Furthermore, small shifts in the FT-IR peaks for NR-PPG as compared to WR-PPG have been noticed possibly due to the reinforcement of the titanium dioxide (TiO 2 ) nanomaterial in the developed polymer matrix of NR-PPG. , …”

This current research article aims to fabricate a novel reinforced preformed particle gel to increase oil production and reduce excessive water production. To achieve this objective, the following synthesis procedure was adopted. At the start, the preformed particle gel (PPG) samples were developed with N,Ndimethylacrylamide, acrylic acid, and AMPS as a monomer, and N,Nmethylenebisacrylamide was used as a cross-linker. The TiO 2 nanomaterial was used as a reinforcing agent to enhance the strength characteristics of PPGs by the free radical polymerization mechanism. To characterize the developed samples, i.e., without reinforced preformed particle gel (WR-PPG) and 0.30 wt % titanium dioxide nanomaterial-reinforced preformed particle gel (NR-PPG), the FT-IR spectra, PXRD, FESEM, EDX, and TGA DTG DSC analytical techniques were used. The developed NR-PPG can absorb distilled water and brine (30 000 ppm) up to 95 and 21 times its dry weight, respectively. Furthermore, a complete evaluation of the swelling behavior was performed using several variable parameters such as salinity, pH, temperature, nanomaterial concentration, and monovalent and multivalent ions. The rheology test confirms the formation of the 3d structure and the toughness modulus (G′) of NR-PPG, i.e., 1168 and 2085 Pa, and WR-PPG, i.e., 980 and 1334 Pa, for distilled water and 30 000 ppm brine solution, respectively. Additionally, the long-term temperature stability test of NR-PPG revealed outstanding thermal stability for 130 days at 120 °C in a brine solution containing 30 000 ppm NaCl. Finally, the core flooding test was used to evaluate the performance of NR-PPG and WR-PPG for the application of water shutoff jobs, and the plugging efficiency of 94−97 and 89−95% in terms of permeability reduction was observed for NR-PPG and WR-PPG, respectively. As a result, the newly synthesized novel NR-PPG may improve water shutoff and oil recovery in mature oil fields.
