“…In the last few years the combination between bentonite with other materials such as metal oxide, polymers, and natural polymers has received a great deal of attention (Srinivasan, 2011;Dukic et al, 2015;Ianchis et al, 2015;Rzayev et al, 2015;Vanamudan and Pamidimukkala, 2015). Many of those composites were used as ecofriendly and efficient adsorbent for removal of organic, inorganic, and pathogenic contaminants from water and wastewater (Srinivasan, 2011), however, the main drawback for the application of those composites as adsorbent in real water or wastewater system is in the production cost of the composite.…”

“…The bands for the CH stretching (aliphatic) and ester groups at 2985 and 1200 cm −1 , respectively, were contributed to the grafted PLA units [Figure (b)]. Additionally, the bands at 1171, 1039, and 924‐cm −1 confirmed the SiOSi vibrations and SiO stretching from the delamination of the clay mineral layers [Figure (b)] . The peak at 1050 cm −1 confirmed the stretching and bending modes of the SiOSi groups [Figure (b)] .…”

In this study, we developed a new approach for the fabrication of a green poly(L-lactic acid)-grafted starch (St-g-PLA) copolymer and nanocomposite (St-g-PLA/organoclay)-based films via shear-mixing and reactive-extrusion systems. The chemical and physical structures, thermal behavior, and morphology of the synthesized blends and some other parameters were examined by Fourier transform infrared spectroscopy and 13 C cross-polarization/magic angle spinning NMR spectroscopy, X-ray diffraction, thermogravimetric analysis-derivative thermogravimetry, and scanning electron microscopy, respectively. Significant increases in the mechanical and permeability properties were evident in the high value of grafted poly(lactic acid) molar percentages and high exfoliation of organoclay. The biodegradability of films were investigated under aerobic composting conditions through the measurement of the temperature, moisture, pH, consumed O 2 value, and carbon dioxide produced. This new strategy mainly improved the good adhesion between both phases, and it was an interesting method for the production of environmentally friendly biocomposites that could easily be scaled up for commercial production with the potential for replacing petroleum-based plastics.

“…However, the thermoresponse of the composite hydrogel was not reported [12]. In addition, a novel octadecyl amine–(ODA–Mt) copolymer nanocomposite was synthesized for bioengineering by modifying the montmorillonite with N-isopropylacrylamide (NIPAM) polymers [13]. In this research, the heating method is demonstrated to be a facile and highly effective technique for clay polymer nanocomposites (CPNs) that provides a higher rate of copolymerization and conversion of micro- and nanoparticles [14].…”

As an important industrial material, bentonite has been widely applied in water-based drilling fluids to create mud cakes to protect boreholes. However, the common mud cake is porous, and it is difficult to reduce the filtration of a drilling fluid at high temperature. Therefore, this paper endowed bentonite with a thermo response via the insertion of N-isopropylacrylamide (NIPAM) monomers. The interaction between NIPAM monomers and bentonite was investigated via Fourier infrared spectroscopy (FTIR), isothermal adsorption, and X-ray diffraction (XRD) at various temperatures. The results demonstrate that chemical adsorption is involved in the adsorption process of NIPAM monomers on bentonite, and the adsorption of NIPAM monomers accords with the D–R model. With increasing temperature, more adsorption water was squeezed out of the composite when the temperature of the composite exceeded 70 °C. Based on the composite of NIPAM and bentonite, a mud cake was prepared using low-viscosity polyanionic cellulose (Lv-PAC) and initiator potassium peroxydisulfate (KPS). The change in the plugging of the mud cake was investigated via environmental scanning electron microscopy (ESEM), contact angle testing, filtration experiments, and linear expansion of the shale at various temperatures. In the plugging of the mud cake, a self-recovery behavior was observed with increasing temperature, and resistance was observed at 110 °C. The rheology of the drilling fluid was stable in the alterative temperature zone (70–110 °C). Based on the high resistance of the basic drilling fluid, a high-density drilling fluid (ρ = 2.0 g/cm3) was prepared with weighting materials with the objective of drilling high-temperature formations. By using a high-density drilling fluid, the hydration expansion of shale was reduced by half at 110 °C in comparison with common bentonite drilling fluid. In addition, the rheology of the high-density drilling fluid tended to be stable, and a self-recovery behavior was observed.
