“…The polymer PDADMA is selected because of its low cost (about 25% of CTMA) and commercial availability. It has also been used to intercalate montmorillonite (Churchman, 2002;Ganigar et al, 2010;Shen et al, 2009;Souza and Nascimento, 2008). The structural characteristics of the CTMA and PDADMA synthesized organo montmorillonites (C/P-Mt) will be investigated, and their sorptive characteristics towards phenol will also be examined.…”

“…Depending on their polarity and the type of clay counter ion, certain molecules may penetrate the interlayer galleries, resulting in significant swelling [2][3][4][5]. Such molecules range from low molar mass compounds, such as water [6,7], volatile organic species [8][9][10][11][12][13], and non-volatile low molecular mass species [14,15], to macromolecules [16][17][18].…”

Desorption isotherms for water, ethanol, ethyl acetate and toluene from a sodium smectite clay have been determined by both dynamic vapor sorption (DVS) measurements and Knudsen thermogravimetry (KTGA), at the exception of toluene that was measured only by the DVS method. The results obtained using these two methods were in satisfactory agreement, providing reliable insight into the desorption process, with certain lack of precision for ethyl acetate. The observed desorption behaviour suggests a liquid like phase at high volatile load, and a sorbed state in which molecules interact with the counter ions, at low volatile contents. However, the isotherms for water determined at various temperatures nearly superposed when plotted as a function of water activity, indicating the strength of the interactions in the clay-water system to remain of the same order of magnitude as that in bulk water, consistent with previous ab initio calculations.

Based on the requirement of the synthesized polymer resistant to higher temperature and lower cost demand of water-based drilling fluid system, a novel polymer, which named poly(AMPS/AM/SSS), was synthesized using acrylamide (AM), 2-acrylamido-2methylpropanesulfonic acid (AMPS), and p-styrenesulfonate (SSS). At first, the molecular structure was investigated through Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance hydrogen spectroscopy ( 1 H-NMR) and element analysis. Simultaneously, the molecular weight and distribution was obtained by gel chromatography method. Moreover, the thermal stability was produced by thermal analysis (TG). Secondly, the poly(AMPS/AM/SSS) was introduced into water-based drilling fluid system. As a result, it was shown that the use of poly(AMPS/AM/SSS) significantly improved the filtration performance of drilling fluid system. When the adding amount is 1.2 wt %, the FL API of drilling fluid system is 9.20 mL. Moreover, it was found that the flow curve of water-based drilling fluid systems are more fitted to the Herschel-Bulkley flow model. Besides, the temperature resistance of water-based drilling fluid system was obviously improved. Furthermore, it was confirmed that the cost of water-based drilling fluid system was significantly reduced. During this study, the filtration mechanism of the synthesized poly(AMPS/AM/SSS) was studied by adsorption analysis, Zeta potential method, and morphology analysis.
