“…Above UCST, the dipolar interactions are broken and the isolated polymer chains are completely solvated. In other words, the high-viscosity gel is transformed into a transparent low-viscosity sol above UCST [75]. The most studied and applied polymer possessing UCST in an aqueous solution is polysulfobetaine poly(38) depicted in Figure 5a and its UCST is highly dependent on pressure, type of polymer and its molecular mass characteristics as well as on the single electrolyte presence.…”

“…Moreover, changing the monomer character by the introduction of a backbone moiety such as styrene poly (40) [93], or imidazole-based poly (44) [75,94] or changing the distance of the charged moieties within the polymer backbone can result in polymeric materials with a variability of UCST. It should be noted that the polymers with styrene moieties in the backbone prevent any hydrolytic cleavage of the ester or amide groups in the backbone, which can occur in methacrylic-type polymers [95].…”

Abstract:In recent decades, the design and construction of smart materials capable of switching into a polyzwitterionic state by an external trigger have been intensively pursued. Polyzwitterionic states have unique antifouling and surface properties and external triggers, such as pH, light, ions, electric field and CO 2 , cause significant changes in materials with regard to overall charge, ionic strength and wettability. This survey highlights current progress in the irreversible as well as the reversible switching process involving polyzwitterionic moieties, which can, in turn, be applied to studying the interaction of various interfaces with biological species as protein, DNA, bacteria or platelets and also for advanced use.

“…Due to the performance boundary for the conventional materials, stimuli‐responsive materials can be potentially utilized in the field of CO 2 ‐EOR based on the distinct environmental changes . Temperature‐responsive polymer (TRP) is currently one of the largest classes in oilfield‐utilized smart additives lies foremost in the mastery of objective environment . Zwitterionic TRPs featuring an upper critical solution temperature (UCST) exhibit a heat‐elevated hydrophilicity as the interelectrostatic and intraelectrostatic association would be broken within the positively and negatively charged moieties .…”

CO2 has been widely used in the process of enhanced oil recovery (EOR) over decades. However, the heterogeneity of oil reservoirs renders CO2 to flow preferentially into highly permeable zones, leaving tight areas unswept with oil unrecovered in these areas. While conventional water‐swelling gels were used for blocking the “channeling” path, most of them experience the risks of shrinkage under high temperature and CO2‐induced acidic environment. Here, we developed double swelling smart polymer microgels (SPMs) triggered by both heat and CO2. Such SPMs were prepared by copolymerization of acrylamide (AAm) in combination with N,N‐2‐(dimethylamino)ethyl methacrylate (DMAEMA) and [2‐(methacryloyloxy) ethyl]dimethyl‐(3‐sulfopropyl) ammonium hydroxide (SBMA), and with N,N′‐methylene bisacrylamide (MBA) as the crosslinker. These SPMs swell when temperature is higher than 65 °C or in the presence of CO2, with an ameliorative salinity tolerance ability. Artificial sand pack flooding carried by SMPs at 65 °C showed an elevated plugging efficiency at around 97% under a simulated pressurization at 5 MPa, proposing a valid candidate for future EOR applications during CO2 flooding. © 2019 Wiley Periodicals, Inc.

Water‐soluble polymers (WSPs) represent a diverse class of macromolecules, and this diversity arises from the breadth of functionality derived from both natural and synthetic sources. Nature provides abundant WSPs through biosynthetic pathways in plants, animals, and fungi, and biological processes yield precisely controlled and well‐defined structures. Polymer chemists strive to develop synthetic methods that mimic the precision of natural processes. Monomers that are derived from petroleum feedstocks together with naturally sourced monomers provide a rich catalog of WSP precursors. Monomer structure, reactivity, concentration, sequence control, and reaction conditions influence polymeric microstructures, solubility, and aqueous solution structure. This article provides an overview of WSP fundamentals and highlights recent advancements in natural, nonionic, ionic, associative, and high‐performance WSPs. Recent advances in the design and performance of WSPs have critically improved the technological impact of filtration processes, water purification, drilling efficiency, and pharmaceutical applications. From modulating the rheological and filtration properties to establishing novel drug delivery systems through controllable self‐assembly, WSPs represent a critical enabling field for many emerging and diverse applications. WSPs will help to address many of the emerging challenges of our times, from energy generation and storage to water availability and next‐generation life‐saving medical technologies. This article will point to the potential impacts based on fundamental structure‐property‐processing relationships.
