Abstract Conductive hydrogels have emerged as fascinating materials for flexible electronics because of their integrated conductivity, mechanical flexibility, and the possibility to introduce several smart functions. However, swelling in aqueous environments significantly reduces applicability where contact with water is unavoidable. In this study, a physically cross‐linked composite hydrogel proposed, that transparent, highly stretchable, anti‐swelling, capable autonomous self‐healing,...
Zwitterionic conductive hydrogels have shown potential application in wearable strain and pressure sensors. However, there are still fundamental challenges to achieve zwitterionic with excellent mechanical properties, able keep flexibility at sub-zero temperatures. To overcome these limitations, a hydrogel was fabricated this work by in-situ polymerization of aniline (ANI) monomer copolymer sulfobetaine methacrylate (SBMA) acrylic acid (AA) matrix. The obtained possesses outstanding...
Atomic transfer radical polymerization (ATRP) of acrylamide has been accomplished in aqueous media at room temperature. By using methyl 2-chloropropionate (MeClPr) as the initiator and tris[2-(dimethylamino)ethyl]amine (Me6TREN)/copper halogenide (CuX) catalyst system, different linear polyacrylamides with apparent molecular weights up to >150 000 g/mol were synthesized dispersities low 1.39. The agreed well theoretical ones relatively low-medium monomer/initiator ratios (<700:1). Initial...
ABSTRACT With the purpose of investigating new potential candidates for enhanced oil recovery (EOR), amphiphilic copolymers based on Poly(ethylene glycol) methyl ether acrylate (PEGA) have been prepared by Atom Transfer Radical Polymerization (ATRP). A P(PEGA) homopolymer, a block copolymer with styrene PS‐ b ‐P(PEGA), and an analogous terpolymer including also sodium methacrylate (MANa) in poly(PEGA) (PPEGA) block, ‐P(PEGA‐ co ‐MANa) characterized. Viscosity surface activity solutions...
During the past half-century, prefix “nano” attached to several words, such as “technology”, “motors”, “device”, and so on has denoted cutting-edge research fields topics at forefront of classical scientific disciplines. Possible application have been frequently evoked, even if real-life examples are still difficult find. The present review analyzes how nanotechnology is utilized in enhanced oil recovery (EOR) processes increase efficiency mature oilfields. Nanotechnology EOR classified into...
Polymers crosslinked via furan/maleimide thermo-reversible chemistry have been extensively explored as reprocessable and self-healing thermosets elastomers. For such applications, it is important that the features are reproducible after many reprocessing healing cycles. Therefore, side reactions undesirable. However, we noticed irreversible changes in mechanical properties of materials when exposing them to temperatures around 150 °C. In this work, study whether these due self-reaction...
Abstract Micro‐nano‐fabrication on objects with complex surfaces is essential for the development of technologies in growing fields flexible electronics and photonics. Various strategies are devised to extend fabrication from conventional planar substrates curved ones, however, significant challenges still exist, especially framework 3D printing additive manufacturing. In this study, a novel technique presented realize micro‐structures arbitrary providing an extreme level conformability....
Starch is one of the best candidates to replace non-renewable plastics thanks its plentiful availability in nature, and low cost. Food industry produces large amount starch-containing waste, which are not utilizable as nutrients, therefore have potential for non-food applications. However, some physicochemical characteristics starch, such thermal stability high hydrophilicity undesirable many Supercritical CO2 an attractive alternative media chemical modification starch due unique tuneable...
A kinetic study of the esterification reaction citric (CA) acid and butyl glycol (BG) with without catalyst was performed to elucidate mechanism. Interestingly, different preferences sites on CA molecules (at α or β position) can be found in either bulk conditions organic solvents. The density functional theory (DFT) model used support this experimental study. Additionally, optimal for regioselectivity toward primary secondary alcohols, presence scandium triflate as catalyst, were studied....
Three well-defined polystyrene–poly(sodium methacrylate) amphiphilic block copolymers characterized by different molecular architecture (diblock, triblock, and four-arm star) have been synthesized ATRP. The rheology of their water solutions has evaluated measuring dynamic moduli shear viscosity at concentrations. All polymers show remarkable thickening properties a sol–gel transition low concentration (0.1 wt %). Above the gel are thinning without an apparent Newtonian plateau. observed...
Diels-Alder chemistry has been used for the thermoreversible cross-linking of furan-functionalized ethylene/propylene (EPM) and ethylene/vinyl acetate (EVM) rubbers. Both elastomers were successfully cross-linked with bismaleimide to yield products a similar cross-link density. NMR relaxometry SAXS measurements both show that apolar EPM-g-furan precursor contains phase-separated polar clusters occurs in these clusters. The heterogeneously network contrasts homogeneous EVM-g-furan....

In the present study performance of a series star-like branched polyacrylamides (SB-PAMs) has been investigated in oil recovery experiments to ultimately determine their suitability as novel thickening agent for enhanced (EOR) applications. Hereby, SB-PAMs were compared with conventional linear PAM. The effect molecular architecture on rheology, and consequently was discussed. Rheological measurements identified unique properties SB-PAMs, those showed higher robustness under shear salt...
