This contrast further amplifies reservoir heterogeneity and makes it increasingly difficult for chemical flooding to enhance oil recovery (EOR) through balanced displacement. Here, we constructed an in situ emulsification system composed of an associating polymer, surfactant, and salt (APSS) for coupled profile control and oil displacement. The crude-oil emulsification behavior, microstructure and rheology of high-water-content emulsions, seepage characteristics in a 70% water-cut sand-packed plate model, and EOR performance in water-flooded parallel heterogeneous sand-pack models were systematically evaluated. A polyacrylamide/surfactant/salt system (PSS) with comparable apparent viscosity and oil–water interfacial tension was used as the control. The results show that APSS exhibits a distinctive water-cut-responsive emulsification behavior that requires the synergistic action of all three components. In the high-water-content range of 50–90%, APSS forms highly viscous emulsions, whereas under low-water-content conditions it either forms low-viscosity emulsions or does not emulsify. The viscosity of the stable, high-viscosity APSS emulsions is 5 ~ 20 times higher than that of the injected displacing fluid and the crude oil. By contrast, PSS forms only weakly stable emulsions over a narrower water-content range of 40 ~ 60%, with viscosities only 2 ~ 3 times higher than those of the displacing fluid or crude oil. Confocal laser scanning microscopy (CLSM) and rheological measurements of the APSS emulsion at 70% water content reveal the coexistence of spherical oil-in-water droplets and filamentous/strand-like aggregates, giving rise to a multilevel structure and gel-like rheological behavior. In three heterogeneous displacement models with permeability contrasts of 5 ~ 10, APSS not only emulsified and displaced oil efficiently in high-permeability zones while generating substantial flow resistance, but also redirected the displacing fluid toward low-permeability zones. The average total oil recoveries achieved by APSS were 92.2%, 46.2%, and 89.8%, which were markedly higher than the corresponding values for PSS (79.8%, 32.8%, and 32.7%). This water-cut-viscosity-responsive in situ emulsification system provides a new technical strategy and experimental basis for deep fluid diversion and enhanced oil recovery in high-water-cut heterogeneous reservoirs.</p></div>","PeriodicalId":520,"journal":{"name":"Colloid and Polymer Science","volume":"304 10","pages":"2779 - 2799"},"PeriodicalIF":2.9,"publicationDate":"2026-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148962054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional formulation strategies primarily employ co-solvents or strong alkaline agents such as sodium hydroxide. Therefore, ibuprofen-loaded solid lipid nanoparticles (SLNs) were developed using an inorganic salt-mediated in situ ionization approach to improve drug incorporation and topical application. SLNs were prepared using the hot-melt homogenization method with beeswax as the lipid matrix. Different inorganic salts (K₂CO₃, Na₂CO₃, and Na₃PO₄) were employed to induce in situ ionization during nanoparticle formation. The obtained SLNs were incorporated into hydrogel systems containing Carbopol or xanthan gum. The interactions between SLNs and hydrogels were evaluated with respect to physicochemical characteristics, rheological properties, and <i>ex vivo</i> skin permeation. Formulations prepared without alkaline agents or at drug-to-alkaline molar ratios exhibited phase separation and poor stability. In contrast, in situ ionization at a 1:1 molar ratio produced homogeneous SLNs with uniform nanoparticles (200 nm), zeta potential values around − 20 mV, and encapsulation efficiency of up to 70.25%. FTIR and DSC analyses confirmed the conversion of crystalline ibuprofen into a less crystalline or amorphous salt form within the lipid matrix. Na₃PO₄ produced SLNs with higher surface charge and improved physical stability, whereas K₂CO₃ and Na₂CO₃ generated smaller and more homogeneous nanoparticles.

Initially, porous carbon material (PC) was synthesized using a carbonization-activation method, serving as a carrier for Fe<sub>3</sub>O<sub>4</sub> particles. This process led to the successful creation of the Fe<sub>3</sub>O<sub>4</sub>/PC composite. Subsequently, this composite was used as a modifier to produce waterborne polyurethane (PC-FWPU) through in-situ polymerization. The structure and properties of the Fe<sub>3</sub>O<sub>4</sub>/PC composites were systematically examined, focusing on how varying the amount of Fe<sub>3</sub>O<sub>4</sub>/PC affected the stability of the PC-FWPU composite emulsion and the properties of the resulting film. The study’s results revealed that the porous carbon synthesized here boasts a high specific surface area of 1387.90 m²/g and a hierarchical pore structure, offering ample spatial sites and structural support for the uniform loading of Fe<sub>3</sub>O<sub>4</sub> nanoparticles. Measurements of water contact angle, thermogravimetric analysis (TGA), and mechanical properties showed that incorporating Fe<sub>3</sub>O<sub>4</sub>/PC composites significantly enhanced the water resistance, thermal stability, and mechanical performance of the PC-FWPU films. At an optimal Fe<sub>3</sub>O<sub>4</sub>/PC loading of 4.0 wt%, the PC-FWPU composite film exhibited a water contact angle of 134.6°, demonstrating excellent hydrophobicity. The temperature at which 50% weight loss occurs (T<sub>50%</sub>) increased markedly from 298.1℃ for pure waterborne polyurethane (WPU) to 388.7℃, reflecting a 30.4% enhancement. Concurrently, the tensile strength rose from 17.32 MPa to 30.97 MPa, a significant increase of 78.8%. Additionally, the introduction of Fe<sub>3</sub>O<sub>4</sub>/PC imparted certain magnetic and electrical conductive properties to the WPU matrix.

The composite fibers exhibit excellent anti-static properties. Meanwhile, the PANI/wool composite fibers have good washing and abrasion resistance. The electric resistance of the PANI/wool composite fibers is 24.3 MΩ/cm after 200 times of washing and is 14.5 MΩ/cm after 600 times of rubbing, at least 6 orders of magnitude lower than that of the ordinary wool fibers (1.60 × 10<sup>7</sup> MΩ/cm).

It is worth noting that the fabrics woven from this kind of anti-static fibers are sensitive to the pH. The color changes of the clothing can be used to judge the acidity of the environment.

Gram-positive and gram-negative bacteria were both tested for antibacterial effectiveness. Antioxidant activities were assessed by a free radical scavenging assay. GS-Au NPs at 8x dilution had an 88% DPPH decreasing capacity, while CS-Au NPs at 8x dilution had 73%. The CS-AuNPs and GS-AuNPs displayed a target-oriented effect on MCF7 at lower IC<sub>50</sub> concentrations of 100% concentrated and 2-fold diluted compared to the L929 (IC<sub>50</sub> value is much more above of 100% concentration for both types of AuNPs). Overall, in comparison to CS-AuNPs, the phytosynthesized GS-AuNPs exhibit broad activities that allow for their usage in a variety of biological and biotechnological applications.</p></div>","PeriodicalId":520,"journal":{"name":"Colloid and Polymer Science","volume":"304 9","pages":"2453 - 2471"},"PeriodicalIF":2.9,"publicationDate":"2026-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148807459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
