The beaker experiments respectively explored the strength of flocs formed under different PAC dosages at a fixed stirring speed and different stirring speeds at a fixed dosage. It was discovered that the floc strength was the highest at a PAC dosage of 20 mg/L, reaching 11.89 nN; when the stirring speed was 80 r/min, the floc strength was the highest, attaining 13.33 nN. Furthermore, correlation analysis between the fractal dimension of flocs and their strength revealed a strong positive correlation with a correlation coefficient above 0.90 (<i>p</i> = 0.01). Finally, an integrated analysis of floc size, fractal dimension, and strength demonstrated that the turbidity removal rate is mainly determined by the floc size and floc strength, with the floc strength playing a dominant role in most cases.

For the first time, deep eutectic solvents (DES) are simultaneously used as a green medium for AuNP (DES–AuNPs) synthesis and integrated into polyvinyl alcohol (PVA)-based eutectogels and also DES, creating a stable hybrid material with improved stability and functional properties. A series of deep eutectic solvents (DESs) based on choline chloride, proline, xylitol and betaine were synthesized. The success of the DES synthesis was confirmed using the nuclear magnetic resonance method (<sup>1</sup>H NMR). The main physical and chemical properties of solvents (viscosity, thermal stability and surface tension) were studied. The impact of the chemical’s properties of the DES (viscosity, surface tension, pH) on the effectiveness of synthesis and parameters of the obtained gold nanoparticles was investigated. These DES-synthesized AuNPs were subsequently incorporated into a PVA-DES-based eutectogel, forming a hybrid nanocomposite hydrogel system. The DES-assisted synthesis yielded stable, uniformly dispersed gold nanoparticles with controlled size. Incorporation of AuNPs into the PVA eutectogel resulted in a hybrid material with enhanced mechanical strength, thermal stability and potential conductive and optical functionalities. The eutectogel matrix facilitated uniform nanoparticle distribution without requiring additional stabilizers. The size of nanoparticles, depending on the type of DES used, varies in the range from 10 to 50 nm. The results show that the formation of DES-AuNPs significantly pronounced with the moderate acidic DES and with moderate viscosity. It has been shown that DES ensures the stability of the obtained DES-AuNPs. The second part of the work was devoted to the synthesis of eutectogel based on PVA and DES-3 (betaine–xylitol) as well as the production of a composite based on it by incorporation of DES-AuNPs. The amphiphilic nature, thermal stability and high viscosity of DES provide a unique opportunity for their introduction into polymeric materials. Thus, the current study was aimed to prepare a novel PVA-based eutectogel from PVA, DES (betaine–xylitol) and with DES-AuNPs obtained with DES (betaine–xylitol). Casting method was used to prepare eutectogel composite material PVA/DES (betaine–xylitol)/DES (betaine–xylitol)-AuNPs. The eutectogel and composite eutectogel also exhibited good functional properties such as stability in various pH and absorptivity capacity.

Due to their high surface energy, amphiphilic nature, and nanoscale dimensions, ZnO nanoparticles (ZNPs) can effectively function as Pickering stabilizers. The present study undertakes the stability of surfactant-reinforced O/W emulsions with ZNP-mediation under homogenization. The experiments were performed through Taguchi design, and the results were analyzed using the VIKOR approach. The responses included residual oil and ZNP contents, oil retention rate, droplet size/charge, emulsification index, and viscosity. UV–vis spectroscopy and DLS analyses demonstrated that introducing ZNPs facilitated the stability of O/W emulsions over time. The factor effect on the VIKOR index (<i>Q</i><sub><i>j</i></sub>) values revealed that temperature exerted the greatest influence (31%) on the response variable, closely followed by ZNP content (26%). CTAB content had a moderate impact (22%), while oil content had the least effect (13%). The optimal formulation was determined by selecting the levels that resulted in the lowest <i>Q</i><sub><i>j</i></sub> values, which were CTAB concentration at 450 mg/100 ml, oil content at 10,000 mg/100 ml, ZNP concentration at 50 mg/100 ml, and a processing temperature of 60 °C. The predicted recipe was assessed through a validation run and demonstrated well-fitting of experimental results. Such findings may be employed in optimizing the food, pharmaceuticals, cosmetic, and fine chemical formulations.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":520,"journal":{"name":"Colloid and Polymer Science","volume":"303 6","pages":"1123 - 1138"},"PeriodicalIF":2.2,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100235","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}
