Owing to this specific structure, these assemblies are at thermodynamic equilibrium, allowing for dynamic transitions between unimer and aggregated states. We hypothesize that the same copolymer can stabilize emulsions with distinct properties at varying pH, whether in its unimer or micellar state (Pickering emulsions).</div><div>Experiments: We characterized the copolymer behavior in aqueous solutions across pH range using dynamic light scattering (DLS), contact angle measurements, and dynamic tensiometry. Dodecane-in-water emulsions were prepared using the copolymer at various pH values. Emulsion characteristics were studied using optical microscopy and laser granulometry, complemented by visual observations to assess stability over time. The adsorption of polymer micelles at the emulsion droplet surface was investigated using transmission electron microscopy (TEM) of freeze-fractured samples.</div><div>Findings: Above pH 5–6, the copolymer acts as a macromolecular surfactant, resulting in emulsions with short-term stability. At lower pH (pH &lt;5–6), when the copolymer self-assembles into micelles, very stable emulsions are obtained, exhibiting long-term stability (&gt; 2 years) even at low copolymer concentrations (as low as 0.001 wt% with respect to total sample weight). Drop size is tunable with the copolymer concentration. TEM analysis of freeze-fractured emulsions reveals micelle adsorption at the droplet surface at low pH, highlighting their efficiency as Pickering emulsion stabilizers. Despite the copolymer reversible assembly in solution, no emulsion breakup occurs when pH increases to reach the unimer state domain. This unexpected behavior suggests that adsorbed copolymer micelles lose pH-sensitivity at the water-dodecane interface, demonstrating a unique system where interfacial behavior differs from solution behavior.</div></div>","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"710 ","pages":"Article 140019"},"PeriodicalIF":9.7,"publicationDate":"2026-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146137109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cocatalyst, Au-Ag hollow alloy particles (HAPs), was embedded within the hollow structure via sulfur vacancy-mediated strong interfacial coupling, which synergistically enhances light scattering/reflection and promotes directional charge transfer. Subsequently, the localized surface plasmon resonance (LSPR) of Au-Ag HAPs extends light absorption into the NIR region and generates an intensely enhanced local electromagnetic field, enabling efficient hot electron excitation and remarkable photothermal conversion.

The measured surface tension value is accurate only once these viscous effects have subsided. Therefore, the relaxation time represents the minimum surface age value achievable during the measurement process. We experimentally established the minimum surface age needed to measure the dynamic and static surface tension of a fluid with a specific viscosity using three widely used methods: the Pendant drop method, the Wilhelmy plate method, and the Bubble pressure method.
