Note that such a particle resembles several biocolloids (e.g., bacteria, virus, humic acid), functionalized nanoparticles, and environmental entities, to name a few. For such a structured particle, the conventional <span>(zeta)</span>-potential concept loses its meaning, and an extensive theory is required to analyze the electrohydrodynamics of the particle considering the penetration of ionized liquid across the shell layer. Note that the dielectric permittivity of the shell layer is often lower than that of the bulk aqueous medium, which induces the ion partitioning effect. Besides, in several practical situations, the hydrodynamic slipping may occur along the slipping plane. In addition, the slipping plane may not always be located along the surface of the inner core due to grafting of a polymeric shell layer along its surface, and thus, it may be assumed to be located somewhere within the surface polymeric layer. The slipping plane separates two regions with different Brinkman parameters. The region outside the slipping plane the Brinkmann screening length takes a finite value, which allows fluid flow across this region. In the region inside the slipping plane, the Brinkman parameter may practically be equal to infinity, but electrolyte ions still can penetrate this region. Considering all the physical aspects indicated above, we have proposed a simple model to study the electrophoresis of soft particles within the flat-plate regime. Based on the weak charge limit, we adopt the Debye-Hückel linearization to simplify the governing equations, and the explicit form of electrophoretic mobility is derived. Several closed-form analytic expressions are further deduced from the general mobility expressions valid under various limiting situations. We have illustrated our findings graphically to highlight the impact of pertinent parameters on the electrophoretic mobility of such a particle. In addition, we have further provided an estimate of the parametric range in which the particle may attain a zero mobility.

In this work, we present the sea-island structure multilayered composites based on polymethylmethacrylate (PMMA) matrix and polyvinylidene fluoride (PVDF) nanoparticles, which is constructed by the solution blending with typical solubility differences method and the layer-by-layer solution casting method. The PVDF/PMMA composite incorporated with high PVDF content is placed in the middle of the sandwich-structured composite as a non-traditional intermediate polarization layer. The PVDF/PMMA composite with low PVDF loading is placed in the outer layer to improve the insulating property of the composite. The results show that the PVDF/PMMA composites with inner and outer PVDF volume content of 30% and 10%, respectively, obtained an excellent dielectric constant value (<i>ε</i><sub><i>r</i></sub> ~ 4.35), which is 45% higher than that of PMMA (<i>ε</i><sub><i>r</i></sub> ~ 3). Meanwhile, the maximum <i>U</i><sub><i>e</i></sub> (~ 4.95 J cm<sup>−3</sup>) of the PVDF/PMMA composites at an electric field of 422.48 MV m<sup>−1</sup> was obtained, which is 207% higher than that of PMMA (<i>U</i><sub><i>e</i></sub> ~ 1.61 J cm<sup>−3</sup>). The improved energy storage capability could be attributed to the introduction of highly polarizing particles, the increased number of heterogeneous interfaces, and the multilayered construction of composite. This work provides a strategy for the preparation of advanced all-organic dielectrics with a higher discharge energy density.</p></div>","PeriodicalId":520,"journal":{"name":"Colloid and Polymer Science","volume":"302 5","pages":"829 - 841"},"PeriodicalIF":2.2,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139920499","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}
