Due to the high melting point of p-xylene (around 13 °C), p-xylene-based sPS gels are unexpectedly robust in allowing the formation of aerogels by direct p-xylene removal through sublimation, leading to a more efficient synthesis and better quality of aerogels with much stronger mechanical properties. Furthermore, without the interference of solvent exchange, it is more suitable to explore the influence of key parameters (sPS content and molecular weight in precursor gels) on the preparation of sPS aerogels. The content and molecular weight of sPS will affect the crystallinity and porosity of the sPS aerogels, which can further control the microstructure, mechanical properties, dielectric constant, and adsorption performance of the materials. The obtained low density sPS aerogels with 98.9% porosity exhibited a minimum dielectric constant of 1.02 at low frequencies and high adsorption capacity towards different organic solvents and common oil.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" 17","pages":" 3331-3339"},"PeriodicalIF":2.9,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143778593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This can be circumvented by using naturally occurring, highly water-soluble, and nontoxic counterions such as amino acids. In this study, we synthesized novel quaternary-ammonium-salt-based cationic gemini surfactants with glycinate as the counterion [2Cn(2-O-2) Gly, where n is the alkyl chain length, n = 10, 12, 14]. Their adsorption and aggregation properties were investigated by measuring their electrical conductivity, surface tension, and small-angle neutron scattering and compared with those of the corresponding gemini surfactants with a bromide counterion [2Cn(2-O-2) Br]. The relationship between the surface tension and concentration of 2Cn(2-O-2) Gly exhibited a unique behavior with a pronounced minimum near the critical micelle concentration. This suggests that 2Cn(2-O-2) Gly adsorbs densely at the air/water interface through hydrogen bonding between the amino nitrogen of the counterion and hydrogen atoms of water, as well as between the carboxylate oxygen of the counterion and hydrogen atoms of either the amino group or water. In an aqueous solution, 2Cn(2-O-2) Gly formed small micelles, whose structure transitioned from spherical to ellipsoidal as the concentration increased.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" 18","pages":" 3647-3655"},"PeriodicalIF":2.9,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143918862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A possible solution to this stiffness–toughness conflict has arisen through a class of material known as hybrid double-network hydrogels, which combine two polymeric networks with diametrically opposed chain stiffness and with both covalent and physical crosslinking. The vast parameter space inherent to such a system means it is difficult to identify the precise compositional parameters that lead to both high toughness and low stiffness. In this work, we address this challenge through a design of experiments (DoE) framework used to establish the statistical relationship between factors and mechanical properties of a hybrid double-network hydrogel. The crosslinking density of the networks is noted to play a prominent role in determining the stiffness of the hydrogel, while the network characteristics of the ductile network determine the toughness of the hydrogel. We also report that contrary to observations in current literature, it is possible to toughen the hydrogel without stiffening it. Therefore, the present experimentation and optimization exercise provides a hands-on guide for the use of DoE to determine the conditions for optimised mechanical properties of thin hybrid double-network hydrogels for various applications.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" 18","pages":" 3604-3612"},"PeriodicalIF":2.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/sm/d4sm01470g?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143918835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the various solid-state polymer materials for Li-ion batteries, poly(ethylene oxide) (PEO)-based solid-state electrolytes have garnered significant attention owing to their excellent interfacial affinity and high solubility for different lithium salts. However, PEO-based solid electrolytes continue to face obstacles, such as diminished ionic conductivity at ambient temperature, inadequate mechanical characteristics, and severe concentration polarization in practical applications. Researchers have proposed a series of modification strategies to enhance the room temperature ionic conductivity by exploring polymer copolymerization, blending, and hyperbranched methods. To optimize the mechanical properties, studies mainly focus on adding high-strength fillers, introducing cross-linking networks, and developing self-repairing materials. To mitigate the concentration polarization effect, a polyanionic configuration is introduced into the polymer backbone, accompanied by the addition of fillers having anionic receptor groups. In this review, the physicochemical properties and Li+ migration mechanisms of PEO-based solid polymer electrolytes are systematically described, focusing on the aforementioned modification strategies and their research progress. Additionally, it offers insights into future development trends.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" 18","pages":" 3410-3424"},"PeriodicalIF":2.9,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143918857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies highlight the advantages of transmucosal drug delivery compared to traditional delivery methods. However, external particles in mucus struggle to penetrate its deeper layers and are often eliminated by mucus clearance mechanisms, hindering effective drug delivery. To gain a deeper understanding of how material surfaces interact with mucus, we grafted brushes of poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC) onto silica surfaces, followed by the straightforward installation of a terminal boronic acid moiety (3-phenylboronic acid, APBA). The modification process was carried out following a surface-initiated activator regenerated by electron transfer atom transfer radical polymerization (SI-ARGET ATRP), a method known for its effectiveness in producing well-defined grafted polymers. After conjugation of APBA, we studied the effects of surface chemistry on properties such as pH-sensitivity and mucin adsorption. The surfaces modified with the zwitterionic polymer showed no mucin interaction regardless of system pH. However, all the surfaces containing the boronic acid showed boronic acid–sialic acid interactions, particularly at lower pH values. The insights gained from this study will enhance our understanding of the interactions between the zwitterionic PMPC and the boronic acid APBA with mucins, laying the groundwork for future chemical modifications of particle surfaces aimed at modulating their transport through mucus.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" 16","pages":" 3125-3136"},"PeriodicalIF":2.9,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The local area is determined via the well-known Voronoi tessellation technique. Our findings reveal that local areas per particle are highly dispersed, exhibiting slow dynamics over time. Additionally, the evolution of the ensemble-averaged area distribution as a function of concentration shows a long tail at large and small areas for low and high concentrations, respectively, leading to a maximum in information entropy when the distribution becomes symmetric. We introduce and analyze several expressions for local area-weighted diffusion coefficients. Notably, we find that the contribution of the averaged diffusion coefficient can be expressed in terms of local areas, establishing a new framework to determine the weighted influence of each local area on particle dynamics.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" 18","pages":" 3492-3502"},"PeriodicalIF":2.9,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143802016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the case of smaller polydispersity, stable clusters tend to form owing to stable face-to-face contact. In this case, however, larger magnetic particle–particle interaction strengths are necessary. Since the applied magnetic field enables the magnetic moment of each particle to incline in the field direction, it enhances the formation of chain-like clusters. In the case of larger polydispersity, compared to the smaller polydispersity cases, particle aggregates are formed even in the region of smaller magnetic particle–particle interactions. In this case, small particles combine with a growing cluster composed of large particles to form larger clusters. However, these small particles tend to disturb the internal structure of the particle aggregates, leading to chain-like clusters with narrower widths than those in the case of smaller polydispersity. These characteristics of the particle aggregates confirm that the broadness of polydispersity in a magnetic cubic particle suspension is applicable for controlling the internal structure and regime transition in the internal structure of particle aggregates. This may be an important feature in the development of surface modification techniques using magnetic cubic particle suspensions.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" 17","pages":" 3254-3266"},"PeriodicalIF":2.9,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/sm/d4sm01516a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
