However, both conventional and dynamically crosslinked LCE systems fundamentally rely on chemically crosslinked networks, which has long been regarded as a prerequisite for their reversible actuation. While thermoplastic elastomers based on block copolymers offer a structural model for constructing robust physically crosslinked networks, it remains a significant challenge to transplant this design strategy into LCEs to realize reversible actuation in non-co-valently crosslinked system. Herein, we develop a physically crosslinked thermoplastic LCE system based on ABA-type triblock copolymers (PS-<i>b</i>-MCLCP-<i>b</i>-PS). Polystyrene (PS) hard-block aggregates act as reversible physical crosslinking sites, effectively replacing permanent covalent bonds. We systematically investigated the regulatory effect of the PS block content on the microstructure, mechanical properties, and thermally responsive actuation of the materials. By achieving an optimal balance between physical network confinement and the segment mobility of the liquid crystal phase, the resultant elastomer exhibits excellent reversible thermally driven actuation, well-balanced mechanical properties and solvent recyclability with high mechanical retention. Furthermore, the material demonstrates prominent wide-temperature-range damping performance attributed to the synergistic energy dissipation of the physical network and mesogen rotation. This work offers a feasible molecular design strategy for sustainable and multifunctional LCEs to break the dependence on chemical crosslinking for reversible actuation.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":517,"journal":{"name":"Chinese Journal of Polymer Science","volume":"44 10","pages":"3331 - 3339"},"PeriodicalIF":4.6,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149099198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although grafting polyelectrolyte (PE) brushes onto electrodes is a promising strategy to enhance charge storage, the role of dielectric contrast and its coupling with PE microstructure remains to be studied. In this work, a classical density functional theory (cDFT) is employed to elucidate the synergistic effects of dielectric contrast and PE microstructure on supercapacitor performance. The theory explicitly accounts for image-charge interaction induced by dielectric discontinuity, chain correlation of the PE, excluded volume effect, and electrostatic correlation. The results reveal that increasing the grafting density and chain length of the PE brushes significantly enhances the capacitance by providing more immobile charge sites and expanding the effective double-layer region, which facilitates stronger counterion adsorption. It is found that the dielectric contrast between the electrode substrate and solvent, which is often oversimplified in idealized models, plays a decisive role. A higher dielectric permittivity of the substrate weakens the shielding effect of the polarization field within the electrode. Consequently, the external electric field provides a stronger influence on the electrolyte, promoting a denser accumulation of counterions at the interface. Crucially, a high-dielectric substrate mitigates the repulsive image-charge interaction, effectively transforming it into an attractive force that further adsorbs charge near the electrode. This effect becomes particularly pronounced at high surface potentials. These results provide fundamental insights into the optimization of high-performance SCs using PE coatings.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":517,"journal":{"name":"Chinese Journal of Polymer Science","volume":"44 9","pages":"3189 - 3202"},"PeriodicalIF":4.6,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148909694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most existing physical encryption materials rely on single and predictable stimulus-response mechanisms, resulting in limited security, programmability, and service life. Herein, a high-security sequential 4D encryption system is developed based on a dynamic covalent polyurethane network that integrates shape memory, self-healing, and photochromism in one system. Arylboronic acid was incorporated into the polyurethane framework to form a dynamic boron carbamate network. The resulting boroxine crosslinks act as reversible junctions, enabling thermally triggered shape memory behavior, while simultaneously providing efficient self-healing through reversible hydrolysis and reformation. The optimized polyurethane exhibited a tensile strength of about 35 MPa, a shape-fixity ratio of >99%, and a shape-recovery ratio of up to 83% while achieving a self-healing efficiency of about 81% after thermal treatment. In parallel, the incorporation of a photochromic dye enables precise time-dependent color evolution under ultraviolet irradiation. The synergistic coupling of thermal and photonic responses allows sequential and time-gated information decoding, significantly increasing the encryption complexity and resistance to unauthorized access. The resulting films function as dynamic 4D encryption carriers from which correct information can be retrieved only through a predefined sequence of shape recovery and color transformation. This study provides a versatile strategy for next-generation physical encryption materials with intrinsic damage tolerance, long-term reliability, and storage potential in optical data storage and advanced anti-counterfeiting applications.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":517,"journal":{"name":"Chinese Journal of Polymer Science","volume":"44 10","pages":"3450 - 3462"},"PeriodicalIF":4.6,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149099122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
