Incorporating liposomes into hydrogels presents a promising approach to enhancing stability and sustaining drug delivery. However, optimizing their administration, responsiveness, and synergistic interaction with the tissue penetration process to improve drug permeation efficiency and bioavailability remains a critical challenge. To address these limitations, this study introduces an intelligent, injectable hydrogel delivery system based on the crosslinking of thiolated hyaluronic acid with a versatile hyperbranched PEG macromer (HPM). The high reactivity and acid-responsive properties of HPM enable in situ, rapid liposome encapsulation, significantly enhancing liposome stability while ensuring excellent injectability and localized therapeutic effects. As a proof of concept, this hydrogel system is applied as a skin dressing, facilitating controlled liposome release while improving stratum corneum hydration, thereby markedly enhancing the transdermal delivery of the antioxidant coenzyme Q10 (CoQ10). Compared to the direct application of free CoQ10 dispersions, this system achieves an impressive 16.6-fold increase in bioavailability, highlighting its strong potential for applications in transdermal drug delivery and localized disease treatment.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500310"},"PeriodicalIF":4.2,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143955520","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}

Unfortunately, such metal-free electrode materials suffer from low practical capacities and poor rate capabilities, due to low intrinsic conductivity, limited redox-active sites, and insufficient electrochemical utilization. Herein, integrating conductive carbon nanotubes (CNTs) with bipolar-type COFs enriched by multi-electron redox-active sites is rationally crafted by in situ Schiff base condensation to fabricate robust core-shell hierarchical heterostructures (CNT@COF). Remarkably, the as-fabricated CNT@COF cathode delivers a large reversible capacity (253.1 mAh g-1 at 0.2 A g-1), high rate capability (161.6 mA h g-1 at 5 A g-1), and excellent cycling stability (retaining 76.6% of initial capacity at 5 A g-1 over 1000 cycles), because of the fast ion/electron transport and high utilization of active groups. Accordingly, both spectroscopy techniques and theoretical calculations are employed to reveal the redox reaction mechanisms of COF moieties and the reversible conversion of bipolar-type nitrogen-containing active centers (imine, triazine, and triphenylamine) against with PF6 -/Li+ is rationalized clearly. This work crafts an unusual strategy to address common issues for organic polymer electrodes by macromolecular engineering to unlock the barrier of high-capacity and high-rate storage in powerful batteries.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500133"},"PeriodicalIF":4.2,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143964670","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}

Herein, a reversible volume reduction is explored in ultrathin spherical hydrogel shells made of poly(methacrylic acid) in response to osmotic pressure changes in solution. The 4-µm pH-responsive hydrogel shells are synthesized via polymer multilayer assembly on sacrificial spherical microparticles to produce nanostructured hydrogel shells with varied thicknesses. The degree of hydrogel shell volume reduction and rapid recovery of its spherical shape in response to osmotically induced deformation and after stress removal are studied in highly hydrated shells. The spherical hydrogel shape uniformly deforms inward by producing a dimple at critical osmotic pressures (1-15 kN m-2), followed by the formation of a soft half-shell. These deformations are entirely uniform and are rapidly reversed upon stress removal. These large shape deformations and quick recovery are due to the shell's low elasticity of 4.0 ± 0.1 MPa, characteristic of elastomers. This study demonstrates the potential of the ultrathin highly hydrated hydrogel microshells for extending the class of elastomeric colloids with programmable compressibility and flow properties, leading to new fundamental and applied knowledge about elastic non-spherical hydrogels.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500257"},"PeriodicalIF":4.2,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143959732","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 TLCs were then incorporated into diglycidyl ether bisphenol A (DGEBA) resin at 60 °C to formulate OCERs and assess their effectiveness. Optical microscopy of the OCERs showed uniform dispersion of the TLCs. Cure kinetics, evaluated by dynamic and isothermal DSC and rheological analysis, revealed that the stability of urea bonds of the TLCs was affected by phenyl group substitution and the amino group type. Urea bonds formed from dichlorophenyl isocyanate (DCPI) with secondary amino groups showed the lowest thermal stability. The TLC-5 synthesized from DCPI and triethylenetetramine (TETA), was most effective, initiating the curing of DGEBA at 120 °C. OCER-5, prepared with TLC-5 and DGEBA and cured at 140 °C, was analyzed by DMA, showing a Tg of 135 °C.

The two lower Mn copolymers dewet the silicon substrates after annealing, whereas the two higher Mn copolymers reveal the formation of holes and islands by optical microscopy, suggesting their microphase separation into lamellae structures orientated parallel to the substrate. The ordering of these weakly segregated diblock copolymers is verified by X-ray reflectivity (XRR) and grazing-incidence small-angle X-ray scattering (GISAXS). XRR provided the film thickness and lamellae spacing by probing along the direction perpendicular to the sample surface, whereas GISAXS probes the nanoscale morphology along the sample plane and the lateral and vertical correlation lengths of the films by analyzing the diffuse scattering. The lamellae thicknesses determined by XRR and GISAXS are in good agreement with those measured by atomic force microscopy.

In this work, the polypropylene-b-polybutene block copolymers are designed and synthesized with the sequential polymerization method. The in situ wide-angle X-ray diffraction characterization demonstrates that polybutene (PB) and polypropylene (PP) sequences are both crystallizable, which crystallize into the mixture of tetragonal and trigonal phases, and monoclinic phase, respectively. In the meanwhile, The PP sequences in block copolymers exhibit the self-nucleation effect similar to the homopolymer, of which the PP crystallization kinetics is accelerated with decreasing self-nucleation temperatures (Ts). Unexpectedly, this self-nucleation effect of PP blocks on PB crystallization exhibits a rather complex and non-monotonous dependence on Ts. It is interesting to see that as Ts is lowered to Domains II and III to largely accelerate crystallization of PP, PB crystallization is suppressed. However, as the further decreased Ts only anneals PP crystallites, the suppressed PB crystallization could recover. This complex self-nucleation on crystallization is interpreted by the constraint of evolved PP crystallites on PB sequences.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500194"},"PeriodicalIF":4.2,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143959151","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}
