{"title":"Adaptive Polymer Gels with Model-Network Structure","authors":"Sebastian Seiffert, Michael Lang","doi":"10.1002/macp.70286","DOIUrl":"https://doi.org/10.1002/macp.70286","url":null,"abstract":"<p>Amphiphilic polymer gels are composed of a polymer network with both hydrophilic and hydrophobic parts. This combination gives rise to dual swelling in polar and nonpolar solvents, leading to hierarchical microstructures and tunable physical properties. As a result, they feature favorable properties with delicate dependency on the environmental medium polarity, such as environmentally sensitive viscoelasticity and selective permeability. This multifaceted responsiveness makes them attractive for numerous applications, ranging from soft contact lenses and membranes to drug delivery systems, tissue engineering scaffolds, or matrices for gel or solid polymer electrolytes. They have also been investigated for applications in phase-transfer enzymatic catalysis, antifouling surfaces, or pH sensing.</p><p>To truly exploit this large potential, however, it is necessary to rationally understand the interplay between the network nano- and microstructure and the resulting gel properties. The network structure features multiple levels of complexity, ranging from local connectivity defects on the mesh scale, network inhomogeneities on larger scales, and potentially microphase-separated domains on even larger scales. These structures are partly imparted permanently during the network synthesis and partly further adaptable to the current experimental conditions.</p><p>Over the years, systematic experimental investigations along with computational simulations have been used to obtain multi-scale insights into the microstructures, heterogeneities, dynamics, and properties of amphiphilic polymer gels, predominantly in view of their elastic and swelling characteristics, their mechanics, solute transport, and biocompatibility. Despite these advances, significant challenges remain. The reproducibility and performance of amphiphilic polymer gels are strongly influenced by network homogeneities, polymer-network strand dispersities, and the arrangement and partitioning of hydrophilic and hydrophobic domains. To overcome these challenges in the attempt of unravelling rational structure–property relations, model networks with well-defined strand lengths and controlled architectures appear particularly valuable.</p><p>Among the amphiphilic polymer gels, amphiphilic polymer co-networks (APCN) are a particularly interesting subclass that allows for the study of long-standing problems for theory, whereas unique routes for synthesis or highly specific applications can be targeted at the same time. Unlike other amphiphilic systems, an APCN disintegrates upon removing the bonds between the parts of different philicity. Since the connections between the different polymers are central for these materials, one can even construct these materials starting from these connecting bonds by utilizing the physics of block co-polymers, which allows model systems with known and regular phase morphology to be designed with simultaneous control of modulus and swelling in various solvents.</","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"227 11","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/macp.70286","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148173966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of hydroxyl end groups in the thermoplastic results in two effects: an improved crosslink density and a reduced activation energy for the initial curing stage by 25 kJ·mol⁻¹. The glass transition temperature has been determined for epoxy polymers that contain polyethersulfone with both open and blocked hydroxyl end groups. Phase equilibria in the initial systems and during the curing process were investigated via optical interferometry. It has been established that the systems are characterized by amorphous stratification diagrams, with a lower critical solution temperature of 110°C or 140°C for PESU with open and with blocked end groups, respectively. Curing with 4,4'-diaminodiphenylsulfon at 180°C leads to the formation of homogeneous systems. The data obtained in this study will be useful for developers of composite binders and technologists working with high-temperature compounds that exhibit predictable properties due to their homogeneous structure in the cured state.</p>\u0000 </div>","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"227 11","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148100621","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}

Damping materials can effectively suppress vibration and reduce noise, thereby extending the service life of mechanical systems. To broaden the effective damping temperature range (Δ<i>T</i>) of polyurethane elastomers, several strategies can be employed, including introducing pendant chain structures into the polyurethane matrix, physically blending with resins that have different glass transition temperatures (<i>T</i>g), or adjusting the crosslinking density of the polyurethane elastomer. In this study, we adopted a precise molecular design approach by incorporating bisphenol A polyoxypropylene ether (BPAPO)—a compound containing bisphenol A-like structures—into the soft segments. This modification introduced rigid benzene rings into the polymer backbone, effectively restricting the internal rotation of chain segments. The resulting elastomer (PT) exhibited a significant improvement in tensile strength, increasing from 0.344 to 0.897 MPa, and the effective damping temperature range expanded from 66.2°C (for the unmodified material) to 82.2°C for the PT-1 elastomer.

As a result, the PET/HT/HZC composites exhibited homogeneous nanoparticle dispersion, which simultaneously enhanced light absorption and far-infrared (FIR) emission. PET/HT/HZC filaments prepared via the melt spinning process demonstrated tensile strength values exceeding 3.2 cN/tex. Under simulated sunlight, the fabric containing 1 wt.% HT/HZC nanoparticles (F-PET-1.0) reached 65.4°C within 150 s, which was 28.4°C higher than pristine PET fabric. Field tests in Shanghai further confirmed the warming effect, with fabric surface temperatures up to 24°C higher than unmodified PET fabrics. Moreover, the FIR emissivity of F-PET-1.0 increased to 0.900 after ten washing cycles, corresponding to a 15.2% enhancement compared with pristine PET, potentially contributing to improved thermal comfort and physiological benefits, such as enhanced blood circulation.
