Flexible QPAF-4/Ta–TiO2 composite membranes are obtained using solution-casting and die coating methods. Cross-sectional scanning electron microscopy reveals that the die coating method produces a more homogenous and uniform distribution of Ta–TiO2 particles in the composite membranes than the solution-casting method. The Ta-TiO2 particles promotes the suppression of water absorbability and dimensional swelling of the composite membranes which is more pronounced in the die coated membranes. The Ta–TiO2 increase hydroxide ion conductivity to 116.9 mS cm−1 at 80 °C for the die-coated membrane, surpassing that of the pristine QPAF-4 membrane (92 mS cm−1). Ta–TiO2 with the composite membranes survive in 4 m KOH at 80 °C for 1000 h, maintaining 96–112 mS cm−1 (88–99% remaining) of initial conductivity. All composite membranes exhibit higher mechanical robustness (elongation of >200%), with the die-coated composite membranes.

The metal-free process expands the possibilities for the synthesis and application of PVDF-based block copolymers, as it allows the use of monomers that is previously incompatible with classical ATRP due to their interaction with metal catalysts. The synthesized block copolymers are characterized structurally and thermally as powder materials and in thin films. Fourier-transform infrared spectroscopy (FT-IR) analysis revealed that the crystalline phase of PVDF changes when thin films are formed. Specifically, the disappearance of the FT-IR peaks related to the gamma phase and the presence of characteristic peaks related to the alpha and beta phases indicate that film formation rearranged the PVDF chains, leading to changes in their crystalline phases.

Utilizing molecular dynamics simulations, the folding behavior of polyurethane chains is investigated of varying lengths (11, 20, and 50 monomers) in both vacuum and aqueous environments. The simulations reveal that the heterogeneous chains systematically refold to approach the designed target structures better than non-designed chains or chains with artificially disrupted hydrogen-bond networks. The subsequent synthesis of an optimized 11-mer sequence (P1) is achieved through solid-phase chemistry, with thorough characterization via NMR, MS, and SEC confirming the accuracy of the predicted sequence and its controlled chain length. Solubility tests showed favorable results across multiple solvents, highlighting the versatility of the designed polymer. This research underscores the potential of sequence-defined polyurethanes to emulate the structural and functional attributes of biological macromolecules, opening new pathways for their application in catalysis, drug delivery, and advanced material design.

This study fabricates organic–inorganic composite functional coatings using a simple one-pot method, producing materials with excellent photoresponsive, water resistance, and thermal insulation. Unmodified phosphotungstic acid serves as the inorganic photochromic filler, while methacrylate derivatives act as the polymer matrix, resulting in coatings with high initial transparency (over 85%). After 5 min of UV exposure, the samples shift to nearly non-transmittable states in the visible range and maintain color depth through 14 coloring-erasing cycles. Unlike polyvinylpyrrolidone substrates, which absorb moisture and soften quickly, this coating has a static water contact angle of up to 91.7°, showing excellent water resistance. Additionally, the composite material provides effective heat insulation in simulated chamber experiments, lowering the temperature by 15 °C compared to untreated chambers. In summary, this composite coating, with its excellent thermal insulation, rapid light responsiveness, stable cycling performance, and outstanding waterproof capabilities, proves highly suitable for applications such as smart windows, information storage, and building energy efficiency.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"225 24","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142868636","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}

However, using the hydrophilicity/hydrophobicity of polyether chains to tune their moisture resistance has been overlooked currently. In this work, two types of polyether-based diglycidyl ethers with hydrophilic poly(oxyethylene) (DGEPOE) and relatively hydrophobic poly(oxybutylene) segments (DGEPOB) are synthesized and then binary-cured with commercial diglycidyl ether of bisphenol A (DGEBA), respectively, yielding the corresponding DGEPOE:DGEBA-m:ns and DGEPOB:DGEBA-m:ns based on various ratios. For comparison, pure DGEPOEr, DGEPOBr, and DGEBAr resins are also prepared. Results show that the equilibrium water uptake of DGEPOB:DGEBA-m:ns is at least less than one-fifth of that of DGEPOE:DGEBA-m:ns; meanwhile, the diffusion coefficients of water molecules in DGEPOB:DGEBA-m:ns are also 1–2 orders of magnitude lower than those in DGEPOE:DGEBA-m:ns, demonstrating that the incorporation of hydrophobic POB chains can significantly reduce the hygroscopicity of resins. Moreover, DGEPOB:DGEBA-m:ns not only exhibit superior flexibility and ductility relative to pure DGEBAr, but display exceptional strength and toughness in comparison with pure DGEPOBr. These findings suggest that tuning the hydrophilicity/hydrophobicity of building units of epoxy monomers offers a promising strategy for developing high-performance epoxy materials, especially suitable for humid environments.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 2","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143115195","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}

For the latter, biomaterials should mimick the biological and mechanical properties of native blood vessels. To fabricate tubular constructs, the DLP-printing process is optimized by exploiting acrylate-endcapped urethane-based (AUP) polymers as the presence of the acrylate end groups render them suitable for DLP printing and desirable mechanical properties arise from the urethane segments. Four AUP variants are synthesized, exploring polyethylene glycol (PEG) and polypropylene glycol (PPG) backbones with varying acrylate functionalities (di-acrylate versus hexa-acrylate), namely UPEG2, UPEG6, UPPG2, and UPPG6. Tubular constructs with precise dimensions and morphology are fabricated. PPG-based AUP polymers exhibit superior computer-aided design/manufacturing (CAD/CAM) mimicry compared to PEG-based derivatives. Construct characterization reveals tunable mechanical properties, with elastic moduli ranging from 45 to 259 kPa, reaching values of the human blood vessels. In particular, UPPG6 shows a two-fold higher elastic modulus compared to UPPG2. All materials show excellent biocompatibility. Additionally, surface modification with gelatin-methacryloyl (GELMA) significantly enhances the cytocompatibility of UPPG2 scaffolds.

The mechanism of 1-octene isomerization is studied by combining gas chromatography-mass spectrometry (GC-MS) and density functional theory (DFT) calculations. Modified methylaluminoxanes (MMAO-3A), triethylaluminum (TEA), or triisobutylaluminum (TIBA) could significantly promote 1-octene to undergo double-bond isomerization reactions and the degree of isomerization of 1-octene increased with increasing concentrations of aluminum compounds. In addition, inhibitors such as isooctanol or isooctylamine, can disrupt the structure of the reactive aluminum species and may retard the double bond isomerization reaction of 1-octene. Therefore, reducing the concentration of aluminum compounds in the ethylene/1-octene high-temperature solution copolymerization system and the timely and sufficient use of an inhibitor at the end of the reaction are both effective in eliminating the 1-octene double bond isomerization.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"225 23","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142868176","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}

Improving molecular flexibility has been found to promote crystallization during thermal imidization and, consequently, the formation of liquid-crystal-like polyimide (LCPI) films. The optimal LCPI film exhibits an ultralow Df value of 0.00178 at 10 GHz owing to the limited intermolecular friction. Furthermore, this LCPI film absorbs significantly less water (0.59%), which endows it with favorable durability of low Df value in a humid environment. The Df value of the LCPI film at 10 GHz is only 0.00288 after 24 h of exposure to 60% relative humidity. In addition, the LCPI film exhibits a glass transition temperature, coefficient of thermal expansion, and tensile strength of 371 °C, 21.8 ppm K−1, and 240 MPa respectively, and is therefore a suitable low-dielectric-material candidate.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143114195","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}
