Colorless polyimides (CPIs) have emerged as prime candidates for this application. Nevertheless, conventional CPI systems typically suffer from an irreconcilable trade-off between optical transparency (<80 %) and thermal robustness (T<sub>d5 %</sub> < 550 °C, CTE >20 ppm/K). In this work, we designed 7 fluorinated terphenyl dianhydrides, and accordingly obtained 28 CPI derivatives. The strong electron-withdrawing nature and high bond energy of aromatic fluorine (Ar–F) and aromatic trifluoromethyl groups (Ar-CF<sub>3</sub>) enable a high level of optical transparency while retaining high thermal decomposition stability. This achievement originates from the synergistic effects of restricted dihedral angle rotation in multi-fluorinated monomers, and controlled molecular packing density through steric hindrance-induced chain conformation. We performed systematic investigations on fluorinated CPI optical characteristics by integrating time-dependent density functional theory (TD-DFT) with machine learning. By a random forest algorithm analysis, we reveal the key roles of three electron-hole interaction descriptors (Sr, H and Hct) governing the optical transparency of CPIs. Elevated Sr values coupled with reduced H and Hct metrics effectively suppress charge transfer processes, thereby enabling the CPIs with enhanced transparency. This synergistic experimental and computational approach establishes a universal framework for rational design of advanced aromatic polymer materials, particularly for emerging flexible optoelectronic applications.</div></div>","PeriodicalId":405,"journal":{"name":"Polymer","volume":"334 ","pages":"Article 128741"},"PeriodicalIF":4.1,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144502839","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}

These elements are subject to thermo-oxidative aging when exposed to high temperatures and oxygen in their applications. Merging the rubber dimensional aspects and interaction of oxygen with the polymer matrix results in complex aging effects. Knowledge about this process is crucial for performing an assertive lifetime prediction and better component selection for specific requests. This work aims to understand the mass transport during the oxidation of NBR and EPDM rubbers by employing numerical analyses for mass transport considering heat diffusion for different sample lengths. Experimental tests considered rubber lengths from 10 to 120 mm, up to 90 aging days, and aging temperatures ranging from 80 °C to 140 °C. Experimental tests determined oxygen solubility to implement the gas concentration as a boundary condition for numerical analyses, where EPDM shows oxygen solubility 74.9% greater than NBR rubber. Furthermore, negative energy solubilization indicates a decrease in oxygen solubility with temperature increasing. Simulation results showed a reduction in oxygen concentration at the inner sample, which leads to diffusion and reaction processes reaching a steady state in this region with higher concentration at the surface. NBR shows higher reaction rates, where the diffusion-limited oxidation (DLO) effect starts at 120 °C, while EPDM samples did not present this behavior. Shorter specimens showed higher reaction rates compared to the larger ones. Fourier Transform Infrared - Attenuated Total Reflectance (FITR-ATR) spectroscopy, indentation modulus, and thermogravimetric analysis (TGA) confirmed the simulation results.","PeriodicalId":405,"journal":{"name":"Polymer","volume":"2 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144488835","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}

Toward this end, diepoxide (<em>i.e.,</em> diglycidyl ether of 1,4-butanediol) was crosslinked with an aromatic amine bearing boronic acid group (<em>e.g.,</em> 3-aminobenzeneboronic acid) as the crosslinker. The crosslinking was accomplished through the following <em>in situ</em> reactions. First, the ring-opening polyaddition of epoxide with primary amino groups afforded a linear poly(hydroxyl ether amine). Second, the reaction of di(2-hydroxyethyl)amino structural units of the linear poly(hydroxyl ether amine) with boronic acid groups led to the crosslinking. To reinforce the epoxy networks, a POSS diepoxide [<em>viz.</em> 3,13-diglycidyl double decker silsesquioxane, DDSQ] was further introduced to prompt the co-crosslinking. It was demonstrated that in the epoxy vitrimers the crosslinking was accounted for: i) the inter-chain dynamic covalent bonds and ii) the inter-chains POSS-POSS aggregation. Benefiting from the exchange of dynamic covalent bonds, the epoxy networks displayed excellent reprocessing (or recycling) properties. Thanks to the generation of POSS nanodomains, the epoxy networks were significantly reinforced. It was found that the thermomechanical properties of epoxy networks can be modulated by taking control of the crosslinking densities of the epoxy networks. In the meantime, the epoxy networks showcased the excellent shape memory properties featuring the reconfigurability. Thanks to the introduction of the organosilicon component (<em>i.e.,</em> POSS), the improved surface hydrophobicity was displayed, which is pivotal to the epoxy networks against hydrolysis of boronic ester bonds.","PeriodicalId":405,"journal":{"name":"Polymer","volume":"13 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144479587","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}

This is demonstrated by a fundamental shift in the fracture mode: from inter-bead failure in pure PEBA parts to intra-bead fracture in the PEBA/EVA blends. Consequently, the optimal formulation with 5 wt% EVA achieved a low density of 0.107 g/cm<sup>3</sup> and a high rebound resilience of 73.8 %, coupled with a 15 % increase in tensile strength (to 0.63 ± 0.04 MPa) and an 84 % increase in elongation at break (to 137 ± 6.6 %).

The shortened layer time for HSS requires quick melting and solidification of powders, which is a big challenge for traditional printing powders materials, especially the viscous elastomers. Herein, a dynamic cross-linked polyurethane containing Diels-Alder bonds (PUDA) was synthesized at kilo scale and used for HSS. The incorporation of dynamic DA bonds into PU enables the dissociation of the polymer chain under IR light heating, and will lead to fast relaxation, diffusion and dis/re-entanglement, addressing the problem of incomplete sintering and weak interlayer interaction faced by conventional PU. As a result, the ultimate tensile strength (UTS) and elongation at break (EaB) of PUDA part with reasonable dimensional accuracy can reach 8.1 MPa and 249%, respectively. The UTS of PUDA by HSS decreased by 58% compared with the hot-pressed one, whereas for the normal TPU it is 77%. Besides sintering quality, the sintering rates for PUDA is enhanced by 40% because of its fast melting and solidification, which are crucial for additive manufacturing as it comes to high-volume production.

The results demonstrated that in this ultra-high molecular weight system, the reserved shish crystals exhibit greater lengths, leading to a significant reduction in the degree of chain entanglement. As the content of reserved shish crystals increased, the signal corresponding to tilted lamellae gradually diminished. Notably, in UHMWPE films with a high content of reserved shish crystals, no tilted lamellae signal was detected, and a higher proportion of shish-kebab crystals was generated by the end of the stretching process.
