In this work, toughening of epoxy resin was studied using recycled polyethylene terephthalate (rPET) as toughening agent and multi-carboxyl polyethylene glycol (PEGc) synthesized from polyethylene glycol and trimellitic anhydride as a modifier. Mechanical property tests indicated that the addition of 6 phr of rPET increased the impact strength of the epoxy resin from 6.77 ± 2.26 kJ/m² to 19.10 ± 3.53 kJ/m². Moreover, the further addition of PEGc could produce a significant toughening effect with rPET. Specifically, the impact strength, tensile strength, and elastic modulus of the epoxy resin containing 6 phr of rPET and 15 phr of PEGc increased by 318.8 %, 13.9 %, and 23.9 %, respectively, compared with those of pure EP. The significant toughening effect is attributed to the skeleton provided by rPET and flexible molecular chains provided by PEGc. Meanwhile, the results of molecular dynamics simulation confirmed that PEGc can effectively enhance the modulus of rPET/EP composites. Through the curing kinetic parameters obtained from non-isothermal DSC tests, the Kamal autocatalytic model was found to better describe the curing reaction process of the epoxy composites. This work provides a low-cost route for fabricating epoxy composites with excellent toughness.</div></div>","PeriodicalId":20916,"journal":{"name":"Reactive & Functional Polymers","volume":"207 ","pages":"Article 106142"},"PeriodicalIF":4.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143144829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the current BPIs have shortcomings of reduced thermal and electrical capabilities, low dimension stability, and poor masking ability. Hence, the development of BPIs with outstanding overall properties is urgent. To obtain high-performance BPIs, this study introduces a chromophore called 3,6-bis(thiophen-2-yl)diketopyrrolopyrroles (TDPP), which is known for its exceptional molar extinction coefficient. A new diamine (DPPTPyDA) incorporating TDPP grafted with pyrimidine groups was synthesized. DPPTPyDA was then polymerized with pyromellitic dianhydride (PMDA) to yield black polyimide (DPPTPyPI). TDPP grafted with pyrimidine acted as a chromophore system that red-shifted and broadened the light absorption of PI. The resulting DPPTPyPI exhibited total absorption in the visible region and showed a deep black appearance. Its cut-off wavelength (λ_cut) reached 695 nm, and CIE-Lab coordinate <em>L*</em> was low to 1.25. DPPTPyPI also displayed a low coefficient of thermal expansion (CTE) and outstanding thermal and electrical characteristics. Density functional theory calculations demonstrated that the exceptional light absorption of DPPTPyPI primarily stemmed from the transitions from HOMO to LUMO+1 within the chromophore framework. The flexible copper-clad laminate (FCCL) fabricated from DPPTPyPI showed exceptional peeling strength and resistance to high soldering temperature. This intrinsic BPI with excellent overall properties has important applications in the field of microelectronics.</div></div>","PeriodicalId":20916,"journal":{"name":"Reactive & Functional Polymers","volume":"207 ","pages":"Article 106140"},"PeriodicalIF":4.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143144828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To investigate the impact of VGCF on the energy and combustion performance of the aluminum (Al)/polyvinylidene fluoride (PVDF) metastable intermolecular composite (MIC) system, the composite films of Al/PVDF with varying VGCF contents were prepared using the spin-coating method. The micromorphology, crystal structure, mechanical property, energy, and combustion performance of the films were analyzed. The results demonstrate that the addition of VGCF greatly enhanced the system's performance, particularly in terms of hydrophobicity and tensile properties. Furthermore, the participation of VGCF also promoted gas generation during the combustion process, leading to an increase and subsequent decrease in reaction heat release and burning rate within a specific range. The optimal range for VGCF addition in composite films was determined to be 0.8 %–1.2 %. When the addition amount is 0.8 %, the heat release of total reaction, heat release of fluorination reaction, and burning rate reached maximum values of 4773 J·g⁻¹, 4551 J·g⁻¹, and 77.2 mm·s⁻¹, respectively.

Although the incorporation of flame-retardant additives into the liquid electrolyte can enhance the safety of LMBs, it often compromises electrochemical performance. To achieve a balance, a flame-retardant separator with thermally responsive properties has been developed by coating a core-shell flame-retardant polymer (poly(methyl methacrylate) (PMMA) as the shell and tris (pentafluorophenyl) phosphine (TPFPP) as the core) onto a polyethylene (PE) separator using an aqueous technique. Compared to the original PE separator, the TPFPP@PMMA flame-retardant separator exhibits superior mechanical strength and electrolyte wettability, along with significantly improved flame retardancy and thermal stability. Due to the excellent compatibility of PMMA polymer with lithium anode, a stable cycle life of over 500 hours for the Li||Li symmetrical coin cell has been achieved. The capacity retention of the Li||LiNi_0.8Co_0.1Mn_0.1O₂ battery is higher than that of the PE separator (80.0% vs. 65.8%) after 100 cycles between 3.0 V and 4.35 V, ascribed to the formation of a stable and robust cathode electrolyte interface (CEI) film, primarily composed of rich LiF and poor Li₂CO₃ on the cathode surface, induced by the PT/PE separator.
