The epoxy (EP) resin is being intensively applied in electronics packaging, the 5th generation communication technology (5G) and composite tanks for pressurized hydrogen fuel storage. For these applications, to date it has remained a grand challenge for EP to achieve a demanding property portfolio, e.g., the combination of satisfactory fire retardancy, high thermal conductivity (λ) and excellent mechanical properties. Herein, we report an iron phenylphosphinate-functionalized graphene oxide ( [email protected] ) nanohybrid by a facile yet scalable in-situ self-assembly method. Compared to the virgin EP, the EP nanocomposite with 2.0 wt% of [email protected] shows 42.5 % improvement in the limiting oxygen index (LOI), 46.2 % and 23.5 % reductions in the peak heat release rate (PHRR) and total heat release rate (THR), respectively, and a desired UL-94 V-0 rating. In addition, the resultant EP nanocomposite also exhibits improved tensile strength and λ (increased by 32.6 % and 96.0 %, respectively) relative to virgin EP. Such desirable integrated performances outperform those of the previously-reported EP counterparts, because of the multiple synergistic effects between FeHP and GO. This work provides an innovative strategy for the design of multifunctional EP nanocomposites, which holds the great promise for many industrial applications.

Composites based on poly (trimethylene terephthalate) (PTT)/acrylonitrile butadiene styrene (ABS) blend with maleic anhydride grafted PTT (PTT-g-MA) as a compatibilizer and carbon nanotubes (CNTs) as reinforcers were prepared via melt-mixing, and the mechanical, electrical, and barrier properties of the as-fabricated composites were evaluated. Scanning electron microscopy (SEM) characterization of the cross-section of the composites after tensile test showed improved phase stability in the presence of the compatibilizer PTT-g-MA. The toughness of the composites was also improved with the addition of the compatibilizer and CNTs. Electrical conductivity tests were carried out and the results showed that CNT-reinforced composite exhibited significantly increased conductivity. Since barrier properties are very sensitive to structural changes, the oxygen transmission rate (OTR) of the composites was measured and the results showed that the composites possess a much high oxygen barrier compared to that of the neat PTT or ABS. © 2019 Kingfa SCI. & TECH.

Aqueous organic contaminants, including dyes, disinfection by-products (DBPs), pharmaceuticals and personal care products (PPCPs), and other emerging contaminants, have been under research lens due to their potential ecotoxicological and adverse health impacts. Semiconductor-based photocatalysis has been considered as one of the most promising approaches to treat organic contaminants in water. Recently, conducting polymers (CPs) and their nanocomposites (CPNs) have attracted much attention due to their tunable electrochemical properties, low costs, and efficacy. The nanocomposites of conducting polymers, with metals and metal oxides, have shown excellent photocatalytic efficiencies for removing organic contaminants, including dyes and PPCPs. This paper presents a critical review of the recent advances in the photocatalysis of aqueous organic contaminants using CPs and CPNs. We have discussed different strategies to prepare CPs and CPNs, characterization of CPs, and factors affecting CP-based photocatalysis. This review also highlights the potential and the promise offered by CPs for the next generation water treatment by discussing unsolved questions, technical challenges, and future directions for CP-based photocatalysis. Although our review highlights CPs as one of the most promising photocatalytic materials to degrade trace organics, most of the CP-based photocatalysis studies to date have been conducted in a batch-scale mode and with dye as a model contaminant. There is a need for more CP-based photocatalytic research, involving real-world water matrices, UV treatment, stability and reusability of catalysts, continuous flow reactor design, cost-benefit analysis, and pilot-scale testing before CPs could find their application in the real-world treatment systems. © 2020

We report the large-scale synthesis of photoluminescent single-chain nanoparticles (SCNPs) by electrostatic-mediated intramolecular crosslinking in a concentrated solution of 40 mg mL −1 by continuous addition of the free radical initiator. Poly(vinyl benzyl chloride) was charged by quaternization with vinyl-imidazolium for the intramolecular crosslinking by using 2,2-dimethoxy-2-phenylacetophenone (DMAP) as the radical initiator. Under the electrostatic repulsion thus interchain isolation, the intrachain crosslinking experiences the transition from coil through pearl-necklace to globular state. The SCNPs demonstrate strong photoluminescence in the visible range when the non-emissive units are confined thereby. Composition and microstructure of the SCNPs are tunable. The photoluminescent tadpole-like Janus SCNP can be used to selectively illuminate interfacial membranes while stabilizing the emulsions.

Shape Permanence in Diarylethene-Functionalized Liquid-Crystal Elastomers Facilitated by Thiol-Anhydride Dynamic Chemistry

引用

Angewandte Chemie 2022年第11期134卷

作者： Tayler S. Hebner Maciej Podgórski Sudheendran Mavila Timothy J. White Christopher N. Bowman Department of Chemical and Biological Engineering University of Colorado Boulder 596 UCB Boulder CO 80309 USA Department of Polymer Chemistry Institute of Chemical Sciences Faculty of Chemistry Maria Curie-Sklowdowska University M.

Diarylethene-functionalized liquid-crystalline elastomers (DAE-LCEs) containing thiol-anhydride bonds were prepared and shown to undergo reversible, reprogrammable photoinduced actuation. Upon exposure to UV light, a monodomain DAE-LCE generated 5.5 % strain. This photogenerated strain was demonstrated to be optically reversible over five cycles of alternating UV/Visible light exposure with minimal photochrome fatigue. The incorporation of thiol-anhydride dynamic bonds allowed for retention of actuated states. Further, re-programming of the nematic director was achieved by heating above the temperature for bond exchange to occur (70 °C) yet below the nematic-to-isotropic transition temperature (100 °C) such that order was maintained between mesogens. The observed thermal stability of each of the diarylethene isomers of over 72 h allowed for decoupling of photo-induced processes and polymer network effects, showing that both polymer relaxation and back-isomerization of the diarylethene contributed to LCE relaxation over a period of 12 hours after actuation unless bond exchange occurred.
