Achieving mechanical robustness and highly efficient self-healing simultaneously at room temperature is always a formidable challenge for polymeric materials. Herein, series of novel supramolecular polyurethane elastomers (SPUEs) are developed by incorporating dynamic covalent boronic ester boron-nitrogen (B-N) coordination. The SPUEs demonstrate the highest tensile toughness (∼182.2 MJ m-3) to date room-temperature self-healable polymers, as well an excellent ultimate strength (∼10.5 MPa)...
Abstract Lightweight microcellular polyurethane (TPU)/carbon nanotubes (CNTs)/ nickel-coated CNTs (Ni@CNTs)/polymerizable ionic liquid copolymer (PIL) composite foams are prepared by non-solvent induced phase separation (NIPS). and Ni@CNTs modified PIL provide more heterogeneous nucleation sites inhibit the aggregation combination of structure. Compared with TPU/CNTs, TPU/CNTs/PIL TPU/CNTs/Ni@CNTs/PIL smaller structures have a high electromagnetic interference shielding effectiveness (EMI...
Supertough biocompatible and biodegradable polylactide materials were fabricated by applying a novel facile method involving reactive blending of (PLA) poly(ethylene glycol) diacylate (PEGDA) monomer with no addition exogenous radical initiators. Torque analysis FT-IR spectra confirm that cross-linking reaction acylate groups occurs in the melt process according to free polymerization mechanism. The results from differential scanning calorimetry, phase contrast optical microscopy...
A family of air-stable (phenylbuta-1,3-diynyl)palladium(II) complexes were designed and prepared in a facile synthetic procedure. Their structures characterized by (1)H (13)C NMR, MS, X-ray analysis. These Pd revealed to efficiently initiate the polymerization phenyl isocyanides living/controlled chain growth manner, which led formation poly(phenyl isocyanide)s with controlled molecular weights narrow weight distributions. NMR analysis indicated isolated isocyanide) was high...
Vitrimer network polymers are very special in that, above a characteristic temperature Tv, their dynamic covalent connectivity allows macroscopic flow while remaining cross-linked. The vitrimer is able to change from being typical elastomer polymer with thermoreversible bond-exchange reactions. This has aroused enthusiastic interest, especially for designing novel materials meet the increasing requirements of environmental protection, self-healing, and sustainable development. In this work,...
Branched, bromopentyl-tethered poly(arylene alkylene)s were synthesized by Friedel–Crafts polyhydroxyalkylation of 7-bromo-1,1,1-trifluoroheptan-2-one and biphenyl with the addition a small amount trifunctional monomer (0.5–2.0 mol %), 1,3,5-triphenylbenzene. The subsequent conversion bromomethyl group precursors to quaternary ammonium (QA) afford cationic ionomers, these ionomers then solution-cast into anion-conductive membranes. Compared linear, unbranched alkylene)-based AEM analogue,...
Abstract The isomerization strategy is employed to enhance the alkaline stability of poly(arylene piperidinium)s (PAP) while maintaining monomer commerciality and polymer architecture tunability. Isomeric piperidinium) ( i ‐PAP) exhibits improved alkali resistance relative conventional PAP, as evidenced by ex situ in cell durability tests. Following treatment 10 m aqueous NaOH at 80 °C for 360 h or operation 0.4 A cm −2 100 an anion exchange membrane fuel (AEMFC) prototype, decomposition...
In this contribution, we report on the facile synthesis of hybrid silica nanoparticles grafted with helical poly(phenyl isocyanide)s via both "grafting from" and to" strategies. First, triethoxysilanyl functionalized alkyne–Pd(II) initiator was anchored onto surface bare through silanization coupling reaction. Polymerization phenyl isocyanide using Pd(II)–anchored lead to formation isocyanide)s. The surface-initiated polymerization revealed proceed in a living/controlled chain-growth manner,...
With high optical absorption efficiency, near infrared (NIR) dyes have been proposed as theranostic agents for fluorescence imaging, photoacoustic imaging (PAI), and photothermal therapy (PTT). However, inherent hydrophobicity short circulation time of small molecule hinder the further biomedical application. Herein smart amphiphilic copolymer was synthesized containing IR780/camptothecin@poly(ε-caprolactone) (IR780/CPT@PCL) core, helical poly(phenyl isocyanide) (PPI) blocks shell with...
Aryl ether-free polyaromatics tethered with quaternary ammoniums (QAs) offer a promising candidate as an anion exchange membrane (AEM) for use in alkaline fuel cells. However, the traditional trade-off dilemma between ion conductivity and water swelling of AEM still remains. Herein, we report series poly(biphenyl alkylene) (PBPA) polymers multiple QAs per side chain that combine advantages high conductivity, diffusion coefficient, suppressed uptake. Upon increasing number on each chain,...
Vitrimer chemistry of boronic transesterification was introduced into a triblock thermoplastic elastomer to allow associative bond exchange in its highly ordered nanoscale domains. The purpose this localized dynamic cross-linking is enable reprocessing while also improving creep resistance. Triblock poly(styrene-b-butadiene-b-styrene) (SBS) used as an elastomeric vitrimer precursor gain understanding fundamental structure–property effects dynamical cross-linking. occurrence the UV-induced...
