Biomimetic nanocomposites were prepared <italic>via</italic> MTM intercalated with dopamine-conjugated CMC, leading to materials super wet strength and high flame retardancy.
Abstract Herein, a new type of healable thermoplastic poly(urethane‐urea) (PUU) elastomer with unique dual dynamic network structure consisting multi‐strength hydrogen bonds and aromatic disulfide bonds, is designed synthesized. The resultant PUU exhibits high tensile strength (41 MPa), great toughness (104 MJ m −3 ), excellent self‐healing capability (completely severes, heals at 60 ℃ for just 1 h, recovers more than 80% the original strength). Although possesses high‐density it completely...
We report a self-repairing polyurethane material with targeted repair effects on large-scale damage width of over 1 mm, which can be used to solve the problems component failure caused by conventional coatings.
Abstract In this study, a series of shape‐memory polyurethanes were prepared from polycarbonate diol (PCDL) with molecular weight 2000, trimethylol propane, and isophorone diisocyanate (IPDI). The properties crosslinked poly(carbonate urethane) (PCU) networks various compositions investigated. chemical structures thermal determined Fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry, thermogravimetric analysis. FTIR analysis indicated that PCU had the IPDI PCDL...
In this study, a novel approach has been developed to introduce orientation bundle-like β spherulite in iPP samples. The addition of UHMWPE phase, which plays the role maintaining chains, into β-nucleation agent nucleated samples leads formation oriented inner region injection molded Accordingly, both tensile strength and impact sample have improved. It proves that arrangement crystallites is another important factor determine toughness β-crystal content, especially when content relatively...
Multi-phased, ultra-tough, and self-healing elastomers containing rigid double-locked hydrophobic nanodomains reinforced by iron–catechol complexes exhibit fast stimuli-responsive shape changing.
Self-healing efficiency and mechanical strength are always a pair of contradictions polymer. Herein, series novel mussel-inspired modified graphene oxide/polyurethane composites were successfully fabricated via rational molecular design introducing hyperbranched polymer-modified oxide. The exhibit outstanding self-healing performances with 87.9%. Especially, their properties possess exceptional water-insensitivity, which presents high 92.5% under 60 °C water for 2 h 74.6% 25 6 h....
The first report of the synthesis novel self-healing elastomers possessing a dynamic dual cross-linked network and exhibiting unique two-photon fluorescence, which show potential for application in bioimaging.
In the exploration of extreme environments such as polar and outer space, elastomers used in flexible structures on equipment/facilities tend to harden brittle, losing deformability even break. This will cause huge maintenance costs serious safety risks. To solve this problem, we designed a rapidly, cryogenically self-repairing supramolecular zinc-poly(urea–urethane) elastomer with excellent mechanical properties. The exhibits flexibility bends over 90° easily after period time liquid...
Abstract To study the interaction between β‐nucleation agent and nano‐CaCO 3 in iPP matrix, dynamic rheology properties, crystallization melting behaviors, impact fracture surface of (β‐NA) nucleated filled were investigated details this study. Under suitable conditions, β‐NA has a “promoting dispersion effect” on PP matrix. However, 0.2 wt % sample worse than 0.05 at relatively high content (7.5 %). The reason is that aggregates agglomerations. α crystals induced from β‐crystals grow more...
The pressure vibration injection molding (PVIM) method was used to prepare β-nucleated isotactic polypropylene samples (PVIM β-iPP samples); a relatively low, periodical shear imposed on the polymer melt in mold at filling and packing stages. crystal structures orientation of PVIM were investigated by polarizing light microscopy (PLM), scanning electron (SEM), synchrotron two-dimensional wide-angle X-ray diffraction (2D-WAXD). PLM observations indicated that cylindrite layer, rather than...
