In situ polymerization of six-membered cyclic 1,3-dioxane leads to a polymer electrolyte with superior oxidation stability and elevated Li-metal compatibility, which enables the stable operation batteries various state-of-the-art high-voltage cathodes.
Polyimides (PIs) are widely used in microelectronics and advanced optical industries due to their excellent overall properties. However, the efficient mild synthesis of PIs from commercially available raw materials poses great challenges polymer chemistry. Here, a rapid versatile thiol-Michael click reaction between imide-containing bismaleimides (BMI) aromatic dithiol is developed. The structural diversity BMI allows for manipulation thermal properties by molecular design with different...
ABSTRACT Shape memory poly(ε‐caprolactone) (PCL) networks with different molecular weights of PCL diol were prepared via thiol–ene reaction in this work. The highly efficient ensured a uniform distribution chains between crosslinker, contributing well‐defined network architecture good mechanical and shape properties. 1 H NMR spectra used to confirm that was completely converted into acrylate‐terminated PCL. Gel content experiment Fourier‐transform infrared showed almost all samples exhibited...
A new surface micromachining way of ultrashort plus laser for C/SiC composites with high quality and efficiency was demonstrated, including picosecond femtosecond laser. Surface morphologies, element content bonding states were analysed in detail after machined by power respectively. For machining, the amount nanoparticles increased increasing power. At 20 50 mW, Si–C, C–C Si–O bonds existed nanoparticles, while Si–C disappeared at 70 mW. cauliflower-like particles periodic ripple certain...
We demonstrate that the left-handed materials (LHMs) with unity dendritic unit cells arrayed in disorder state present still passband and negative refractive. The resonance behavior of LHMs disturbed periodic lattice, quasi-periodic lattice random array are experimentally investigated. Employing amended retrieval method, disordered exhibits a index refraction. Basing on such lens, subwavelength imaging experiment give clearly point image full wave at half maximum width 0.4 lambda 9.3 GHz....
To understand the service behaviour of SiC fibres, effects ambient environment and temperature on microstructure, mechanical property oxidation these fibres were investigated. The result shows that, surface becomes rough after exposure in air from 973 to 1573 K due formation small SiO2 particles, a smooth film will be formed fibre at 1773 K. In Ar atmosphere, change into clusters large crystals heat treatment for 2 h 2373 tensile strength decreased by 66 95% when exposed 5 min Ar,...
The present work investigates the thermal shock properties of a two-dimensional carbon fibre reinforced silicon carbide composite (2D-C/SiC) in air. 2D-C/SiC specimens were thermally shocked up to 60 cycles between 900 and 300°C. resistance was characterised by residual ultimate tensile strength (UTS) interlaminar shear (ILSS). surface morphology microstructure examined scanning electron microscope an X-ray diffractometer. It is found that ILSS more sensitive damage caused shock. retains its...
Abstract A volumetric ablation model for EPDM (ethylene- propylene-diene monomer) is established in this paper. This considers the complex physicochemical process porous structure of a char layer. An physics based on layer and another heterogeneous are then built. In model, porosity used to describe Gas diffusion chemical reactions introduced entire structure. Through detailed formation analysis, causes compact or loose vapor deposition (CVD) reaction between pyrolysis gas skeleton...
