Abstract In recent years, high energy density polymer capacitors have attracted a lot of scientific interest due to their potential applications in advanced power systems and electronic devices. Here, core–shell structured TiO 2 @SrTiO 3 @polydamine nanowires (TiO @PDA NWs) were synthesized via combination surface conversion reaction in-situ polymerization method, then incorporated into the poly(vinylidene fluoride) (PVDF) matrix. Our results showed that small amount NWs can simultaneously...
Polymer-based nanocomposites are excellent and promising in developing dielectric energy storage applications, one-dimensional (1D) nanofibers with large aspect ratio exhibit superiority improving dispersibility, properties performance of polymer as compared their spherical counterparts. In this work, novel heterostructural carbon-doped inorganic nanoassemblies (TiO2/C nanofibers, NFs) were designed synthesized site via easy-processing electrospinning technique. Three different carbon...
HPLC elution behavior of isotopically different block copolymers was investigated. A series three diblock hydrogenous polystyrene and deuterated (hPS-b-dPS), in which the length hPS-block is fixed at 18 kg/mol dPS-block varied from 17 to 80 kg/mol, synthesized their retention liquid chromatography critical condition (LCCC) investigated using a C18 coated silica stationary phase mixed solvent CH2Cl2 CH3CN. At this LC separation condition, hPS retained slightly longer than dPS. The LCCC...
Irradiation crosslinked triple-SMPs of PP/LDPE blends with co-continuous structures.
Dominant electroactive phases (β‐ and γ‐phase) are induced in poly(vinylidene fluoride) (PVDF) by simply melt‐blending with a small amount of quaternary phosphonium salts (QPS), required no organic treatment for regularly‐used inorganic nanofillers. Two kinds QPS similar structure selected to investigate the correlation between crystallization kinetics from melt phase formation PVDF. What is more, nearly 100% achieved. Tetraphenylphosphonium bromide (TPPB) can effectively increase rate PVDF...
Abstract In this work, the thermal stability, rheological properties and mechanical of ethylene-tetrafluoroethylene copolymer (ETFE)/poly(vinylidene fluoride) (PVDF) blends were investigated by thermogravimetric analysis, rheometer tensile test. Thermal results indicated that had better oxidation resistance than pure ETFE. Particularly, initial decomposition temperature ( T d 0 ) at maximum rate max PVDF/ETFE (10/90 wt%) 374.49°C 480°C, which 52.6°C 34°C higher The activation energy...
By in-situ transmission electron microscopy (TEM), we performed a detailed study on the electron-beam radiation damage to nanostructured silicon nitride thin-film process layers in typical semiconductor NVM device. It was found that high-dose at 200 kV led rapid degradation of layers, i.e. thin-downing nitride, inter-diffusion O and N, formation bubble-like defects segregation N neighbouring interfaces. Further analysis revealed radiation-induced modification microstructure chemical...
The polar phase of PVDF nanowires was improved significantly with the modified AAO templates using a solution wetting method.
Flexible ferroelectric polymers are key candidates for flexible capacitive electronic devices. However, there is a lack of functional and accessible methods to control the response polymers. Herein, novel effective approach adopted tune polymers, over conventional (graft or block copolymerization). Specifically, central poly(vinylidene fluoride‐co‐trifluoroethylene) (P(VDF‐TrFE)) layer sandwiched between shielding layers (polymethacrylate (PMMA)). The differently distributed electric fields...

In order to improve the operation efficiency of picking trucks in warehouse, mathematical model routing optimization problem is established. Then PSO (Particle Swarm Optimization) and ACO (Ant Colony are used solve model. Experimental results show that both them have good overall search ability astringency. The improved a great extent by using swarm intelligent algorithms.
Abstract Inorganic montmorillonite (MMT)/poly(vinylidene fluoride) nanocomposites were prepared by two methods: co-precipitation and solution casting. The effect of preparation methods thermal treatment on crystalline phase was investigated Fourier transform infrared spectroscopy differential scanning calorimetry tests. isothermal crystallization process observed with polarized optical microscopy. It found that the solution-casting method more effective than in inducing polar melt-isothermal...
Polyvinylidene fluoride (PVDF) preferentially crosslinks upon exposure to ionizing electron beam irradiation, leading substantial changes in its physicomechanical and thermophysical properties. However, low dose irradiation produces inefficient crosslinking pure PVDF while high tends induce the concomitant process of transverse bond degradation. This has been addressed by incorporating a sensitizer into increase efficiency under irradiation. conventional sensitizers typically suffer from...
ABSTRACT In this work, we fabricated a triple‐shape memory polymeric composite (TSMPc) by electron beam irradiation of ε‐polycaprolactone (ε‐PCL)/poly(butylene adipate‐ co ‐terephthalate) (PBAT)/bentonite(50/50/4) (wt %). The 95 ± 5 kGy was confirmed to be the saturated dose both high‐temperature storage modulus and equilibrated relaxation at nonlinear elastic region. Further results demonstrated that sample exposed 41.4 exhibited excellent effect (TSME) though there existed slight plastic...
