In the mobile sink based sensor networks, the energy consumption issue becomes the key point because of energy constraint on sensor nodes. We established a maximizing minimum probability of energy consumption model, and gave a strong mathematical proof. We also proposed a maximizing minimum probability of energy consumption (MMPEC) data collection algorithm based on this model. MMPEC optimize the length of path distributed between child nodes and the aggregation nodes, and achieves low energy consumption of the whole network. The simulation results show that MMPEC is far superior to other hierarchical data collection methods based on a mobile sink in energy consumption. © 2015, Chinese Institute of Electronics.

A method for producing a thermoplastic resin composition includes melt-blending 50 to 80 parts by mass of a crystalline polyester resin and 20 to 50 parts by mass of an amorphous polyester resin with an extruder, thereby producing a first polyester resin compound. The method further includes melt-blending 90 to 99 parts by mass of the crystalline polyester resin and 1 to 10 parts by mass of a styrene-acrylonitrile-glycidyl methacrylate terpolymer with the extruder or a different extruder, thereby producing a second polyester resin compound. The method further includes compounding 1 to 10 parts by mass of the first polyester resin compound, 1 to 10 parts by mass of the second polyester resin compound, and respective predetermined amounts of a polycarbonate resin, a flame retardant, an antidrip agent, an antioxidant, a lubricant and a toughening agent.

The influence of ionic liquids on the structure and tensile properties of ionic liquids (ILs)/polyamide 6 (PA6) specimens with different ratios was investigated by X-ray diffraction (XRD), differential scanning calorimetry (DSC), fourier transform infrared spectroscopy (FTIR) and mechanical properties tests. The results revealed that the partial α crystalline form was transformed to γ crystalline form for ILs/PA6 specimens. The melting temperature decreased with the increase of ILs content. The peak wavenumbers of N-H stretching vibration and C=O stretching vibration of PA6 molecules reduced, while the peak wavenumbers ascribed to the mixed motions of C-N stretching and N-H in-plane bending vibration increased. Compared with pure PA6 specimens, the elongation at break for ILs/PA6 specimens with different ratios was improved in different degrees. © 2016 Elsevier B.V.

Microencapsulized red phosphorus and phosphorus flame retardants named RC200 were employed to prepare fire retardant high-performance ABS composites which were toughened by different impact modifiers via twin-screw extrusion. An addition of 10phr ethylene-methyl acrylate copolymer(EMA) elastomer was proved to toughen flame retardant ABS composite efficiently. And furthermore, the flame retardant ABS composite exhibited excellent physical properties including favorable melt fluidity, better impact strength of 78 J/m and V-0 class for UL94 rating testing. Compared to thermoplastic polyurethane(TPU) containing soft component (polyether), TPU comprised hard ingredient (polyester) indicated more significant flame retardancy. Combustion and limiting oxygen index(LOI) testing reveal that nano-montmorillonite(MMT) shows a remarkable synergistic effects on flame-retardance enhancement of ABS. Thermogravimetric analysis demonstrates that adding MMT leads to greatly improved thermal stability and much larger residual quantity.

The effect of the blending sequence and the viscosity ratio on the phase morphology and mechanical properties of blends of polypropylene and polyphenylene ether was investigated in present study. It is found that that the Izod impact strength of PPE/PP alloy compounded via two step extrusion method can be improved significantly. A preblending SEBS with PPE can make the compatibilizer SEBS move easily to the PPE/PP interface and the blends had finer dispersion and better properties. Also, the experimental results have showed a clear dependence of the blend phase morphology and properties on the viscosity ratio. The Izod impact strength of PPE/PP blend can be improved by decreaseing the viscosity ratio ηPPE/ηPP. In addition, the screw configuration containing an elongational flow field has proved to be more effective in deforming particles than a shear flow field, leading to finer dispersion and better properties.

The aim of this work was to learn the solvent effect on preparation of poly(butylenes-carbonate)(PBC) electrospinning nanofiber filmes. For this purpose, the dissolvability and electro-spinnability of PBC in seventeen pure solvents and two blend solvents, together with morphology of the result PBC nanofiber films were investigated in detail. Results revealed that the solvent dielectric constant had a strong influence on the split process, and that affected the morphology of as-spun PBC nanofibers. Compared with poly(ε-caprolactone) (PCL) nanofibers, PBC nanofiber films appeared better hydrophilic performance, and enhanced mechanical property which can be attributed to its low crystallization speed. © 2014 The Authors.

The present invention relates to an easily-plated PC/ABS alloy and its preparation method. The PC/ABS alloy includes following components: 30-70 parts by weight (pbw) of PC resin, 15-65 pbw of ABS resin, 5-10 pbw of PEO resin, 0.1-1 pbw of antioxidant, and 0.1-1 pbw of lubricant. For preparation, blending the PC resin, ABS resin, PEO resin, antioxidant and lubricant in a mixer; and putting a mixture in a twin-screw extruder for granulation, thus producing easily-plated PC/ABS alloy. The method is simple and practicable. PEO resin makes PC/ABS surface have the property of hydrophilicity, which makes the etching solution easier to wet the surface when under etching, so that the etching becomes much easier. The binding force of hydrophilic group on the surface of PEO to the metal is strong. The binding force of PC/ABS alloy material is improved due to the combination between the chemical bond and physical force.
