Synthesis of PMMA-b-PS Block Copolymer by Emulsion ATRP and its Self-Assembly Property
The well-defined block copolymer PMMA-b-PS was prepared by two-step ATRP in emulsion system. GPC results indicate that Mn increased linearly with conversion and polydispersity remained relatively narrow. It presents the characteristics of living polymerization in emulsion system. FT-IR demonstrated that block copolyme…
Effects of the Mould Pressure and Mould Pressing Time on the Properties of Graphite/Phenolic Resin Composites
Polymer matrix composites made from phenolic resin are filled with natural graphite powders. They are fabricated by compression molding technique.

Harmonic Loss Calculation of Three-Phase Transformer Based on J-A Model
Beginning with characterizing the nonlinearities of transformer, this paper uses the J-A model to represent the hysteresis of iron core, and fits the model in calculating exciting current. Compared with the other methods, such as polynomial and describing function method, J-A model is more capable in representing nonl…
Deposition of Functional Membranes by Through-Substrate Plane-Plate Dielectric-Barrier Discharge
A novel roll-to-roll deposition method, namely, "through-substrate plane-plate dielectric-barrier discharge," was developed. This method uses a dielectric-barrier-discharge plasma plate, which has antenna and ground lines in a dielectric material, as an electrode. A film substrate was placed on the electrode so that a…
