Abstract In this paper, the pressing and sintering properties of three kinds copper-coated chromium composite powder copper-chromium mechanical mixed with same copper content were compared studied. The was prepared by a diffusion method, liquid electroless plating method an added binder. results show that increase in content, advantage copper-clad is more obvious. density, hardness, size shrink...

The paper 1 contains results of investigation of the structure and some properties of copper and molybdenum based composite materials and the processing parameters in their production via electron-beam evaporation/condensation. The present work has been done in connection with the necessity of improvement and repeatability of the properties of condensed molybdenum-copper materials, which partic...

Pentamethyldiethylenetriamine, a precursor of polyurethane, was synthesized with 75% yield by permethylation diethylenetriamine methanol over composite copper catalysts.

3D printing using thermoplastics has become very popular in recent years, however, it is challenging to provide a metal coating on 3D objects without using specialized and expensive tools. Herein, a novel acrylic paint containing malachite for coating on 3D printed objects is introduced, which can be transformed to copper via one-step laser treatment. The malachite containing pigment can be use...

Background: An electronic device consists of electronic components attached on a circuit board. Reliability of such a device is limited to fatigue properties of the components as well as of the board. Printed circuit board (PCB) consists of conducting traces and vertical interconnect access (via) out of copper embedded in a composite material. Usually the composite material is fiber reinforced ...

Processing and manipulation of highly conductive pristine graphene in large quantities are still major challenges in the practical application of graphene for electric device. In the present study, we report the liquid-phase exfoliation of graphite in toluene using well-defined poly(3-hexylthiophene) (P3HT) to produce a P3HT/graphene composite. We synthesize and use regioregular P3HT with contr...

The copper oxide (CuO) nanowires/functionalized graphene (f-graphene) composite material was successfully composed by a one-pot synthesis method. The f-graphene synthesized through the Birch reduction chemistry method was modified with functional group "-(CH₂)₅COOH", and the CuO nanowires (NWs) were well dispersed in the f-graphene sheets. When used as anode materials in lithium-ion batteries, ...
