【Journal of Alloys and Compounds】Graphene oxide/Al composites with enhanced mechanical properties fabricated by simple electrostatic interaction and powder metallurgy
Graphene has attracted great attention as an ideal reinforcement in Al matrix composites. However, there are still challenges limiting the performance of the composites, such as the homogenous distribution of graphene in Al matrices. In this paper, graphene oxide/aluminum (GO/Al) composites with enhanced mechanical properties were fabricated by electrostatic interaction and subsequent powder met...

28. Mechanical and Tribological Properties of PEEK Coatings with Different Melt Indexes Prepared by Electrostatic Powder Spray Technique
method. Amorphous coatings were obtained by quenching the as-melted coatings into the ice-water medium. Semi-crystalline coatings were obtained by annealing the amorphous coatings in an oven for 30 min at 260 degrees C. The XRD results indicates that the structure of PEEK coatings transforms from amorphous to semi-crystalline via the treatment of annealing. The hardness and the behavior friction o...

[Polym. Chem.] Fe(0) powder-catalyzed one-pot reaction: concurrent living radical polymerization and click chemistry for topological polymers
Fe(0) powder-catalyzed one-pot reaction was successfully employed to design linear and star polymers in a well-controlled manner by combining ambient temperature living radical polymerization and click chemistry. The polymerization behavior possessed the characteristics of “living”/controlled radical polymerization: the first-order kinetic plots, narrow molecular weight distribution (PDI < ...

Preparation of polypropylene/carbon nanotube composite powder with a solid-state mechanochemical pulverization process
A solid-state mechanochemical pulverization process, that is, pan milling, was used to prepare a polypropylene (PP)/carbon nanotube (CNT) composite powder. The composite powder was then melt-mixed with a twin-roll masticator to obtain a PP/CNT composite. The morphology of the PP/CNT powder and the PP/CNT composite was investigated. The crystallization and mechanical properties of the latter were a...
