Graphite Composites

Activated nitrogen-enriched carbon/reduced expanded graphite composites (ANC/REG-c) with different composite ratio were prepared by in-situ polymerization, carbonization, activation and reduction of aniline and expanded graphite. These were characterized by XPS, SEM and electrochemical measurements. XPS shows that N atoms exist in the ANC and ANC/REG-c. Compared to mechanical mixture of ANC and REG(ANC/REG-m), ANC/REG-c shows lower resistance and higherCp1(185.4 F/g) vs 124.3 F/g of ANC/REG-m measured by CV due to the introduction of the composite sturcture. When the composite ratio of ANC/REG-c is 6:1, the ANC/REG-c shows the highestCp1(264.0 F/g) and its symmetric supercapacitor also shows the best synthetical electrochemical performances. The optimal supercapacitor presents good cycle stability. ANC/REG-c is a suitable electrode material for supercapacitors.

Abstract Bulk copper, copper-graphene and copper-graphite composites were produced from copper-thermally expanded graphite (TEG) powder mixtures with 0-3 wt.% TEG contents via modified powder metallurgy process that includes powder milling in a planetary mill at 350 rpm for 5 hours, compaction, and vacuum annealing at 1030 °C for 1 hour. Phase composition and microstructure of the composites were analysed by XRD and SEM techniques. According to Raman spectroscopy, TEG transforms into a few layer graphene flakes in case of composites with 0.1-1 wt.% of carbon additive, while for 3 wt.% of carbon additive it remains in the form of graphite. The addition of 0.1 wt.% TEG results in the tensile strength increase up to 160 MPa (from 93 MPa for pure copper specimen synthesized via the similar synthesis route). Vickers hardness obtained for Specimens under the study is independent fromthe composite composition.
