Graphene-Metal Oxide based Nanocomposites for Supercapacitor Applications

Selvakumar D., Nagaraju P., Jayavel R., Anna University, IN

Two dimensional graphene-based nanocomposites have been synthesized through the modified Hummer’s method and chemical reduction process. Transition metal oxides were decorated on the graphene sheets by in-situ hydrothermal method. The composites were formed with graphene [...]

Electrochemically Exfoliated Graphene: Production and High Performances.

Wang J., Institute of Coal Chemistry, Chinese Academy of Sciences, CN

I’d like to present that graphene flakes have been produced with good properties and potentially used widely through electrochemical approaches. The electrochemically exfoliated graphene-based materials exhibit high performances in thermal management, electrocatalysis, supercapacitor, batteries and [...]

Graphene based core–shell additives for increasing the thermal conductivity of epoxy nanocomposites

Eksik O., Bartolucci S.F., Gupta T., Fard H., Tasciuca T.B., Koratkar N., Istanbul Technical University, TR

We studied novel technique to enhance the thermal conductivity of epoxy nanocomposites using graphene coated poly-methyl-methacrylate (PMMA) balls. PMMA balls with a diameter in the range of 200–300 nm were synthesized using suspension polymerization. These [...]

Graphene Synthesized in the Gas Phase: Research and Applications

Dato A., Harvey Mudd College, US

Pure and highly ordered graphene can be rapidly and continuously produced through the substrate-free gas-phase synthesis method. The single-step process involves sending precursors, such as ethanol and dimethyl ether, directly into atmospheric-pressure microwave-generated argon plasmas, [...]

Electric Field Assisted Placement of Carbon Nanotubes Using Sacrificial Graphene Electrodes

Engel M., Farmer D., Tirapu Azpiroz J., Seo J.-W.T., Kang J., Avouris P., Hersam M.C., Krupke R., Steiner M., IBM Research, BR

Here we detail a complete process flow to overcome the challenge of placement of carbon nanotubes on solid surfaces, limiting "bottom-up", large-scale integration in semiconductor process technology. To date most bottom up placement strategies are [...]

Strain sensing with CNT nanocomposites: static, cyclic and dynamic electromechanical material characterization.

Magnafico E., Casalotti A., Karimzadeh M., Chytanya Chinnan K., Lanzara G., University of Rome, Roma Tre, IT

Carbon Nanotube (CNT) nanocomposites are one of the most important candidates to realize innovative strain sensors for Structural Health Monitoring (SHM) applications. In this work, sensors were made of Multi-walled Carbon Nanotubes (MWNTs) embedded in [...]

Dispersion technology for CNTs with nano pre-mixer

Takatsuka T., Iida Y., THINKY corporation, JP

Carbon nanotubes (CNTs) and other strongly aggregated materials by van der Waals’ force are known for their excellent material properties with fewer amounts when they are deagglomerated and dispersed. Nano pre-mixer’s, PR-1* (THINKY, Japan), operating [...]
