Graphene-based electrodes for high performance supercapacitors are developed by taking advantage of particle size control, large mass loading, and surface functionalization of reduced graphene oxide (rGO) sheets. Two controlled sizes of graphene sheets (100 nm vs. 45 μm average lateral dimensions) were prepared to study two-electrode system performance. The nano-size graphenes led to the formation...
Carbon nanotube (CNT)/polymer composites with filler loading close to percolation threshold are demonstrated as sensor materials to monitor the thermal aging of insulation components. In order to represent the real aging conditions of the monitored component, the sensor is made of the same polymer material as the one used in the monitored component and placed in close proximity to the component. During...
We developed a facile method to transfer vertically aligned carbon nanotubes (VACNT) onto a carbon fiber paper (CFP) substrate using silicone as an adhesion layer. The resulting VACNT–CFP hybrid structure displays a very low interface resistance of 0.006Ω as a result of the Van der Waals interaction at the VACNT–CFP interface. We demonstrated in this work that the VACNT–CFP can be used as a supercapacitor...
An anomalous decrease in the thermal stability of silicone was observed when carbon nanotubes (CNTs) were added as fillers. The decreased thermal stability is found to result from the residues of cobalt nanoparticles in CNTs, whereas CNTs synthesized with other metal catalysts do not show such a phenomenon. The analysis of thermal degradation products indicates that CNT fillers do not change the mechanism...
A novel assembling process of incorporating carbon nanotubes as thermal interface materials for heat dissipation has been developed by synthesizing vertically aligned carbon nanotubes on a copper substrate and chemically bonding the carbon nanotubes to a silicon surface. The assembling process and the copper/carbon nanotubes/silicon structure are compatible with current flip-chip technique. The carbon...
Metal nanoparticles were synthesized by using surface-modified carbon nanotubes (m-CNTs) and pristine CNTs (p-CNTs) as stabilizing substrates. The surfaces of the m-CNTs were modified by the addition of hydrogen peroxide during the chemical vapor deposition synthesis. X-ray photoelectron spectroscopy showed oxygen peaks, which came from C–OH and C–O–C functional groups on the m-CNT walls. Unlike the...
