Carbon Nanotube Composite

This study measures the thermal conductivity of the MWNT/epoxy bulk composite material to enhance the heat transfer rates of the high power LED device. In this study, three different weight percentages (0.0 wt%, 0.3 wt% and 0.5 wt%) of MWNT/Epoxy composite and five different heat generating rates were employed for the investigation. The case of pure epoxy resins (0.0 wt%) was used as a reference. The responding time and the thermal conductivity of the composites were evaluated. The results show that the response is the fastest for composite with 0.5 wt% MWNT among three composites studied herein. The responses of the 0.3%wt and 0.5%wt composite are increased by 14.3%∼26.7% relative to that of the pure epoxy. Compare with that of the pure epoxy, the thermal conductivities for the cases with 0.3 wt% and 0.5 wt% MWNT/epoxy composite are increased by 15.9%∼44.9%. Further, the thermal conductivity does not vary with temperature for the temperature range studied herein. In the present study, the thermal conductivity of the composite material is found to increase mildly with the increasing heat generation rate.

Brush Plating

A film of Ni-P-Carbon-nanotube composite material is deposited on the surface of the metal substances by electro-brush plating. In this process, the composition of the Ni-P-Carbon-nanotube composite plating solution, the pretreatment on the carbon-nanotube and the effects on quality by the different brush plating technology conditions are investigated. The results shows that carbon-nanotube particles can be distributed uniformly in the coating by oxidizing, sensitizing and activating while the temperature of the plating solution should be controlled at 55°C, and PH value, 1.5~2.5. After the carbon-nanotube is added, the coating defects, such as the crack, the desquamation and the low bond strength, can be prevent effectively.

Carbon Nanotube Composite

This paper reports development of a production method to produce a composite material that is biocompatible, with high mechanical strength and resilience. The chemical precipitation conditions necessary for the production of synthetic hydroxyapatite (HAp) were determined and include pH, temperature and rate of reaction. A gas phase purification method was optimised to remove the soot impurity from the nanotubes, with transmission electron microscopy showing the preservation of the carbon nanotubes. Subsequent development of chemical and physical reinforcement techniques to produce a HAp + carbon nanotube composite material have been trialled. Hot isostatically pressed samples showed excellent densification and strength.
