碩士 === 元智大學 === 機械工程學系 === 97 === Carbon nanotubes have been widely used in a variety of nano-technology industry.The main reason is its light weight, high strength, high toughness, can be deflection, high surface area, high thermal conductivity, good electrical conductivity, and chemical stability etc. When the ratio of different content of CNTs evenly distributed in the composite material, in addition to enhanced mechanical properties of composite materials (mechanical property) and secondly to reduce the friction coefficient (friction coefficient) and upgrading of anti-wear.Because of the size of carbon nanotubes is minuteness, there is lack of general discussion about the research into carbon nanotubes in composite materials in the distribution of directional (direction) and alignment problems.That’s cause the traditional making process of composite materials can’t use carbon nanotubes with a uniform (uniform alignment) placed in the matrix. Therefore this research will be referred to electrophoresis (DEP) technology to manipulate carbon nanotubes to uniform distribution and alignment directionally.On this base, to get the alignment from the alignment of carbon nanotubes through the calculated by the SEM observation, and then through the relation schema to acquire the effect of electrode gap to carbon nanotubes’s alignment. Finally according to this result to produce the carbon nanotubes composite material. This research mainly to explore the electrical properties of ultimate multi-walled carbon nanotubes in composite,material, mechanical properties and thermal mechanical properties.
