Abstract:

Modern day engineering systems research presently lacks techniques to exploit the unique properties of many nanomaterials; coupled with this challenge exists the need to interface these nanomaterials with microscale and macroscale platforms. A nanomaterial of particular interest is the carbon nanotube (CNT), due to its enhanced physical properties. In addition to varied electrical properties, the CNT has demonstrated high thermal conductivity and tensile strength compared to conventional fiber materials. CNTs are beginning to see commercial applications in areas in which sufficient study ha

Carbon nanotubes (CNTs) have been successfully grafted onto the surfaces of spherical silica gels via a floating-catalyst chemical vapour deposition method. Two types of silica gels were used as substrates; SG6 (6 – 8 nm pore size) and SG26 (26 – 34 nm pore size). The optimum growth conditions were found to be 760 °C growth temperature, 3 hours growth time, and 5 wt .% of ferrocene catalyst (dissolved in toluene) injected into the furnace at a rate of 0.04 ml/min. Under these conditions, CNTs coated the exterior surface of the gels with growth occurring from both the pores and from the surface

By adding the BC, mechanical properties of CNT/epoxy resin composites were increased dramatically compared to CNT composites without BC. Optical microscopy and scanning electron microscopy were conducted to study the microstructure of CNT/copolymer/epoxy resin composites.

Abstract:

Carbon nanostructures have been extensively used in different applications; ranging from electronic and optoelectronic devices to energy conversion. The interest stems from the fact that covalently bonded carbon atoms can form a wide variety of structures with zero-, one- and two-dimensional configuration with different physical properties. For instance, while fullerene molecules (zero-dimensional carbon structures) realize semiconductor behavior, two-dimensional graphene shows metallic behavior with exceptional electron mobility. Moreover the possibility to even further tune these fascinating

碩士<br>國立中正大學<br>化學工程所<br>98<br>This research was mainly including two parts:First,we used FeNi catalyst to synthesize primary CNTs which the size of diameter is larger by the 1st-CVD process. And we deposited the Ni particles both on the homemade CNTs and the commercial CNTs which the size of diameter is smaller by impregnation and calcination,then we obtained the branched CNTs by the 2nd-CVD process. Secondary, two types of the above branched CNTs was preparation to the suspension,and finally we fabricate branched carbon nanotube paper by vacuum filtration. In the experiment results of part

Abstract:

碩士<br>東海大學<br>物理學系<br>95<br>Abstract The encapsulation of foreign materials inside hollow cavities of nanotubes has been intensively studied. Confinement through the nanotube provided the opportunity to synthesize and explore vary small size encapsulates that would possibly exhibit peculiar quantum confinement effects. In this study, a method based on vapor phase transport and chemical vapor reaction was used to form radial heterostructures between GaN nanowires and carbon nanotubes(GaN@CNT NWs). Moreover, a metal catalyzed two-steps approach was used to fabricate axial heterostructures betwee

碩士<br>大葉大學<br>電機工程學系碩士在職專班<br>94<br>Nano-Sized nickel particles were deposited on silicon substrates by sol-gel process as the catalysts for the growth of carbon nanotubes using atmospheric thermal CVD process. The results show that several parameters which incluning during the synthesis has prominent effect on the diameter and morphology of the carbon nanotube.The pretreatment mode, ambient gases, its flow rate and synthesis temp. A pretreatment temperature of 800℃ ~ 900℃ is adequate for CNT growth.Ammonia is a better pretreatment gas than hydrogen in reduning the content of amorphous carbona
