碩士 === 元智大學 === 機械工程學系 === 98 === Composite materials in order of our modern inventions affect the lives of those around, composite materials, or through two kinds of material through a variety of different products formed by processing this type of product because of the required degree of different Therefore, characteristics also differ, basically speaking with the future order mass light, high intensity and other characteristics, and in this study to Jia CNTs connected to the carbon fiber surface as a reinforcement to enhance a variety of Merit performance, and in the selection of the main causes of CNTs is based on their own with high intensity and large specific surface area, nanoscale porosity and type of carbon fiber also has features like Merit, if these two kinds of new profiles are Data integration can be conducted by adding carbon nanotubes of the case after it has increased the effectiveness, in addition to carbon fibers and carbon nanotubes with pore of the material, these features can also be used as absorption materials are also volatile organic gases and storage of hydrogen can also be developed into the application, through the so Good performance in this study were two kinds of this material as combined Bingqie discussion in a variety of physical characteristics and ambient temperature adsorption of organic vapors under the circumstances, and assess In the multiple-feasibility. In this study, use of chemical vapor deposition (CVD) synthesis of CNT / ACF samples used catalyst to iron, cobalt, nickel, carbon nanotubes as synthetic precursors, the catalyst using different combination of the future observation Synthesis of CNTs of difference, for the synthesis of conducting characteristics of the sample after the analysis and Toluene adsorption of organic gases, this observation in different concentrations and the temperature under the CNT / Toluene adsorption performance of activated carbon fibers, and establish sorption isotherm and the adsorption mechanisms may be estimated. Preliminary results showed that carbon nanotubes in the FESEM observation dual-catalyst growth of the case to the best effect and, since the behavior synthesized CNTs by HRTEM observation of morphology on and not much variance exists, but iv the degree of graphitization of the samples also can be found from the Raman ratio of graphite samples with high degree of carbon fiber surface by means of CNTs with more, but the findings from the TGA behavior of samples synthesized antioxidant level is not good. Nitrogen adsorption / desorption curves can be learned from the behavior of the synthesized sample adsorption to porous, you can use the gas adsorption on Toluene and further estimate the CNT / ACF samples, adsorption ability and reproducibility. By adsorption results can be found in the adsorption of ACF physical adsorption followed the pattern, using a variety of different isothermal adsorption equation Fitting amount of saturated adsorption was found to Freundlich adsorption results are more close to the results of this study, when added In order to CNT formation of nanocomposite materials for adsorption and not much help on sex, excessive addition to the impact of catalyst, the adsorbent and adsorbate interaction will also affect the adsorption heat of the results ACF adsorption of VOCs by gas adsorption will increase with the decrease in contrast, after heat treatment through the order of their adsorption pattern was changed, which means that the sample after heat treatment through the order will change its adsorption mode
