This book was released on 2005 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Well aligned wall carbon nanotubes (MWCNTs), carbon nanofibers (CNFs) and other type of carbon nanostructures materials have been synthesized by a fabricated floating catalyst chemical vapor deposition (FC-CVD) method. This involved the pyrolysis of benzen-ferrocene vapor mixture. The CVD parameters (Hydrogen flow rate, reaction time and reaction temperature) were studied to selectively synthesize nanotubes and nanofibers with required dimensions. Carbon nanotubes films with a diameter of 2-50 nm and nanofiber with a diameter range from 100-300 nm were synthesized in a benzene/hydrogen atmosphere. Furthermore vapor grown carbon fibers have been synthesized with different diameters and lengths. Iron clusters that were produced from the thermal decomposition of ferrocene films were used as caralyst for the synthesis of the carbon structures. The effects of different hydrogen flow rates (50-500 ml/min) on the morphology, quality and quantity of the product were investigated. Maximum yield and purity was obtained at 300 ml/min. The effect of the reaction time on the purity and yield of carbon nanotubes was studied from 1 minutes to 60 minutes. There was no effect of the reaction time on the average diameter while maximum yield of carbon nanotubes was achieved at 45 minutes. The last variables was the reaction temperature, which was varied from 500 oC to 1200 oC. By controlling the growth temperature, carbon nanotubes (CNTs), carbon nanofibers (CNFs) and vapor grown carbon fiber with different structures were produced. Increasing the temperature has a remarkable effect on the size and shape of the catalyst and this in turn affected the diameter distribution and structure of the carbon materials. The carbon nanotubes were produced from 600 oC to 850 oC with maximum yield at 850 oC, while for the production of carbon nanofibers the reaction temperature was from 900 oC to 1000 oC with a maximum yield at 1000 oC. Vapor grown carbon fibers were produced at 1050 oC to 1200 oC with maximum yield at 1050 oC. The synthesized nanotubes/nanofibers were invertigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The thermal degradation kinetics of CNTs was investigated by dynamic thermogravity, in an air atmosphere, over the temperature range 25-800 oC and at constant nominal heating rate 10 oC/min. The correcponding activation energies, frequency factors and reaction orders were determined. Homogenous distribution of MWCNTs/CNFs in natural rubber (NR) was achieved by ultraconic assisted solution-evaporating method. Addition of 1-10 wt% of CNFs and CNTs to natural rubber as nanocomposite increased the rubber mechanical properties significantly. The properties of the composites such as tensile strength, tensile modulus, and elongation at break were studied. In addition to mechanical testing, the dispersion state of the MWNTs into NR was studied by TEM in order to understand the morphology of the resulting system. The result indicate that, by increasing the amount of CNTs and CNFs into natural rubber the ductility decreased and the material become stronger and tougher but at the same time more brittle. The results showed that by adding 1 wt% of CNTs and CNFs to NR the stress level increased sharply to 0.56413 to 0.54 Mpa respectively compared to NR which was 0.2839 MPa. At 10 wt% the stress level of CNTs with NR were increased sharply 9 times and reached to 2.55 MPa while for CNFs it increased 4.66 times and reached to 1.33 MPa.

Book Synopsis Carbon Nanotubes on Carbon Fibers by : Qiuhong Zhang
Download or read book Carbon Nanotubes on Carbon Fibers written by Qiuhong Zhang and published by . This book was released on 2010 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interface between carbon fibers (CFs) and the resin matrix in traditional high performance composites is characterized by a large discontinuity in mechanical, electrical, and thermal properties which can cause inefficient energy transfer. Due to the exceptional properties of carbon nanotubes (CNTs), their growth at the surface of carbon fibers is a promising approach to controlling interfacial interactions and achieving the enhanced bulk properties. However, the reactive conditions used to grow carbon nanotubes also have the potential to introduce defects that can degrade the mechanical properties of the carbon fiber (CF) substrate. In this study, using thermal chemical vapor deposition (CVD) method, high density multi-wall carbon nanotubes have been successfully synthesized directly on PAN-based CF surface without significantly compromising tensile properties. The influence of CVD growth conditions on the single CF tensile properties and carbon nanotube (CNT) morphology was investigated. The experimental results revealed that under high temperature growth conditions, the tensile strength of CF was greatly decreased at the beginning of CNT growth process with the largest decrease observed for sized CFs. However, the tensile strength of unsized CFs with CNT was approximately the same as the initial CF at lower growth temperature. The interfacial shear strength of CNT coated CF (CNT/CF) in epoxy was studied by means of the single-fiber fragmentation test. Results of the test indicate an improvement in interfacial shear strength with the addition of a CNT coating. This improvement can most likely be attributed to an increase in the interphase yield strength as well as an improvement in interfacial adhesion due to the presence of the nanotubes. CNT/CF also offers promise as stress and strain sensors in CF reinforced composite materials. This study investigates fundamental mechanical and electrical properties of CNT/CF using nanoindentation method by designed localized transverse compression at low loads (uN to mN) and small displacements (nm to a few um). Force, strain, stiffness, and electrical resistance were monitored simultaneously during compression experiments. The results showed that CNT/CF possess a high sensing capability between force and resistance. Hysteresis in both force-displacement and resistance-displacement curves was observed with CNT/CF, but was more evident as maximum strain increased and did not depend on strain rate. Force was higher and resistance was lower during compression as compared to decompression. A model is proposed to explain hysteresis where van der Waals forces between deformed and entangled nanotubes hinder decompression of some of the compressed tubes that are in contact with each other. This study provides a new understanding of the mechanical and electrical behavior of CNT/CF that will facilitate usage as stress and strain sensors in both stand-alone and composite materials applications. A novel method for in situ observation of nano-micro scale CNT/CF mechanical behavior by SEM has been developed in this study. The results indicated that deformation of vertical aligned CNT (VACNT) forest followed a column-like bending mechanism under localized radial (axial) compression. No fracture was observed even at very high compression strain on a VACNT forest. In order to fully understand CNT forest properties, the viscous creep behavior of VACNT arrays grown on flat Si substrate has also been characterized using a nanoindentation method. Resulting creep response was observed to consist of a short transient stage and a steady state stage in which the rate of displacement was constant. The strain rate sensitivity depended on the density of the nanotube arrays, but it was independent of the ramping (compression) rate of the indenter.
