چکیده
The effects of binder chemistry on electrical-conductivity development, i.e., dynamic percolation, in carbon nanotube (CNT)-filled epoxy-based pastes during curing were investigated. electrical resistivities the are influenced not only by dispersivity CNT filler but also pastes. electrical-conductivity-development kinetics accelerated introducing a reactive diluent, namely phenyl glycidyl ether, to binder. As shown alternating current impedance spectroscopy, development is governed decrease interfacial resistance between units. Electrical-conductivity does occur synchronously with shrinkage binder; thus, chemical state interface adjacent fillers key parameter for enhancing conductivity. Thus, control this an essential concept developing electrically conductive CNT-filled

Effect of nanotube alignment on percolation conductivity in carbon nanotube/polymer composites
Percolation conductivity of a stick network depends on alignment as well as concentration. We show that both dependences exhibit critical (power-law) behavior, and study the alignment threshold in detail. The highest conductivity occurs for slightly aligned, rather than isotropic, sticks. Experiments on single wall carbon nanotube composites are supported by Monte Carlo simulations. These resul...
متن کاملConductive Carbon Nanotube Composite Microprobes
Because of their outstanding electrical and mechanical properties, including high stiffness and mechanical resilience, ballistic electron transport at micrometer scales, and high current-carrying capacity, carbon nanotubes (CNTs) could enable a new class of electrical elements ranging from transistors to interconnects. However, realizing the properties of individual CNTs in assemblies of CNTs h...
متن کاملOn the lack of thermal percolation in carbon nanotube composites
Recent experiments demonstrated very low percolation thresholds for carbon nanotube composites signified by steep increases in electrical conductivity at very low nanotube loadings. By contrast, thermal transport measurements, even on the same samples, showed no signature of the percolation threshold. These contrasting behaviors are particularly intriguing considering that both transport proces...
متن کاملDynamic catalyst restructuring during carbon nanotube growth.
We study the restructuring of solid nickel catalyst nanoparticles during carbon nanotube growth by environmental transmission electron microscopy and multiscale modeling. Our molecular dynamics/continuum transport calculations of surface-diffusion-mediated restructuring are in quantitative agreement with the experimentally observed catalyst shape evolutions. The restructuring time scale is dete...
