“…These SWNT thin films showed fairly high optical transmittance and good conducting properties which are similar to those of the conventional ITO-coated poly(ethylene terephthalate) (PET; 50-200 Ω resistance and~83% transmission at 550 nm) substrate [23]. However, these methods tend to exhibit some problems such as poor film surface, optoelectronic performance, high cost, and a complex process [24]. Transfer printing, one of the most-used thin film techniques, results in difficult large-area fabrication and relatively brittle SWNT thin films.…”

Indium tin oxide (ITO) transparent electrodes are troubled with high cost and poor mechanical stability. In this study, layer-by-layer (LBL)-processed thin films with single-walled carbon nanotubes (SWNTs) exhibited high transparency and electrical conductivity as a candidate for ITO replacement. The repetitive deposition of polycations and stabilized SWNTs with a negative surfactant exhibits sufficiently linear film growth and high optoelectronic performance to be used as transparent electrodes for vertically aligned (VA) liquid crystal display (LCD) cells. The LC molecules were uniformly aligned on the all of the prepared LBL electrodes. VA LCD cells with SWNT LBL electrodes exhibited voltage-transmittance (V-T) characteristics similar to those with the conventional ITO electrodes. Although the response speeds were slower than the LCD cell with the ITO electrode, as the SWNT layers increased, the display performance was closer to the LCD cells with conventional ITO electrode. This work demonstrated the good optoelectronic performance and alignment compatibility with LC molecules of the SWNT LBL assemblies, which are potential alternatives to ITO films as transparent electrodes for LCDs.

“…We are encouraged by this as at this stage the CNT synthesis process has not yet been optimized for the combination of optical transparency and electrical conductivity, nor have any post-processing treatments been Conductance against transparency for different nanotube films. Our own results (solid circles for free-standing, squares for polymer-backed) are compared against the results of Budhadipta et al [7] (upright triangles), Geng et al [6] (inverted triangles), Zhou et al [5] (diamonds), Ma et al [8] (left-pointing triangles), Kaempgen et al [15] (stars), Green and Hersam [16] (right-pointing triangles) and Yu et al [17] (empty circles).…”

This work shows a simple, single-stage, scalable method for the continuous production of high-quality carbon nanotube-polymer transparent conductive films from carbon feedstock. Besides the ease of scalability, a particular advantage of this process is that the concentration of nanotubes in the films, and thus transparency and conductivity, can be adjusted by changing simple process parameters. Therefore, films can be readily prepared for any application desired, ranging from solar cells to flat panel displays. Our best results show a surface resistivity of the order of 300 square −1 for a film with 80% transparency, which is promising at this early stage of process development.

“…Morphological analysis (in Figs. 3,4) showed that better filler dispersion and distribution with fewer amount of voids was observed in synthetic diamond system compared with graphene nanoplatelet composites. The increase in tensile strength was due to even distribution of stress from epoxy matrix to filler.…”

“…The addition of nanomaterials to polymers confers better mechanical and barrier properties to the composite and also increases electrical and thermal conductivity [3]. At present, commonly used thermally conductive fillers include carbon nanotubes (CNTs), carbon black, silicon nitride, graphite, silicon carbide, and synthetic diamond [2][3][4][5].…”

Epoxy thin film composites filled with particulate nanofillers; synthetic diamond and graphene nanoplatelets were prepared and characterized based on tensile, thermal, and electrical properties. The influences of these two types of fillers, especially in terms of their loading, sizes and shapes, were discussed. It was found that the epoxy thin film composites incorporating synthetic diamond displayed optimum properties where the addition of synthetic diamond from 0 to 2 vol.% results in higher elastic modulus, tensile strength, elongation at break, thermal conductivity and storage modulus if compared to those of graphene nanoplatelets composites. Both thin film composites showed improvement in the glass transition temperature with increasing filler loadings. Results on the electrical conductivity of both systems showed that higher conductivity is observed in graphene nanoplatelets composites if compared to synthetic diamond composites.
