Nanostructured thermoplastic polyimide films
Structured films containing multi-walled carbon nanotubes (MWCNTs) have enhanced mechanical performance in terms of strength, fracture resistance, and creep recovery of polyimide (PI) films. Preferably, the loadings of MWCNTs can be in the range of 0.1 wt % to 0.5 wt %. The strength of the new PI films dried at 60 C. increased by 55% and 72% for 0.1 wt % MWCNT and 0.5 wt % MWCNT loadings, respectively, while the fracture resistance increased by 23% for the 0.1 wt % MWCNTs and then decreases at a loading of 0.5 wt % MWCNTs. The films can be advantageously be created by managing a corresponding shift in the annealing temperature at which the maximum strength occurs as the MWCNT loadings increase.

The present invention is a laminate where a carbon nanotube-containing layer composed at least of carbon nanotube and resin is laminated above a substrate. The laminate is a laminate where a clear layer is further laminated above a laminated surface of the carbon nanotube-containing layer. The laminate has L* being equal to or less than 2.5, a* being in a range of 2 to 2, and b* being in a range of 2 to 0.3, each measured from the laminated surface. The carbon nanotube-containing layer above the substrate is formed by coating. The clear layer is transparent resin or glass. Note that L*, a* and b* indicate values in L*a*b* color system specified in JIS Z8729.
THERMOPLASTIC CARBON COMPOSITE ELECTRODES
A new solvent-based method is presented for making low-cost composite graphite electrodes containing a thermoplastic binder. The electrodes, termed thermoplastic electrodes (TPEs), are easy to fabricate and pattern, give excellent electrochemical performance, and have high conductivity (1500 S m.sup.1). The thermoplastic binder enables the electrodes to be hot embossed, molded, templated, and/or cut with a CO.sub.2 laser into a variety of intricate patterns. These electrodes show a marked improvement in peak current, peak separation, and resistance to charge transfer over traditional carbon electrodes. The impact of electrode composition, surface treatment (sanding, polishing, plasma treatment), and graphite source were found to impact fabrication, patterning, conductivity, and electrochemical performance. Under optimized conditions, electrodes generated responses similar to more expensive and difficult to fabricate graphene and highly oriented pyrolytic graphite electrodes. These TPE electrodes provide an approach for fabricating high-performance carbon electrodes with applications ranging from sensing to batteries.
