ELECTRO-MECHANICALLY ROBUST, FLEXIBLE CARBON NANOTUBE-PDMS COMPOSITE FOR HIGH PERFORMANCE FIELD EMISSION

摘要

We present a method for fabricating flexible multi-wall carbon nanotubes (MWNTs)-polymer (poly-dimethylsiloxane, PDMS) composites for high performance field emission devices and other flexible electronic applications. The polymer matrix isolates individual nanotubes on its surface, reducing mutual [1] and give rise to impressive field emission properties. The MWNT-PDMS composites are extremely flexible and electro-mechanically robust since they remain electrically conducting under large strains. The above mentioned features make these MWNT-PDMS composites suitable for future applications as multifunctional flexible devices such as pressure and gas sensors as well as flexible sensors and display devices.
