Highly entangled carbon nanotube scaffolds by self-organized aqueous droplets

Abstract

We present a facile and versatile directed assembly process for highly entangled carbon nanotube (CNT) scaffolds. Macroporous polymer/CNT nanocomposites were prepared by a 'breath figure' method. After pyrolysis of the nanocomposites, highly stable CNT scaffolds with diverse morphologies such as monolayered or multilayered cellular films or individual CNT rings were prepared. The cellular CNT scaffolds demonstrated high electrical conductivity and field-emission properties, which is potentially useful for various applications in electronics and energy storage devices.
