The organization of nanoscale building blocks into a desired architecture is currently a challenging subject in the field of materials science. It is critical to direct the macroscopic-scale as well as molecular-scale arrangements of nanoscale building blocks to produce various functional materials. Self-assembly is an alternative approach to organizing nanomaterials into a functional architecture. We present a versatile self-assembly process for highly entangled carbon nanotube (CNT) scaffolds. Macroporous polymer/CNT nanocomposites were prepared by self-organized aqueous droplets. 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 a high electrical conductivity and field emitting property, which could be potentially useful for various applications in nanotechnology. |
