Multifunctional nanocomposites reinforced with carbon nanopapers

In this chapter, two fabrication methods of CNPs with chemical vapor deposition (CVD) and solution-based deposition are reviewed. The former describes the CNT forest by the catalyst silicon wafer and floating catalyst by tube furnace. The paper prepared via CVD is a good candidate for device areas because of its uniformity, thinness.

The surfactant-assisted CNTs generally require sonication to improve dispersibility. In the high-shear environment for the ultrasonicated solution, gaps and spaces should be formed between the tubes. The adsorbed surfactant is diffused into this space along the bundle length to separate the CNT bundles. The activation time without surfactant is very slow whereas the process proceeds relatively fast under the surfactant effect. On the one hand, sonication can enhance the dispersibility of CNTs in a solvent. On the

21 h of sonication. The bundle diameter initially decreases sharply from 5 to 3 nm in the first 5 min of sonication, and it then remains constant between 2 and 3 nm.
