Functional carbon nanotubes for high-quality charge transfer and moisture regulation through membranes: structural and functional insights.

Functional single walled carbon nanotubes (SWCNTs) are assembled onto porous supports by using layer-by-layer (LBL) approaches. Directed nano-assembly of nanotubes is identified as a crucial factor for controlling the combined functions of hybrid-composite membranes, including charge and moisture transport. In both the cases, donor-acceptor interactions are indicated to be responsible for the rearrangement of nanotubes inside the LBL multilayer and their related properties.
