Abstract
An overview on polyacrylonitrile (PAN)-derived carbon nanomaterials is presented. Controlled synthesis of well-defined PAN by reversible deactivation radical polymerization (RDRP) techniques is discussed as a route to tailored carbon precursors of various architectures, such as block copolymers (BCPs) and organic-inorganic hybrids. Primary examples of different approaches to templating include the use of PAN-containing BCPs self-assembled on planar surfaces or in solution to yield: (i) bulk carbon films, (ii) discrete nano-objects and (iii) mesoporous copolymer-templated nanocarbons (CTNCs). Inorganic templates or electrospinning as a viable approach to ordered mesoporous carbons or carbon nanofibers are also discussed. Special attention is devoted to nitrogen doping in PAN-derived partially graphitic carbons and to the evaluation of nitrogen-enriched nanocarbons in energy conversion and storage applications such as supercapacitors, lithium-sulfur batteries, electrocatalysts, solar cells or CO 2 sorbents.
