Scanning electron microscope image of carbon nanotube (CNT)-modified carbon fibre paper (CFP), showing a dense entanglement of CNTs uniformly covering the individual carbon fibres while retaining the microporous nature of the host CFP. From a paper by Jun Chen et al (Energy Environ. Sci., 2009, 2, 393) which discusses the use of these materials as electrodes in lithium ion battery applications.
