An ex-situ method to convert vertically aligned carbon nanotubes array to horizontally aligned carbon nanotubes mat

Carbon nanotubes (CNTs) have been attracted by the researchers for their extraordinary properties and wide applications in various fields. Among numerous types of CNTs, the horizontally aligned CNTs (HACNTs) has shown many advantages due to its nano-structural features and proper arrangements. HA...
