From: Conductivity enhancement of multiwalled carbon nanotube thin film via thermal compression method
TEM images of the as-sprayed and thermally compressed CNTs. The high-resolution images of (a) the as-sprayed CNTs and (b) the CNTs after the thermal compression with the compression force of 100 N at 200°C for 50 min. (c) The magnified image of the squared region in (b) and (d) the CNTF after the thermal compression with the compression force of 100 N at 400°C for 50 min.
