Unveiling the existence and role of a liquid phase in a high temperature (1400 °C) pyrolytic carbon deposition process

Based on experiments aiming at depositing pyrolytic carbon onto nanotubes by means of a chemical vapor deposition (CVD) process 1400 °C, the work we report here demonstrates that involves transient formation liquid phase (here organic), and wetting physics is still able to apply in spite high temperature nanoscale, i.e., far beyond condition range usually investigated. This was unexpected, because makes all physical processes involved transitory, including fact turns itself into solid ongoing carbonization process. The observations provide an estimate time scales processes, as they have be short enough complete conditions. From practical point view, resulting material solid, all-graphenic carbon, using CVD can way dramatically modify surface energetics nano/microscale morphology nanofilaments. statement assumed also other systems.
