| 講演要旨 |
The talk will review the research carried out at NASA-Johnson Space Center on the single wall carbon nanotube (SWCNT) production, purification, characterization and applications. In-situ diagnostics during nanotube production by laser oven process include spatial and temporal data of passive emission and laser induced fluorescence from C2, C3 and Nickel atoms in the plume. Details of the results from the “parametric study” of the pulsed laser ablation process indicate the effect of production parameters including temperature, buffer gas, flow rate, pressure, and laser fluence. Enhancement of production achieved by rastering the graphite target will be discussed. Details of the recently established NASA-JSC protocol for characterization of SWCNT material will be presented. Applications of SWCNTs for improving mechanical, electrical and thermal property enhancement of different materials will be discussed. |
