Abstract
UV irradiation or oxygen plasma exposure of multi-walled carbon nanotubes (MWCNT) was performed as pretreatment of liquid phase deposition (LPD) of TiO2 or SiO2. ATR/FT-IR analysis of the pretreated MWCNT suggests that the UV irradiated surface was oxidized whereas the surface was not oxidized through oxygen plasma exposure. It was found that complete coating was achieved by the sufficient plasma exposure, as a result of FE-SEM observation of MWCNTs on which TiO2 or SiO2 is deposited by LPD method after the pretreatment. Aluminum alloy composites are fabrecated using the MWCNTs coated with SiO2 by LPD after the plasma exposure as compound filler.
