Abstract

Carbon nanotube (CNT)/Mica conductice composite powder was prepared by a substrate-induced method. The mica was modified by poly (vinyl alcohol) (PVA) or polyacrylamide (PAM), and mixed with CNT suspension, then CNT adsorbed on mica surface. The resistivity (ρ) of composite powder was measured. XPS, SEM were used to characterize the obtained CNT/Mica. The results show that the resistivity is 2.0×104 Ω·cm when the unmodified mica is used to prepare 1.0wt% CNT/Mica, while the resistivity can reach 86.6Ω·cm when modified mica is used. Modified mica can improve CNT adsorption and dispersion, and decrease the resistivity of CNT/Mica remarkably.

Key words： carbon nanotube; composite powder; dispersion; PVA
