Carbon Nanotube/Mica Composite Powder Prepared by Substrate-induced Method
Source abstract
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 2.0×10~4Ω·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.
