Effect of electric field variation in alignment of SWNT/PC nanocomposites
INTRODUCTION Since the discovery of carbon nanotubes (CNTs) in 1991 by Iijima 1, they have been considered as ideal fillers in nanocomposites material. The interest in this area stems from the fact that polymer offer many desirable qualities, such as toughness, space savings, low weight, good surface finish flexibility and low cost2-3. The exceptional and unique properties of CNTs offer a great advantage for the production of improved composites, but CNTs, however, have rarely been used as electrical or mechanical inclusions in a polymer matrix because of the difficulty in achieving efficient dispersion. This difficulty is due to vander Waals attraction among tubes, in combination with their high surface area and high aspect ratio, often leads to significant agglomeration, thus preventing efficient transfer of their superior properties to the matrix 4. To overcome this limitation, assemblies of aligned nanotubes have been proposed to reach the individual properties of SWNTs in a bulk material. Herein we report a simple procedure for the alignment of SWNTs under relatively high DC electric field.
