The preparation of optically transparent and electrically conductive composite thin films composed of multi-walled carbon nanotube (MWCNT) and poly N-hydroxymethyl acrylamide were fabricated by a simple in situ polymerization technique. The film displays conductivities up to 10(3) S/m depending on the MWCNT loading and a sheet resistance as low as 53 Omega/square for an optical transparency greater than 95% at 550 nm. The dispersability characteristics of the suspension were determined by measuring specific surface charge, rheological behavior and UV-vis spectra. (C) 2012 Elsevier Ltd. All rights reserved.
