Preparation of transparent and conducting carbon nanotube/N-hydroxymethyl acrylamide composite thin films by in situ polymerization

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 103S/m depending on the...

Description
Summary: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 103S/m depending on the MWCNT loading and a sheet resistance as low as 53Ω/□ for an optical transparency greater than 95% at 550nm. The dispersability characteristics of the suspension were determined by measuring specific surface charge, rheological behavior and UV–vis spectra.
