Abstract
Stable ultrathin transparent conductive carbon nanotube (CNT) micropatterns were fabricated from photosensitive polymer diazoresin (DR) and carboxylic acid-modified CNT (COOH-CNT) using a layer-by-layer (LBL) self-assembly technique. The CNT micropatterns were realized on LBL ultrathin film after UV exposure through a photomask and development in aqueous solution of sodium dodecylsulfate (SDS). The CNT patterns were characterized systemically with scanning electron microscopy, atomic force microscopy, UV-vis spectroscopy and four-point conductivity measurement system. All of the results indicate that the combined LBL self-assembly and photolithography technique is a promising method for constructing stable transparent conductive CNT micropatterns with nanoscale thickness.
