Microscale Polymer-Nanotube Composites



Erik K. Hobbie, Jeffrey A. Fagan, Jan Obrzut, Steven D. Hudson


Microscopic polymer colloids with an interfacial coating of purified single-wall carbon nanotubes (SWCNTs) have been synthesized from length and type sorted SWCNTs. Aqueous SWNCT suspensions sorted through density-gradient ultracentrifugation are used to emulsify spherical polymer colloids of microscale dimensions that are then characterized through a combination of optical microscopy, transmission-electron microscopy and impedance spectroscopy. The SWCNT-polymer composite particles achieve electrical conductivities better than bulk SWCNT-polymer composites at nanotube loadings that are more than an order of magnitude smaller. The particles retain the unique optical and electronic characteristics of the parent SWCNT solution with potential applications as micro-optical and microelectronic components.
