Based on aligned multi-walled carbon nanotubes (MWCNTs), a highly stretchable and conductive polydimethylsiloxane (PDMS)/ MWCNTs composite fiber has been fabricated through a simple, effective and environmental friendly method. The prepared fiber shows excellent stretchability (up to 360% strain) and conductivity (4 S/m) with only around 2wt% of MWCNTs. In addition, the prepared fiber exhibits increased conductivity under tensile strain and cyclic stretching, which makes it an interesting candidate for a wide variety of applications in electronics. An application as conductive wires demonstrates that the prepared fiber will provide a new possibility for the development of next generation electronics.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
