| Outline of Final Research Achievements |
This study provided a fundamental technique of fabricating metallic nanocoil (NC) networks. The technique for mass-fabricating metallic NCs by assisting the release of residual stress, was originally developed by our research group, is referred to as “mechanical self-assembly”. Thermal decomposition of electrospun resin nanofibers (NFs) was used for releasing the inhomogeneous residual strain in the biased thick metal film coating on the NF. The process conditions were optimized to reduce the coil diameters down to around 1 micrometer. Transparent resin films containing Pt NC networks ware demonstrated for stretchable electrode and electromagnetic wave absorber, which would contribute to the information-technique-based society with safety.
