Paper Abstract

This paper demonstrated the physical properties of a layer-by-layer (LBL) assembled single-walled carbon nanotubes (SWNTs) - polymer composite thin film. The superior mechanical and electrical properties that originate from SWNTs were successfully incorporated into a polymeric thin film by hydrogen bonding-directed LBL assemblies. The electrical conductivities and mechanical strength of a LBL composite are 8.5*103 S/m and 160 MPa with only 8±2wt% SWNT loading. The combination of high electrical and mechanical properties of SWNT-polymer LBL thin films makes this material unique, opening the way for a wide range of applications from flexible electronics to space telescopes and biomedical implantable devices.
