Abstract:
1. Flexible hydrogen sensors, comprising: high temperature chemical vapor deposition (CVD) single-walled carbon nanotubes (SWNTs) with clean surfaces; flexible plastic substrates for supporting said SWNTs; palladium (Pd) nanoparticles on said SWNTs, said Pd nanoparticles being spaced from each other to form individual discontinuous Pd nanoparticles rather a continuous Pd film; two metal electrodes of gold, said gold electrodes being positioned on SWNTs and said gold electrodes being spaced and separated from each other; said gold electrodes arc covered and coated with no Pd nanoparticles are deposited on said gold electrodes because said gold electrodes are covered with said SiO said SWNTs and said Pd nanoparticles having variable resistance for conversion and amplification into electrical signals; said SWNTs and Pd nanoparticles cooperating with each other to provide high-performance flexible hydrogen sensors for sensing hydrogen; and said high-performance flexible hydrogen sensors being bendable for conforming and complementing contours of other structures while substantially maintaining performance.
