A flexible cross-linked multi-walled carbon nanotube paper for sensing hydrogen

Here we report on the construction and operation of a cross-linked aminated multi-walled carbon nanotube paper as a hydrogen sensor. The incorporation of palladium onto the surface of the paper resulted in p-type conduction as the resistance of the paper was measured, under exposure to hydrogen gas....

Description
Summary:Here we report on the construction and operation of a cross-linked aminated multi-walled carbon nanotube paper as a hydrogen sensor. The incorporation of palladium onto the surface of the paper resulted in p-type conduction as the resistance of the paper was measured, under exposure to hydrogen gas. When palladium nanocrystals were embedded into the cross-linked paper, n-type conduction was observed during hydrogen sensing. This investigation highlights the next stage in the development of functional nanotube paper.
