ABSTRACT
A number of synthetic methods have been developed to synthesize graphene-templated Palladium nanostructures, such as the laser reduction method, plasma-assisted reduction and sacrificial Cu template-mediated method. Few-layer graphene nanosheets were derived from the dispersion and exfoliation of graphite powder in N-methyl-pyrrolidone by using moderate ultrasonic treatment. Hybrids based on graphene or graphene oxide and other nanocarbons, such as carbon nanotubes (CNT) and carbon nanofibers, have become a new group of carbon-based materials. Hybrids with different ratios of acid- multi-walled carbon nanotubes (MWCNTs) and graphene were prepared to optimize the dispersion behaviors of the hybrids. A similar method was used to prepare a paper-like hybrid from few-layer graphene and MWCNTs. The heterostructure consisted of a graphene layer on top of the CNT arrays on substrates, which could be transferred to various polymer substrates and demonstrated observable sensitivity in terms of electrical conductivity in both tension and compression conditions.
