thermoelectric properties and performance of flexible reduced graphene oxide films up to 3,000 k - flexible film
Development of ultra-high power technology
The temperature thermoelectric material can realize the thermoelectric top of the combustion power cycle and expand the range of centralized solar direct thermoelectric power generation.
However, due to the lack of suitable materials, the thermoelectric operating temperature is limited to less than 1,500 k.
Here we show a high-based-
Graphene oxide nano sheet with reduced temperature can reliably work up to 3,000 k.
In 3,300 u2009 K under reduction processing after nano-thin film in 4,000 u2009 K under Show ~ The conductivity of the 3,000 ss cmcm-1 increased, and the power factor s2 σ = 54. 5u2009µWu2009cm−1u2009K−2.
We report the measurement results that characterize the thermoelectric properties of the film up to 3,000 k.
The reduced graphene oxide film also has a high broadband radiation absorption capability and can be used as a radiation receiver and a thermoelectric generator.
Printable, lightweight, flexible films appeal to system integration and scalable manufacturing.
