Abstract
The present disclosure relates generally to processes for preparing metal oxide nanosheets. In particular, the process may comprise generating a liquid metal film comprising a metal oxide surface layer, and exfoliating the metal oxide surface layer to form a metal oxide nanosheet. The present disclosure also relates generally to devices comprising the metal oxide nanosheets, such as piezoelectric generators and sensors.
Claims32
A process for preparing a metal oxide nano sheet, comprising the steps of:
- a) heating a metal that is provided on a supporting substrate to a temperature effective to melt the metal to generate a liquid metal film on the supporting substrate,
- b) contacting the liquid metal film with an oxygen atmosphere to generate a metal oxide surface layer on the liquid metal film, and
- c) contacting the metal oxide surface layer with a target substrate, and exfoliating the metal oxide surface layer from the supporting substrate to form a metal oxide nanosheet layer on the target substrate.
