Environment friendly dual-frequency ultrasonic exfoliation of few-layer graphene (2021)
Journal Article
Tyurnina, A. V., Morton, J. A., Subroto, T., Khavari, M., Maciejewska, B., Mi, J., …Eskin, D. G. (2021). Environment friendly dual-frequency ultrasonic exfoliation of few-layer graphene. Carbon, 185, 536-545. https://doi.org/10.1016/j.carbon.2021.09.036Ultrasound-aided liquid phase exfoliation (ULPE) of graphene in pure water is environment-friendly. Two limiting factors of ULPE are the non-uniform thickness of few-layer graphene (FLG) and a relatively low graphene yield. Here we describe ULPE in w...
