Abstract Scope Ultrasound assisted liquid phase exfoliation is a promising method for manufacturing 2D materials. Understanding the effect of ultrasonication parameters such as temperature and input power on the developed pressure field is pivotal for optimisation of the process. Limited research has been carried out to determine the optimal temperature for exfoliation, with some data generating disputed results. Simply maximising sonication power does not necessarily produce higher yield due to shielding. In this study, a high-temperature calibrated cavitometer was used to measure the acoustic pressure generated in different graphite solutions in deionised water at various temperatures (10-70 ℃) and input power conditions (20-100%). In addition, high-speed optical imaging revealed insight on shock wave generation from transient bubble collapses in different sonication conditions. The optimal sono-exfoliation parameters were determined using 20% input power in 10 ℃ for a graphite flake solution, and 100% input power in 40-50 ℃ for a graphite powder solution.
