The present study describes some physical and kinetic details concerning a method for obtaining highly concentrated aqueous suspensions of few-layered graphene platelets via direct fluorinated surfactant-assisted ultrasonic exfoliation of pristine graphite. Process kinetics and qualitative properties of the product were studied using laser diffractometry, X-ray diffraction, transmission electron microscopy, electron diffraction, and Raman spectroscopy. The advantages of the described process are the ease of scalability, environmental friendliness, and high yield of few-layered graphene particles which makes it attractive for use in a wide area of applications.
