Abstract
Systems and methods for treating small elongated fibrous and particles of certain materials, e.g., PTFE materials in a suspension are presented. In some instances, high-intensity ultrasound (or acoustical energy) is applied to a sample of the material, through a fluid coupling medium or suspension, to achieve a material transformation in the sample. In various embodiments, fibrillation of particles of PTFE or similar materials is accomplished, or the formation of extended structures of these materials is caused or enhanced. Also, the ability to separate long fiber samples by ultrasonic or acoustic cavitation action is provided.
