Abstract

Homogenization of the stator motor has the working principle of stirring, homogenizing, and grinding materials. Ultrasonication also has a working principle of breaking the particles with ultrasonic waves that have an acoustic cavitation effect, potentially developed into a method for producing nano-FPC. Therefore, the combination of both methods was developed to produce nanometer-scale FPC materials. The combined method of ultrasonication (5, 10, 15) min and various long-acting homogenization (5, 10, 15) minutes with homogenization speed (6,500, 9,500, 13,500, 17,500, 21,500) rpm using ultra turax T 25 basic. The results showed that with 5-minute ultrasonication able to break down the size of FPC half of its original size. The best combination of homogenization-ultrasonication treatment is the homogenizing speed of 6500 rpm for 5-minutes, and ultrasonication for 5-minutes produces nano FPC. The best homogenization-ultrasonication method is capable of producing FPC with size <100 nm.
