In this study, after establishing the condition that has the optimum ultrasonic wave totransform the fine structure of PMMAusing the ultrasonic wave, the controlling particle size and modifying a surface of the PMMA microspherewere tried. ThePMMAwas manufactured by the suspension polymerization using an initiator and then the surface was rough and it obtained the microsphere of the average particle size of 30μm. The process thathas the ultrasonic wave modified the surface, and its surface could be smooth and the microsphere of the average particle size 10μm can be manufactured. |
