PREPARATION OF CAULIFLOWER-LIKE PMMA PARTICLES AND THEIR FORMATION MECHANISM

A simple technique for preparing cauliflower-like PMMA particles by a self-formation method is proposed.PMMA particles can be obtained with tunable surface morphology by varying the polymerization time. Experimental results show that the formation of these cauliflower-like particles can be attributed to the special particle growth mechanism in the self-formation method.
