Sonochemical Preparation of Polymer Microcapsules

Article Preview

Abstract:

Polymer microcapsules have important application in the fields of biochemistry and materials science owing to their unique structures and functions. Poly(styrene-methyl methacrylate) (PS-co-PMMA) microcapsules were prepared through sonochemical method. The results reveal that it is difficult to form a microcapsule structure from neat styrene (St). However, MMA can improve the interface condition for its higher hydrophilicity. Therefore, it is easier to form hollow structure because polymer microcapsules have a lower interface free energy per unit area. FTIR results confirm that polymer microcapsules have both the typical peaks of PS and PMMA. The results of dynamic light scattering (DLS) and TEM show that PS-co-PMMA microcapsules are uniform in size(about 100 nm in diameter and 20~25 nm in shell thickness).
