Preparation and Characterization of Thermally Expandable Microcapsules by In Situ Polymerization

Article Preview

Abstract:

In the present work, we synthesized microcapsules with copolymer of acrylonitrile and ethyl acrylate as shell and isooctane as core by in situ polymerization, and then optimized the preparative method. Synthesized microcapsules were characterized by Fourier transform infrared spectroscopy (FTIR), 13C nuclear magnetic resonance (13C-NMR), scanning electron microscopy (SEM), particle diameter analysis and thermogravimetry (TG).
