Synthesis and Properties of Acrylate Nanocomposites

Abstract

Well-dispersed (exfoliated) PMMA nanocomposites were synthesized via emulsion polymerization. The nanocomposites retain their transparency in the visible with the montmorillonite nanocomposite showing considerable absorption of Uv light. Thermal stability of the nanocomposites is enhanced as evidenced by TGA and a simple burning experiment. The storage modulus and Tg is increased significantly in the nanocomposites. The higher increase of the storage modulus in the rubbery regime of the montmorillonite nanocomposite reflects the higher amount of bound polymer compared to the fluorohectorite nanocomposite. End-tethering of PMMA to the silicate surface increases the amount of bound polymer and results in increases in both Tg and modulus in the rubbery plateau
