    Abstract
  • To obtain suspended dispersion of nano-particles in liquid without any dispersant, a novel epoxy resin/SiO 2nanocomposites preparation method based on diminutive bubbles explosion is presented. And, corresponding nanocomposites preparation system was designed. The preparation system applies compressed gas as transmission medium to carry nanomaterials into epoxy resin solution. The compressed gas with nanomaterials turns into diminutive bubbles distributing in epoxy resin/SiO 2. The great pressure difference between inner and outer-bubbles led to bubbles inflation and explosion. During the bubble inflation, bubble oscillation may generate. The stretching rate may reach 10 6s -1, which favors more homogeneous dispersion of nano- particles. During the bubbles explosion the released energy and the explosion shock waves disperse the nano- particles into epoxy resin solution. By using the preparation system, epoxy resin/SiO 2nanocomposites were prepared. The SiO 2dispersed into epoxy as the configuration of 15nm-30nm particles.
