At the same time, the nanoparticles have very significant effect on the bubble nucleation and bubble growth. As a result, the research on the regulation mechanism between the nanoparticles and the morphology of microeellular foam polymer have become a hotspot in recent years. The application of nanoparticle in microcellular polymer forming process is introduced. To begin with, the preparation of several mierocellular polymer is analyzed. In addition, the adding methods of nanoparticle in the preparation of mierocellular polymer are summarized. Moreover, the influence mechanism of nanoparticles on the forming process is discussed based on the numerous research results. Finally, the foreground of research and application of the microeellular polymer is expected.
