Abstract
A method of dispersing nanogranules in polymer utilizing the stretching, compression, and shearing effects induced by bubble inflation or oscillation in a polymer melt undergoing foaming is reported. It can be known from theoretical calculation that the bubble inflation is very fast (about μs). The other result of theoretical calculation is that the bubble can oscillate when appearing appropriate condition in polymer. The successful dispersion of nanogranules in a polymer melt by bubble inflation has been shown by experiment. Comparison of a theoretical analysis of the dispersion effect is given by the ISBS method with the results from experimental scanning electron microscope micrographs, given reasonable grounds for support of our hypotheses.
