Abstract: It is revealed by scanning electron microscopy that the formation of filamentous structures up to 10 $\mu$m in length long can be induced in spheroplastics based on organosilicon elastomer by a shock-wave pulse of microsecond duration. Threaded structures are formed on the surface of fractured microspheres. Their formation is facilitated by the metallization of the surface of glass spheres. The results of an experimental study of changes in the dielectric and mechanical characteristics of metallized spheroplastics, caused by impact-wave action, are presented. Possible reasons for the formation of threaded structures upon a shock-wave impact on spheroplasics are discussed.
Keywords: shock wave, spheroplastic, microspheres, glass spheres, nanowhiskers, dielectric properties, mechanical properties.
