Abstract
Monodisperse hollow hexanitrostilbene-piperazine compound microspheres were fabricated successfully through a facile one-pot procedure based on the reaction of hexanitrostilbene (HNS) and piperazine without any template or surfactant. Synthesis conditions (ratio of reactants, stirring rate, reaction temperature and time) have been optimized to obtain compound microspheres with good monodispersion and narrow size distribution. And the results indicated that as-obtained microspheres possessed central hollow structures. Moreover, a possible formation mechanism for assembling hollow compound microspheres was proposed. This work may introduce a novel idea towards designing and fabricating the new hollow spheres materials.
