Synthesis and applications of hollow particles

Abstract

Hollow particle is a promising material with the special properties of low densities, thermal insulation and distinct optical activity. Due to their potential promising applications in the fields of drug delivery, catalysis and optics, a great effort has been devoted to develop new preparation methods which are collected and reviewed in this paper. All these methods are classified into three groups, namely sacrificed template method, in-situ template method and device-based method based on the characteristics of the methods. The advantage and disadvantage of each method are compared and the trends for preparation are pointed out. In light of the wide applications of hollow particles, the later part of this paper focuses on their potential applications in industry. Their applications are not limited in the fields of papermaking, rubber processing and plastic improvement, but also expanded to electronic, catalytic and biological areas. © 2013 Hosokawa Powder Technology Foundation.
