Recent Progress on the Confinement, Assembly, and Relaxation of Inorganic Functional Fillers in Polymer Matrix during...

Functional polymer composites have gained extensive interest due to their wide range of applications. Various functionalities are mainly provided by functional fillers and their networks in polymer matrix. Therefore, morphology control on filler network has important influence on the final functionalities. The confinement, assembly, and relaxation of inorganic functional fillers in polymers are thought as the basic issues related to such control. Processing as the means to achieve the desired shape and properties for materials often involves strong temperature and shear field, among other factors-not to mention the complex interaction between polymer and filler. These processing fields and interactions during processing are reported to have profound influence on the confinement, assembly, and relaxation of inorganic fillers in polymer matrix. Therefore, various functionalities could be significantly affected by processing. This paper is a review of recent developments in this area.
