Modified main groups metal oxides as potential active fillers for polymers

Polimery 2006, No 2, 115


Summary

The demand for polymers exhibiting special properties has necessitated the modification of metal oxide polymer fillers currently in use to obtain adequate filling characteristics. Recent developments in the literature (also from the authors), in which the advantages of the applications of metal oxides as polymer fillers with special consideration of the dependence of their properties on origin and thermal treatment are presented. The acid-base and donor-acceptor properties of this group of fillers and also the dependence of their properties on electronic parameters is discussed in detail. The use of practical methods of oxide modification, such as precipitation, coprecipitation, gelation and impregnation is further discussed. The importance of defects in the oxide structure and the acidic properties resulting from their activity is presented. The possibility of application of these oxides in synthesizing organic/inorganic hybrid materials is also discussed.


Key words: polymer fillers, metal oxides, methods of preparation, modification, acid-base properties, donor-acceptor properties, structural defects, hybrid materials
