Abstract

ABSTRACT: We introduced the preparation of hybrid composites using technical cellulose as a matrix material from rice husks with a natural SiO2 content from 0% to 19.4%. In this work, the physicochemical characteristics of the resulting hybrid composites have been investigated. The presence of SiOC chemical bonds in the resulting hybrid composites was determined by infrared spectroscopy. Microscopic analysis showed the complete removal of the mineral component and lignin from the cell wall of the rice husk fibers. This allows obtaining of an expanded surface of the fibers (101.7 m 2 /g) with uniform distribution of the TiO2 aggregates. It could be shown that with content increasing of natural silicon dioxide in the hybrid composite the decomposition rate of H2 O2 also increases. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.
