Another group of data also supports the synergy effect of the synthetic process, that it generates materials with new properties and potential applications. When SiO2 nanoparticles were chemically bonded on the surface of the cellulose fibers the thermal stability of these fibers was improved. Even a reduction of up to 50% in the moisture adsorption capacity of the modified cellulose fibers was observed . Although these study hybrid composites were produced by a very facile synthesis, its thermal behavior shows very competitive performance.
