| Abstract: | The hybrid polypyrrole-coated,aminopropyltriethoxysilane-modified fly ash cenosphere composites(PPY/APS/FACs) were successfully synthesized by in situ polymerization method.Morphology,chemical elements and thermal stability of these fresh materials were characterized by SEM,XPS and TG,respectively.The results indicate that the loading amount of polypyrrole in PPY/APS/FACs is three times more than that in PPY/FACs.Compared with PPY/FACs,the thermal stability of PPY/APS/FACs is significantly improved.In this ... |
