摘要
The surface modification with titanate coupling reagent (NDZ-105) of nano-β-carborundum whisker (β-SiCw) was studied. Static precipitation method was used to analyze the dispersion stability of nano-β-SiCw before and after modification, the curve of zeta potential versus pH is measured to show the potential nature of the β-SiCw surface, and the prepared samples were characterized. Results showed that the NDZ-105 was bound onto the surface of nano-β-SiCw, a firm chemical bonding of NDZ-105 to nano-β-SiCw film and an organic layer was formed. Modified nano-β-SiCw changed from hydrophitic to lyophobic. Mechanical tests revealed that the strength and toughness of the nano-β-SiCw modified with NDZ-105 were improved simultaneously.
