摘要：

The surface of nanosized fumed silica (FSi) was modified with different amine groups by the use of silylating agents. The obtained propylamine, propylpiperazine, and propyl-pphenylenediamine modified FSi were treated with different sulfonyl chlorides to gain sulfonamide-modified FSi compounds. These compounds were characterized by various techniques including Fourier transform infrared spectroscopy, thermogravimetric analysis, differential thermal analysis, scanning electron microscopy, and energy-dispersive X-ray spectroscopy (EDX), confirming the grafted sulfonamides on the FSi surface. Sulfonamide modified surfaces are efficient catalysts for the Michael addition-based syntheses and coupling reactions. Furthermore, the antibacterial tests showed that these modified FSi compounds have antibacterial activities and thus are useful materials for preparing antibacterial silicone-based compounds such as silicone glue and oil.
