Abstract
Periodic mesoporous organosilicas (PMO) were synthesized using bis(triethoxy silyl) ethane (BTEE) as the precursor and dodecyl trimethyl ammonium bromide(DTMA), cetyl trimethyl ammonium bromide(CTMA), and octadecyl trimethyl ammonium bromide(ODTMA) as the templating agents. The surface area and pore volume of PMO decrease with the increasing of chain length of templating agents. However, the chain length of templating agents almost has no effect on the pore diameter of PMO. From the XRD and the DSC experiments, we found that the chain length of surfactants using as the templating agents has an effect on the melting transition of polyethylene. But it has no effect on the melting transition of poly(ethylene oxide). The results of TGA prove that the thermal decomposition temperature of polymer which was penetrated into PMO was increased.
