Surface Modification of Mesoporous Silica via Grafting of Poly(acrylonitrile) and its Pyrolysis |
| 초록 |
We prepared hexagonally ordered mesoporous silica from an amphiphilic organotriethoxysilane containing a thermally cleavable urethane moiety and tetraethoxysilane (TEOS) using a cationic surfactant as a template. The ATRP initiator was introduced into mesopores utilizing thermally cleavable bond and acrylonitrile was polymerized inside the pores. The resulting poly(acrylonitrile) nanofibers were carbonized at 700 °C under nitrogen. Surface modification inside the pore with carbon source showed higher adsorption for hydrogen storage comparing with original mesoporous silica particle. |
