Host-guest structures with Mesoporous silica (MCM-41) and poly (diphenylamine) |
| 초록 |
Mesoporous (MCM-41) materials were synthesized using different structure directing surfactants by modifying the alkyl chains in the surfactant. X-ray diffraction (XRD) analysis and nitrogen adsorption measurements reveal that the pores are hexagonal with tunable textural properties through the choice of surfactant and experimental conditions. Diphenyl amine (DPA) was polymerized in napthalenesulfonic acid (NSA) inside the pores of MCM-41, by initial sorption of the monomer and subsequent oxidative of polymerization with peroxydisulphate. Clear presence of an additional peak (around 9-10º) in XRD pattern for the DPA loaded MCM-41 provides evidence for the existence of DPA in the pores before polymerization. PDPA formed inside the pores of MCM-41 has different electronic properties than the PDPA prepared by conventional method. N2–adsorption measurements, XRD and FTIR spectroscopic results provide evidences for PDPA entrapment in the channels of MCM-41. |
