| 英文摘要 | monolithic poly(methacrylate epoxy cyclosiloxane-co-polyhedral oligomeric silsesquioxanes) (epoxy-ma-puss) capillary columns have been prepared via either photo- or thermally-initiated polymerization of the corresponding monomers using a 1-propanol/peg 400 mixture as porogens. photochemical polymerization was accomplished by irradiation of the uv-transparent capillary for 10 min at room temperature, while thermal polymerization was performed at 55 degrees c, 60 degrees c or 65 degrees c for 18 h. the evaluation of chromatographic property for two hybrid epoxy-ma-puss monoliths was carried out. the results indicate that hybrid monoliths fabricated by photochemical initiation exhibit higher column efficiency (97,000-98,400 plates/m) than those synthesized by thermal polymerization (41,100-48,000 plates/m) in clc. the higher efficiency of photo-initiated hybrid monoliths is closely related to lower eddy dispersion (a-term) and mass transfer resistance (c-term).
