| 中文摘要 | fabrication of ultrathin polymer composite films with low dielectric constants has been demonstrated. octa( aminophenyl) silsesquioxane (oaps) was synthesized and assembled with poly( acrylic acid) (paa) and poly( styrene sulfonate) (pss) via a layer-by-layer electrostatic self-assembly technique to yield nanoporous ultrathin films. the oaps was soluble in water at ph 3 or lower, and suitable ph conditions for the oaps/paa and oaps/pss assemblies were determined. the multilayer formation process was studied by contact angle analysis, x-ray photoelectron spectroscopy, atomic force microscopy, quartz crystal microgravimetry, uv-vis spectroscopy, and ellipsometry. the multilayer growth was found to be steady and uniform, and the analysis of the film surface revealed a rough topography due to oaps aggregates. the incorporation of porous oaps molecules into the thin films significantly lowered their dielectric constants. the oaps/paa multilayer thin film thus prepared exhibited a dielectric constant of 2.06 compared to 2.58 for pure paa film. the oaps/paa multilayer film was heated to effect cross-linking between the oaps and the paa layers, and the transformation was verified by reflection-absorption fourier transform infrared spectroscopy. |
