| 英文摘要 | Polymer/inorganic hybrid materials were prepared by supercritical carbon dioxide (scCO(2)) impregnation. Tetraethyl orthosilicate (TEOS) was infused into polypropylene (PP) strips in scCO(2) using ethanol as the co-solvent. The effect of this co-solvent on mass uptake was investigated. We found that the mass uptake of TEOS into PP strips increased to a maximum and then decreased after the addition of more co-solvent. The effects of other impregnation conditions on the mass uptake were also investigated with using ethanol. Moreover, the depth profile of the infused elements inside the polymer/inorganic hybrid material was obtained by Rutherford backscattering spectrometry (RBS). The RBS spectrum demonstrated that the concentration of Si in the PP strips was not uniform and decreased with infusion depth. |
