摘要

In this study, we report on the gas permeability of non-polymerized and polymerized fullerene films (thickness about 0.5 μm) grown on an organic polymer substrate, polycarbonatesyloxane (PCS), using a high vacuum deposition method. The photopolymerized C_(60) films were prepared by a simultaneous thin film deposition and UV-vis irradiation method which was reported previously [V.A. Karachevtsev, P.V. Mateichenko, N.Y. Nedbailo, A.V. Peschanskii, A.M. Plokhotnichenko, O.M. Vovk, E.N. Zubarev, A.M. Rao, Carbon 42 (2004) 2091]. Raman spectroscopy revealed that ～90% of the C_(60) molecules are covalently linked to neighboring C_(60) molecules in the photopolymerized film after 20 h of film deposition/ irradiation. Permeability of the resulting membranes consisting of polymer PCS base and fullerene films to the N_2, O_2, CH_4, and He gases has been investigated. Our experiments revealed that the gas permeability properties are dependent on the age of the membrane. In particular, the aged membrane exhibited an enhanced permeability for O_2 and He gases in comparison to N_2 and CH_4 respectively.

Nedbailo） Peschanskii，A.M.俄克拉荷马州Plokhotnichenko E.N.沃夫克祖巴列夫（A.M.） Rao，Carbon 42（2004）2091]。拉曼光谱表明，成膜/辐照20 h后，约90％的C_（60）分子与光聚合膜中的相邻C_（60）分子共价连接。研究了由聚合物PCS基础膜和富勒烯膜组成的所得膜对N_2，O_2，CH_4和He气体的渗透性。我们的实验表明，气体渗透性取决于膜的寿命。特别地，与N_2和CH_4相比，老化的膜分别显示出对O_2和He气体的增强的渗透性。
