论文摘要
聚合膜（包括多硫酮（PSF）膜）通常用于水处理。为了增强上述膜的渗透，通常将聚合物膜与嵌入其中的碳纳米管（CNT）合成。可以看出，与未对齐的CNT相比，具有垂直排列的CNT的膜的水渗透性更高。有趣的是检查基于CNT的纳米复合膜的介电常数是否对CNT的比对敏感。本文报道了PSF-MWCNT膜的介电特性，包括对齐和未对准的MWCNT。使用标准方法合成了基于多壁碳纳米管（MWCNT）的多硫酮膜。通过在存在磁场的情况下铸造膜来对齐上述膜中的MWCNT。本文首次表明上述结果也对膜有效。
Polymeric membranes, including Polysulfone (PSf) membranes, are routinely used for water treatment. To enhance water permeation of above membranes, it is common to synthesize polymeric membranes with carbon nanotubes (CNTs) embedded in them. It is seen that water permeability of membranes having vertically aligned CNTs is higher, as compared to those where CNTs are not aligned. It is of interest to examine if the dielectric constant of a CNT based nanocomposite membrane is sensitive to alignment of CNTs or not. This paper reports dielectric properties of PSf-MWCNT membranes, both, for aligned and unaligned MWCNTs. Multi Walled Carbon Nanotubes (MWCNTs) based polysulfone membranes were synthesized using standard methods. MWCNTs in above membranes were aligned by casting the membrane in presence of magnetic field. The present paper, for the first time, shows that the above result is valid for membranes also.
