聚砜/碳纳米管复合膜的介电性能

Dielectric Properties of Polysulfone Carbon Nanotube Composite Membranes

Bhakti Hirani, P. S. Goyal, Deepali Shrivastava, S. K. Deshpande

摘要:

聚合物膜,包括聚砜(PSf)膜,通常用于水处理。为了增强上述膜的水渗透性,通常合成具有嵌入其中的碳纳米管(CNTs)的聚合物膜。可以看出,具有垂直排列的CNT的膜的水渗透性比CNT未排列的膜高。研究基于CNT的纳米复合膜的介电常数是否对CNT的取向敏感是有意义的。本文报道了PSf-MWCNT膜的介电性能,无论是对齐和未对齐的MWCNT。使用标准方法合成基于多壁碳纳米管(MWCNT)的聚砜膜。通过在磁场存在下浇铸膜来排列上述膜中的MWCNT。本文首次证明了上述结果对膜也是有效的。

英文摘要:

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.
