Abstract

The effect of single-walled carbon nanotubes (SWCNTs) on the dielectric and conductivity properties of smectic A liquid crystal 4-nitrophenyl-4'- decyloxybenzoic acid has been studied. It was shown that the additive of SWCNTs with concentration of 0.5% leads to a decrease in the order parameter of the liquid crystal. In this case, the clearing point and the longitudinal component of the dielectric permittivity decreases while the transverse component increases. The incipient percolation effect promotes to the dominance of hopping electron conductivity over ionic conductivity, leading to an increase in specific conductance.

掺杂SWCNT的近晶液晶的有序参数和高电导率的降低。

摘要

单壁碳纳米管（SWCNTs）对近晶电介质和电导率性能的影响研究了液晶4-硝基苯基-4'-癸氧基苯甲酸。结果表明，浓度为0.5％的SWCNT的添加会导致液晶顺序参数的降低。在这种情况下，介电常数的清除点和纵向分量减小，而横向分量增大。初期的渗透作用促进了跃迁电子电导率超过离子电导率，导致比电导率增加。
