The liquid crystal monomers and the mixed liquid crystal materials had been purified by strong electric field. The results show that the purification has perfect effect by this method for different liquid crystal. The resistivity enhances from 10
10
cm to 10
12
cm for liquid crystal contained the ester function or the cyanogen function. The resistivity enhances from 10
11
cm to 10
13
cm for the stable structure liquid crystal contained the fluorin and benzene function.The resistivity increases evidently from 10
9
cm to 10
12
cm
or from 10
10
cm to 10
13
cm for the mixed liquid crystal. In addition
the influence of electric field strength
purified time and the liquid crystal dosage on purified effect have been investigated
respectively.
