Hello Wasihun,
The reason of using CCl4 I think related to its transparency and IR peaks. For recording UV spectra the solvent used must be transparent, also for IR spectroscopy the solvent peaks should not overlap with the adsorption peaks of the compounds you are after. With this, regard nonpolar solvent e.g. CCL4 and CS4 have used. The solvent also play a role in determining the dipole moment of the conducting polymer e.g. polypyrrole In NMR analysis
I hope it will help

Liquid carbon tetrachloride is a nonelectrolyte (i.e. it does not conduct electricity) for obvious reasons which are the nonpolar character of its molecules & the incapability to form ions by itself or in water "under normal conditions".
When a polymer is in CCl4 , the medium has to be nonconducting to detect conductivity from the polymer only in the "usual" measurements.
Thank you both of you for relevant information, here I have one request can you share the reference on that or any Paper which talk about this?
