It appears that if you oxidize aniline in the presence of SDS, you can get SDS doped PANI, with wetting properties strongly dependent on the amount of SDS presenr - see:

Dear Polyraz thanks for answer but it is well reported that CTAB can not provide the counter ions for doping and SDS can provide ...

Thank you Dr West ....

Dear Dutt,

I think Vapour phase deposition method is appeared to be suited for your synthesis. 

Dr.  Bhatt,

Thanks for your answer but I am looking for the doping mechanism using SDS and not for method. Because in acid doping e.g. HCl can provide the counter ions for doping the PANI Chain, but  in SDS how it is possible ?

Thanks Palsaniya Brother...
