Chemically synthesized Poly aniline nano particles are found to be insoluble in most of the organic solvents.Can anyone please suggest me some methods for improving the processability of poly aniline?
If you need to prepare the stable polyaniline (PANI) dispersions, I guess to make PANI coating, this book can be very helpful to find references or information about synthetic procedure. There is a separate chapter about PANI.

Natalyia's answer is good enough. You can try making polyaniline dispersions using poly(vinyl methyl ether), poly(vinyl alcohol) or cellulose ethers as dispersant. Some refs. are: Macromolecules 1995, 28, 3940; Polym. Intl 2001, 50, 538.
As you have seen from the above advices there are different approaches to bypass PANI processibility problem. But I think that our old review " Some aspects of preparation methods and properties of polyaniline blends and composites with organic polymers, Prog. Polym. Sci. 28 (2003) 1701–1753" will be also useful in the matter
