Actually, I need to synthesize porous 3D structure of highly conductive PAni.
In order to generate highly conductive PAni, it is not sufficient to follow an optimal synthesis route, but you need to run special *dispersion* processes; these have been described here:
Patent Dispersions of intrinsically conductive polymers
The necessary synthesis route is here:
Patent Intrinsically conductive polymer in the form of a dispersibl...
For 3D highly porous PAni (you did not say which dimensions the structure and the pores should have), I would prepare a dispersion and then freeze-dry
(still looking for a SEM photo showing the result)
B. Wessling Sir, Thank you very much for the information. I will go through it and will let you know if I have any follow-up questions.
Dear Sir, regarding porous architecture of PAni; how is freeze drying done.?
freeze-drying is done in special equipments (vacuum / very low temperature) usually provided by companies offering such service
Dear Muzamil Ahmad Khan,
Best synthesis route to prepare highly conductive PANI is the chemical oxidation route using HCl as dopant. Moreover, by using APS as oxidant and metal oxides like V2O5 as additive the porous 3D structure of PANI can be achieve.
sorry, Upendra Mahatme , that is not correct: HCl is the worst dopant you can choose, and the question was meant to seek much more detailed answers than yours; I have worked several years on HOW to run a chemical oxidation; you seem not to know that even apparently insignificant changes in the oxidation process flow are causing huge difference in the properties of the resulting PAni.
I think it is probably possible with substituted poly aniline , like o-,p, m-diamino benzenes or with aniline having NH2-Ph group as substituent which can link between polymer chains. its just my hypothesis as i felt the concept quiet interesting. But while building a 3D structure with conjugated back bone , steric and electronic constraints have to be considered.
Respected All, Thank you very much for the valuable information.

Yes, 3D type structure of PANI such as sphere, hollow sphere, balls or core shell have often been observed when oxidizing aniline in emulsion type polymerizations and/or under conditions of pH 3–4 . By varying the pH the morphology of PANI can be optimize; but to sustain the obtained structure low temperature drying is required such as Freeze drying.
