any one discuss the synthesis to make hollow nanofibers with polyaniline? and where to buy polyaniline higher molecular weight?
Sigma Aldrich sells it, it is quite expensive though. Polyaniline is a quite difficult polymer to electrospun, many of the problems of it is due to the lack of solubilization in good solvents for electrospinning, but you can always blend it with other polymer and make it a lot easier.
electrospinning capability is not a function of molecular weight; anyway, Mw determination as published in the literature and also by aldrich is simply wrong because people are using GPC calibrated for a PS *solution* while PAni is not soluble but dispersible, so they were using PAni dispersions running on the column which only tells you "what is the residence time on the column for which particle size fraction".
Electrospinning is best done with PAni which is optimally dispersed - the finer the particles, the higher the concentration, the better to be electrospun.
