In this paper. polyaniline nanostructurs with different morphologies were synthesized in medium containing ionic liquids (ILs) such as. imidazolium buthyl sulfonate [IMBS]. pyridinium chloro acetic acid [PyCAA][Cl] and pyridinium hydrogen sulfate [HPy][HSO4] with various weight ratios of aniline/ILs. https://www.seisukeknifes.shop/product-category/name-engraving-service/
