Variation of the polymer structure induced by the substrate: (A) polymer film formed when the spreading of the polymer on the liquid is energetically favorable, poly(1H,1H,2H,2H-perfluorodecyl acrylate) on 1-ethyl-3-methylimidazolium tetrafluoroborate, (B) polymer particles formed under energetically unfavorable spreading conditions (poly(4-vinylpyridine) on silicone oil), and (C,D) scanning electron images of poly(4-vinylpyridine) polymer particles.
