J. Ruokolainen et al., DIRECT IMAGING OF SELF-ORGANIZED COMB COPOLYMER-LIKE SYSTEMS OBTAINEDBY HYDROGEN-BONDING - POLY(4-VINYLPYRIDINE)-4-NONADECYLPHENOL, Macromolecules, 31(11), 1998, pp. 3532-3536
Comb copolymer-like systems obtained by hydrogen bonding between flexi
ble polymers and nonmesogenic amphiphiles represent a class of supramo
lecular materials with interesting self-organizing properties. Here we
present the first results of transmission electron microscopy applied
to mesomorphic systems of poly(4-vinyl pyridine)-4-nonadecylphenol as
a characteristic example. Phase contrast imaging of iodine-stained sa
mples Confirms the highly ordered lamellar structures with a long peri
od of around 40 Angstrom inferred also from small-angle X-ray scatteri
ng data.
