Polymer Nanotubules Obtained by Layer‐by‐Layer Deposition within AAO‐Membrane Templates with Sub‐100‐nm Pore Diameters

The preparation and features of nanotubes consisting of various materials have attracted signifi cant attention over the past few years because of their potential applications in microelectronics, biosensors, drug-delivery systems, and many other fi elds. The layer-by-layer (LbL) deposition technique on templates has been one of the most popular methods for the formation of nanotubes. Any size and shape of template can be utilized and the desired amount of various materials including polyelectrolytes, [ 1,2 ] biomolecules, [ 3,4 ]

Discriminating Among Co-monomer Sequence Distributions in Random Copolymers Using Interaction Chromatography

Interaction chromatography has been employed to validate that adsorption of poly[styrene-co-(4-bromostyrene)] (PBr(x) S) random copolymers, where x denotes the mole fraction of 4-bromostyrene (4-BrS) in PBr(x) S in solution depends on the average number of adsorptive segments, the type of adsorbing substrate, and on the co-monomer sequence distribution in PBr(x) S.
