ABSTRACTHexagonally mesostructured 12-phosphotungstic acid (PWA) thin films with both large pore size and hierarchical structures have been successfully prepared by using triblock copolymer templates for the first time. The films is composed by three kind of structures; PWA Keggin anion, monoclinic crystal structure consisting of PWA Keggin anion and organic part (hydrophilic component) of block copolymers, and the hexagonal mesostructure of self-arrayed PWA and block copolymers. The calcined PWA films show better electrochemical properties such as a faster faradic processes and larger specific capacity than normal P WA clusters.

The behavior of amphiphilic block copolymers in solution has attracted considerable attention in recent years. In this paper, the self-assembly behaviors of the amphiphilic fluorinated ABC-type triblock copolymer (MeOPEO16-PSt220-PFHEA22) in different mixed solutions were studied. Also, the effect of ionic concentration on the self-assembly aggregates of the copolymer in toluene-ethanol-water was studied.

Radical copolymerization of a mixture of styrene (S) and acrylonitrile (AN) at azeotropic composition (63 mole % of S and 37 mole % of AN) at 125 °C in the presence of dibenzoyl peroxide and 2,2,6,6-tetramethylpiperidin-1-yloxyl (TEMPO) gave TEMPO-terminated S-AN copolymers with narrow molecular weight distributions. Both the linear semilogarithmic time-conversion and molecular weight-conversion dependences indicated a quasiliving copolymerization process. Polymerization of styrene initiated with the synthesized macroinitiators containing reversibly bound terminal TEMPO groups yielded film-forming poly(styrene-co-acrylonitrile)-block-polystyrene copolymers. Using the resulting diblock copolymer as a macroinitiator in copolymerization of S and AN, a triblock copolymer of the A-B-A type was obtained. Films of the block copolymers were prepared by casting chloroform solutions and their permeabilities (P) to nitrogen, oxygen, methane, carbon dioxide, and hydrogen were determined. The films showed high selectivities to oxygen (PO2/PN2 > 6). The block copolymers behaved as single-phase homogeneous materials.

The use of methylhydroquinones enables the preparation of block copolymers having phenylene rings with precisely 2, 3 or 4 quaternary ammonium groups. Membrane properties show the importance of controlling the local ionic distribution to reach high anion conductivity.
