Electric Field-Driven Assembly of Sulfonated Polystyrene Microspheres
A designed assembly of particles at liquid interfaces offers many advantages for development of materials, and can be performed by various means. Electric fields provide a flexible method for structuring particles on drops, utilizing electrohydrodynamic circulation flows, and dielectrophoretic and electrophoretic interactions. In addition to the properties of the applied electric field, the man...
متن کاملNMR Analysis of Sulfonated Polystyrene
Atactic polystyrene (PS) has an amorphous structure. Compounds such as H2SO4 and SO3 are commonly used as sulfonating agents for various polymers, including PS. The main purpose of this work is to study chemical structural changes in PS arising from sulfonation through DSC analysis and NMR spectroscopy. An increase in the glass transition temperature (Tg) of sulfonated polystyrene and a decreas...
متن کاملAtomistic simulations of the structure of highly crosslinked sulfonated poly(styrene-co-divinylbenzene) ion exchange resins.
The microscopic structures of highly crosslinked sulfonated poly(styrene-co-divinylbenzene) resins have been modeled by generating atomistic microstructures using stochastic-like algorithms, which are subsequently relaxed using molecular dynamics. Two different generation algorithms have been tested. The relaxation of the microstructures generated by the first algorithm, which is based on a hom...
متن کاملPreparation and physical characterization of a sulfonated poly(styrene-co-divinylbenzene) and polypyrrole composite membrane
The properties of cation-exchange membranes based on polymeric composites of sulfonated poly(styrene-co-divinylbenzene) and polypyrrole (Ppy) are discussed. The amount of Ppy in the composites depends on the oxidant solution concentration used in the synthesis. Comparing composite membranes, the highest electronic conductivity and the best thermal stability were obtained for the composite membr...
متن کاملPolystyrene-co-Divinylbenzene PolyHIPE Monoliths in 1.0 mm Column Formats for Liquid Chromatography
The reversed phase liquid chromatographic (RP-HPLC) separation of small molecules using a polystyrene-co-divinylbenzene (PS-co-DVB) polyHIPE stationary phases housed within 1.0 mm i.d. silcosteel columns is presented within this study. A 90% PS-co-DVB polyHIPE was covalently attached to the walls of the column housing by prior wall modification with 3-(trimethoxysilyl) propyl methacrylate and c...
