Modulation of refractive index in polymer composites: toward a synthetic bio-optic lens
(SPIE: Proceedings of SPIE, 2003-07)
As an option in the creation of a synthetic bio-optic lens, we propose that spatial modulation of refractive index can be realized in polymer composites containing a colloidal ionophoric phase. The variation of refractive ...
Dielectric spectroscopy of polystyrene/poly(ethylene oxide) composites
(American Chemical Society: Macromolecules, 1996-07-01)
The effect of incorporating poly[styrene-b-(ethylene oxide)], PS-b-PEO into PS/PEO composites has been examined microscopically and dielectrically. The addition of block copolymer stabilizes the dispersion of PEO in PS and ...
Dielectric spectroscopy of binary polystyrene/poly[styrene-b-(ethylene oxide)] blends and ternary composites of polystyrene/poly[styrene-b-(ethylene oxide)] swollen with homopoly(ethylene oxide)
(American Chemical Society: Macromolecules, 1996-07-01)
The effect of incorporating poly[styrene-b-(ethylene oxide)], PS-b-PEO into PS/PEO composites has been examined microscopically and dielectrically. The addition of block copolymer stabilizes the dispersion of PEO in PS and ...
Effect of crystallization on the morphologies of block copolymer/homopolymer blends cast in an electric field
(Wiley: Journal of Polymer Science Part B: Polymer Physics, 1996-01-30)
Blends of polystyrene (PS) and poly(styrene-b-ethylene oxide) (PS-b-PEO) were cast from a ternary solvent mixture containing 85% toluene, 10% tetrahydrofuran, and 5% methanol under conditions that favor crystallization of ...
Effect of block copolymer on the electric field induced morphology of polymer blends
(American Chemical Society: Macromolecules, 1991-12-23)
Voltammetric determination of the ion-exchange behavior of poly(ester sulfonic acid) anionomers in acentonitrille
(The American Chemical Society: Analytical Chemistry, 1990-10-01)
Synthesis and molecular structure of the eight-coordinate complex bis( 4-amino-N,N’-disalicylidene- 1,2-phenylenediaminato)zirconium( IV), a new reagent for preparing coordination polymers
(The American Chemical Society: Inorganic Chemistry, 1987-12-30)
The precursor complex bis(4-nitro-N,N’-disalicylidene- 1,2-phenylenediaminato)zirconium(IV);Zr(ndsp)2, was synthesized from the appropriate Schiff-base ligand and zirconium tetra-n-butoxide butanol complex (2:1, respectively) ...
A soluble linear Schiff-base coordination polymer containing eight-coordinate zirconium (IV)
(The American Chemical Society: Macromolecules, 1985-07)
The first soluble linear Schiff-base heavy-metal coordination polymer has been synthesized via the condensation of 1,2,4,5-tetraaminobenzene and tetrakis(salicylaldehydato)zirconium(IV) in dry dimethyl sulfoxide. The (N, ...
Functional polymers in the generation of colloidal dispersions of amorphous selenium
(American Chemical Society: Macromolecules, 1980-09)
Stable colloidal dispersions of red, amorphous selenium have been prepared by the reduction of selenious acid in dilute aqueous solutions of hydrazonium polyacrylate. The initially formed particles average 1000-1200 A, in ...
Colloidal iron dispersions prepared via the polymer-catalyzed decomposition of iron pentacarbonyl
(American Chemical Society: Journal of Physical Chemistry, 1980-06-12)
Stable colloidal dispersions (50-150 A) of zero-valent iron have been prepared by the thermolysis of Fe(CO)5 in dilute solutions of “functional” polymers. The formation of these colloidal dispersions has been rationalized ...
