Triblock, diblock and random copolymers of poly(ethylene oxide) and poly(propylene oxide) are used as molecular templates in poly(methyl silsesquioxane) (MSQ) matrices to fabricate ultra low-k dielectric materials (kp2:0). Solidstate NMR shows that polymer architecture plays an important role in the polymer domain size and the polymer– matrix interface in the nanocomposites. Positronium annihil...
This paper briefly reviews the fabrication and electrorheological (ER) characteristics of mesoporous materials and their nanocomposites with conducting polymers under an applied electric field when dispersed in an insulating liquid. Smart fluids of electrically-polarizable particles exhibit a reversible and tunable phase transition from a liquid-like to solid-like state in response to an extern...
Yittrium iron garnet, Y3Fe5O12 (YIG), is a material used widely in electronic devices for the microwave region as well as the magnetic bubble domain-type memories. Yittrium iron garnet (Y3Fe5O12) was produced by mechanochemical synthesis from Y2O3 and Fe2O3 with particle size of around 150 nm. PMMA/YIG composite films were prepared by solution casting method at diffferent concentration (i.e. 10...
Eu ions and elliptical Au nanoparticles incorporated new antimony based reducing dielectric (here glass) matrix, K2O-B2O3-Sb2O3 (KBS), has been prepared by a new single-step methodology involving selective thermochemical reduction without employing any external reducing agent. X-ray diffraction (XRD) and selected area electron diffraction (SAED) results of these hybrid nanocomposites indicate t...
