Conducting polymeric polyaniline hollow spheres (PANI-HS) were fabricated and evaluated as a smart electro-stimuli responsive material, whose both special structure of shorter diffusion length promotes the electron transfer and specific surface area is greatly amplified than solid spheres. The monodisperse polystyrene (PS) seeds were initially synthesized by a facile surfactant-free emulsion polymerization,...
Core-shell structured conducting polyaniline (PANI)-coated polystyrene (PS) composite nanospherical particles were synthesized and assessed as a candidate for electrorheological (ER) materials. Monodisperse PS nanospheres were initially synthesized by a dispersion polymerization process and their surface was modified using concentrated sulfuric acid. This allowed the aniline monomer to be adsorbed...
We synthesized Fe3O4/polystyrene (PS) composite nanoparticles via a Shirasu porous glass (SPG) membrane emulsification technique and examined their magnetorheological (MR) properties under external magnetic field strengths. The SPG method was adopted for achieving a narrow size distribution of the product nanoparticles containing magnetite. The structure and morphology of the samples were analyzed...
Wholly aromatic poly(aryl ether ether nitrile)s containing naphthalene structure with sulfonic acid groups meta to ether linkage (m-SPAEEN), intended for fuel cells applications as proton conducting membrane materials, were prepared via nucleophilic substitution polycondensation reactions. The incorporation of rigid naphthalene structure with meta-sulfonic acid groups was with the intent of improving...
Ionomer–silica hybrid materials were made from polyethylene-co-acrylic acid neutralized by a zinc salt (PI) and tetraethoxy silane (TEOS) via the sol–gel reaction. The effects of various experimental parameters such as solvents, H 2 O/Si ratio and the amount of TEOS in the ionomer solution on the hybrid structure and properties were examined. The spectroscopic results show that solvents do...
Isothermal melt crystallization in poly(butylene terephthalate) (PBT) homopolymers and glass-fiber-filled composite was studied by time-resolved simultaneous small- and wide-angle X-ray scattering (SWAXS) methods using synchrotron radiation. During primary crystallization, both average long period and lamellar thickness exhibit a significant decrease. During secondary crystallization, the long period...
