Protonation of polyaniline with lightly sulfonated polystyrene
Protonation of polyaniline base with lightly sulfonated polystyrene in polar solvents such its dimethyl sulfoxide and N-methyl-2-py~olidone was investigated by UV-Vis absorption spectra. As the molar ratio of sulfonated polystyrenelpolyaniline increases, the conversion from polyaniline base form to salt form is observed owing 10 incrensed protonation. The isosbestic point clearly shows that qui...
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 کاملPreparation of Sulfur Mortar from Modified Sulfur
Mixtures of mineral aggregate and modified sulfur, wherein the modified sulfur functions as a binder, are termed sulfur concretes or sulfur mortars depending on the form of the mineral aggregate. Molten sulfur reacted with olefinic additive, at 130-140 ºC, and then mixed with preheated filler and aggregates. Sulfur mortar samples were prepared by mixing 32 % molten sulfur, 10 % filler and 5...
متن کاملAssembly of 1D Granular Structures from Sulfonated Polystyrene Microparticles
Being able to systematically modify the electric properties of nano- and microparticles opens up new possibilities for the bottom-up fabrication of advanced materials such as the fabrication of one-dimensional (1D) colloidal and granular materials. Fabricating 1D structures from individual particles offers plenty of applications ranging from electronic sensors and photovoltaics to artificial fl...
متن کاملPhase Behavior of Sulfonated Polystyrene Systems
INTRODUCTION Polymer blends are of great interest because they provide an economical route to design and produce novel materials that meet the challenging requirements for industrial applications. Recently, a variety of experimental and theoretical work has been conducted as a means for producing materials with improved properties compared to those of its constituents. Some of the findings sugg...
