preparation of polystyrene nanocomposite by in situ atom transfer radical polymerization: study of polymerization kinetics in the presence of clay
styrene nanocomposites were synthesized by in-situ atom transfer radical polymerization at 110oc. the variations of monomer conversion and the linearity of semilogarithmic kinetic plot, some signs of living polymerizationand constant radical concentration in the reaction medium, were revealed by gas chromatography technique (gc). according to the gel permeation chromatography (gpc) results, the...
متن کاملModification of Polyvinyl Alcohol via Atom Transfer Radical Polymerization for Targeted Drug Delivery Applications
In current study,a hydrogel based on biocompatible polymerwas prepared. The functionalization of polyvinyl alcohol (PVA)with epichlorohydrin(ECH) to produce epichlorohydrin-g-polyvinyl alcohol (PVA/ECH) as a suitable macroinitiator for atom transfer radical polymerization (ATRP) reaction was investigated.ThenN-vinyl pyrrolidone (NVP) waspolymerized on the surface of macroinitiatorin presence of...
متن کاملSurface-initiated Atom Transfer Radical Polymerization and Solution Intercalation Methods for Preparation of Cellulose-G-PS-G-PAN/MMT Bionanocomposite
Cellulose was modified by polystyrene (PS) and polyacrylonitrile (PAN) via free radical and living radical polymerization, and then cellulose was used as the matrix in the preparation of polymer/clay nanocomposite, through a solution intercalation method. For this purpose, first, the graft polymerization of styrene (St) onto cellulose fibers was performed by using suspension polymerization and ...
متن کاملSpectral Radiative Properties of Three-dimensionally Ordered Macroporous Ceria Particles
Radiative properties of spherical heterogeneous particles consisting of threedimensionally ordered macroporous (3DOM) cerium dioxide (ceria) are numerically predicted in the spectral range 0.3–10μm. The particles are 1μm in diameter, with interconnected pores of diameter 330 nm and a face-centered cubic lattice arrangement. Predictions are obtained by solving macroscopic Maxwell’s equations usi...
متن کاملPreparation and self-assembly behavior of polystyrene-block-poly (dimethylaminoethyl methacrylate) amphiphilic block copolymer using atom transfer radical polymerization
Asymmetric and semi-symmetric amphiphilic diblock copolymers polystyrene-block-poly (dimethylaminoethyl methacrylate) (PS-b-PDMAEMA) with the same PS block length of 62 repeat units and quite short (3 repeat units) or equivalent (47 repeat units) length of PDMAEMA have been prepared simply by varying the ratio of the bromine-terminated macroinitiator polystyrene (PS-Br) to DMAEMA using atom tra...
