[ 1 ] - Nitroxide-Mediated Radical Polymerization of Styrene Initiated from the Surface of Titanium Oxide Nanoparticles

Titanium dioxide (TiO2) nanoparticles, with an average size of about 45 nm, were encapsulated by polystyrene using in situ nitroxide mediated radical polymerization   in the presence of 3-aminopropyl triethoxy silane (APTES) as a coupling agent and 2, 2, 6, 6-tetramethylpiperidinyl-1-oxy  as a initiator. First, the initiator for NMRP was covalently bonded onto the surface of Titanium dioxide na...

[ 2 ] - Surface-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 ...

[ 3 ] - Synthesis, characterization and swelling behavior investigation of gelatin-g-Poly(Acrylic Acid-co-Itaconic Acid)

A novel pH-responsive superabsorbent hydrogel based on gelatin was prepared through crosslinking copolymerization of poly (acrylic acid) and poly (itaconic acid). The copolymerization conditions including monomers, initiator, gelatin and crosslinker concentration, reaction temperature, and neutralization percent were systematically optimized to achieve a hydrogel with swelling capacity as high ...

[ 4 ] - سنتز نانو کامپوزیت پلی‌متیل استایرن/ نانوذرات اکسید روی (ZnO) به روش پلیمریزاسیون درجا (هم‌زمان)

در این کار، نانوکامپوزیت پلی متیل استایرن/ اکسید روی با استفاده از پلیمریزاسیون رادیکالی درجا سنتز گردید. نانو ذرات اکسید روی (ZnO) استفاده شده به روش رسوب‎گیری سنتز شد. ذرات به‌دست آمده با استفاده از روش پراش اشعه ایکس و میکروسکوپ الکترونی پویشی مورد شناسایی قرار گرفت. قطر اندازه ذرات برابر nm 23 می‌باشد. سپس سطح نانوذرات به‌وسیله جفت‌کننده سیلانی اصلاح گردید، تا پخش شدگی خوب و امتزاج‌پذیری خو...

[ 5 ] - Synthesis and Characterization of Polyaniline-Polystyrene-Chitosan/Zinc Oxide Hybrid Nanocomposite

A hybrid nanocomposite composed of polyaniline-polystyrene-chitosan/zinc oxide was prepared via a simple in situ polymerization method. The synthesized copolymers were analyzed using Fourier Transform InfraRed (FT-IR), and UltraViolet-Visible (UV–Vis) spectroscopies, ThermoGravimetric Analysis (TGA), and Field Emission Scanning Electron Microscopy (FE-SEM), X-ray diffracti...
