Abstract

HYDROPHILIC SULFONATED MONOMERS WERE GRAFTED ONTO THE BROMINATED SILICA NANOPARTICLE (BSN) VIA ATOM TRANSFER RADICAL POLYMERIZATION (ATRP) OF 0.8 AND 2.0 M 2-ACRYLAMIDO-2-METHYL-1-PROPANE SULFONIC ACID (PAMPS-G-SN) AND 1.2 M STYRENE SULFONIC ACID SODIUM SALT (PSSA-G-SN) AT 25 OC FOR 24 H. BSN AND COPPER (II) BROMIDE/BIPYRIDINE (BPY) WERE USED AS THE INITIATOR AND CATALYST/LIGAND RESPECTIVELY. MOLAR RATIO OF THE MONOMER: INITIATOR: CATALYST: LIGAND WAS SELECTED FOR ALL REACTIONS TO BE 45: 1: 1: 2. BSN WAS SYNTHESIZED BY COVALENTLY ATTACHING OF THE 2-BROMOPROPIONYL BROMIDE (BPB) ONTO THE SURFACE OF AMINOPROPYL-FUNCTIONALIZED SILICA NANOPARTICLES (ASN) WHERE ASN WAS SYNTHESIZED VIA REACTION BETWEEN THE 3-AMINOPROPYLTRIETHOXYSILANE (APTES) AND SILICA NANOPARTICLES (SN). ASN, BSN, PAMPS-G-SN AND PSSA-G-SN WERE CHARACTERIZED BY FT-IR AND TGA ANALYSES. IT WAS FOUND FROM FT-IR AND TGA RESULTS THAT BOTH HYDROPHILIC MONOMERS WERE SUCCESSFULLY GRAFTED ONTO THE BSN. GRAFTING AMOUNTS OF THE SULFONATED POLYMERS ONTO THE SN WERE ESTIMATED FROM TGA CURVES TO BE 32% AND 49% FOR PAMPS AND 30% FOR PSSA.
