ABSTRACT
92This chapter reports the simple method for in situ synthesis of Fe2O3 and Al2O3 with poly methyl methacrylate (PMMA) and its characterization. The hematite (Fe2O3) and aluminum oxide (Al2O3) nanoparticles were prepared by ultrasonication method using iron III nitrate and sodium hydroxide as precursors and for alumina the synthesized aluminum nanoparticles from aluminum isopropoxide and lithium aluminum hydride were exposed to open air to undergo oxidation and to form aluminum oxide or alumina. By using methyl methacrylate (MMA) as a monomer and sodium dodecyl sulfate (SDS) as a surfactant a combined ultrasound effect and proper initiation of potassium persulfate (KPS) initiator the PMMA is synthesized by emulsion polymerization technique. The conversion of MMA to PMMA is approximately 90%. The average size of the PMMA is of 3 nm, Fe2O3 loaded PMMA is around 1 nm and Al2O3 loaded PMMA is around 6 nm. The novelty of the work is seen in obtaining nanosize range (less than 10 nm) of the particles by sonicating it for 45 min.
