Abstract

Silane encapsulated magnetic iron oxide nanoparticles were synthesized through a sequential approach. The nanoparticles were synthesised via a coprecipitation method to form Fe₃O₄ particles with an average particle size of 8.3 ± 2.3nm. Iron oxide nanoparticles were then coated with 3-glycidoxypropyltrimethoxysilane (GPTMS) to form core-shell type particles. Coating was performed using a base catalysed sol-gel process involving the direct condensation of GPTMS onto the particle surface. Elemental composition and crystal structure of the uncoated nanoparticles were determined by XRD. The coated particles were characterised with infra-red spectroscopy and energy dispersive x-ray spectroscopy (EDX) to confirm the presence of silane on the particles. TEM analysis and Scherrer broadening analysis of XRD were used to determine particle size and morphology of both coated and uncoated particles.
