Morphological study and thermal analysis of surface modified {alpha}-FeOOH via in situ polymerization of methyl methacrylate
Considering the interfacial characteristics of goethite ({alpha}-FeOOH, iron oxide yellow), the in situ polymerization of methyl methacrylate was employed to modify the surfaces of {alpha}-FeOOH pigments in aqueous slurry. The scanning electron micrographs indicated that the poly(methyl methacrylate) anchored on the surfaces of the particle homogeneously. From this study, it was found that one of the key requirements in the synthesis of the {alpha}-FeOOH-PMMA composite was to enhance interfacial compatibility between inorganic particles and organic monomer. Moreover, polymer-treated {alpha}-FeOOH particles were easily dispersed in organic medium to form a stable colloid and the heat resistance of {alpha}-FeOOH particles was improved.
