Synthesis, structural characterization, and thermalproperties of the poly (methylmethacrylate) / 𝛿 FeOOH hybrid material: an experimental and theoretical study. Journal of Nanomaterials, v. 2016, p. 1-7, 2016. Disponível em: <http://www.hindawi.com/journals/jnm/2016/2462135/>. Acesso em: 16 jun. 2016.1687-4129http://www.repositorio.ufop.br/handle/123456789/6677The 𝛿-FeOOH/PMMA nanocomposites with 0.5 and 2.5 wt.% of 𝛿-FeOOH were prepared by grafting 3 (trimethoxysilyl)propyl methacrylate on the surface of the iron oxyhydroxide particles.TheFTIR spectra of the 𝛿-FeOOH/PMMA nanocomposites showed that the silanemonomers were covalently attached to the 𝛿 FeOOHparticles. Because of the strong interaction between the PMMA and 𝛿-FeOOH nanoparticles, the thermal stability of the 𝛿-FeOOH/PMMA nanocomposites was improved compared to the pure PMMA.The SEM analysis conferred the size agglomerate of particles regarding the morphology of samples.The theoretical study enabled a better understanding of the interaction of the polymer with the iron oxyhydroxide.The DFT-based calculations reinforce the radical trapping mechanism of stabilization of nanocomposites; that is, Fe3+ species might be able to accept electrons coming from the organic phase that decomposes via radical unzipping.The radical scavenge effect delays the weight loss of polymer.en-USabertoArtigo publicado em periodicoThis is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.
