Synthesis, structure, and thermal stability of poly(methyl methacrylate)-co- poly(3-tri(methoxysilyil)propyl methacrylate)/ montmorillonite nanocomposites

The structure and the thermodegradation behavior of both poly(methyl methacrylate)-co-poly(3-tri(methoxysilyil)propyl methacrylate) polymer modified with silyl groups and of intercalated poly(methyl methacrylate)-co-poly(3- tri(methoxysilyil)propyl methacrylate)/Cloisite 15A™ nanocomposite have been in situ probed. The structural feature were comparatively studied by Fourier transform infrared spectroscopy (FTIR), 13C and 29Si nuclear magnetic resonance (NMR), and small angle X-ray scattering (SAXS) measurements. The intercalation of polymer in the interlayer galleries was evidenced by the increment of the basal distance from 31 to 45 Å. The variation of this interlayer distance as function of temperature was followed by in situ SAXS. Pristine polymer decomposition pathway depends on the atmosphere, presenting two steps under air and three under N2. The nanocomposites are more stable than polymer, and this thermal improvement is proportional to the clay loading. The experimental results indicate that clay nanoparticles play several different roles in polymer stabilization, among them, diffusion barrier, charring, and suppression of degradation steps by chemical reactions between polymer and clay. Charring is atmosphere dependent, occurring more pronounced under air. © 2012 Society of Plastics Engineers.

Reflexão sobre pesquisa colaborativa: articulações escola e universidade (Ciência do Sistema Terra, Currículo e Formação de Professores)

This work was born from public presentation done during 8th Meeting in High Level Education Program at University Moura Lacerda, Ribeirão Preto, SP, Brazil, in October 2012. That time showed up theoretical hypothesis of teacher education done by a collaborative research group of teachers and researchers and main results for Pedagogy course and students of basic levels. This paper intends to show up the findings of researches done by group of studies for Earth System Science and teacher education. The aim is to think about curriculum politics and teacher education from teachers’ practices, researches and studies on high school level. Moreover, we show up theoretical fundamentals which guide our actions and think. After we treat of organization, results and curricular innovations guided by Earth System Science and how that changes the view of nature of teachers and students. Qualitative methods of research help to describe curricular processes collectively done together with teachers of public schools. Our findings show up that teacher education must be a long, collective and interactive process to prepare high level teachers and researchers for teaching and teacher education.
