Abstract

This paper examines the results of the characterization of two functional composites: Poly(methyl methacrylate)(PMMA)-Ce:YAG (yttrium aluminium garnet doped with cerium) and PMMA-cobalt hexacyanoferrate (CoHCF). Thecomposites were prepared as possible emitters in the fields of lighting thermal sensors. The prepared composites were characterizedusing transmission electron microscopy (TEM), nuclear magnetic resonance (NMR) spectroscopy, thermogravimetricanalysis (TGA), differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA) analyses to studythe correlation between micro and macro characteristics. We found that the molecular interactions of the two differentfillers with the matrix were localized in different sites of the polymer chains. Moreover, the composites showed anincreased thermal strength and stiffness, in particular the PMMA-Ce:YAG composite.
