- Abstract
The chemical parameters of inorganic-organic building block surface-functionalization effect homogeneity and macroscopic properties of polymeric materials like mechanical characteristics. Therefore, a detailed study of the influence gives novel insights into the importance of surface-functionalization. Two types of nanoparticles, SiO2 and ZrO2, are synthesized in two different particle sizes, one in the lower nanometer length scale (5-10 nm in diameter) and one in the upper nanometer length scale (30-60 nm in diameter). The compounds prepared and surface-functionalized are incorporated in two different polymer matrices: epoxide resin and polymethylmethacrylate. Structural characterization of the resulting nanocomposites is performed by small angle X-ray scattering (SAXS): From the SAXS intensity, information on the size of nanoparticles and their agglomeration behaviour is obtained. This allows to characterize the influence of varying surface-functionalizations on the structural arrangement of nanoparticles in different polymer matrices.
