"The aim of the project is the synthesis of nanocomposites with chemically bifunctional butylstannoxane nanoparticles (2 nm). The applicant\u2019s recent experience with this novel nanofiller indicates, that besides mechanical reinforcement, a strong improvement of oxidation stability can be expected in comparison to neat matrix. Planned is the synthesis of already described stannoxanes and of new derivatives with new functional groups and their incorporation into epoxies, polyurethanes and acrylic polymers. The stannoxanes will be characterized via 119Sn- and 1H-NMR, and the nanocomposites via dynamic mechanical thermal analysis and their morphology through electron microscopy and X-ray diffraction. An important goal is the understanding of the effect of this novel filler on mechanical properties and the study of the interesting phase behavior of the stannoxane clusters at elevated temperatures and the comparison with previously studied siloxane nanoparticles (POSS). A second goal is the study and optimalization of the stannoxanes\u2019 chemical stabilizing effect in nanocomposites."@en .
