Abstract

PU/OMMT (Polyurethane/Organically Modified Montmorillonite) nanocomposites were prepared by in situ polymerization Technique. The structure of prepared nanocomposites and dispersion state of filler was studied and characterized by XRD and TEM. An intercalation type of morphology was observed by TEM. The mechanical properties of these nanocomposites at different loading levels of OMMT were also investigated using the Universal testing machine. The tensile strength, elongation at break and hardness shore were enhanced with the increase in the loading level of OMMT as compared to pure polyurethane. The obtained properties may be used in MEMS applications like pressure diaphragm, where the mechanical properties on nanoscale are crucial..
