Characterising the dispersion of nano particles in a polymeric matrix - using different methods

摘要

Nanoparticles are of increasing interest to improve material properties. The most important impact factor augmenting the material is related to the degree of dispersion of the nanoparticles. A widely used method for characterisation is TEM, however only a small sample volume is accessible for evaluation, which in some cases hardly allows the determination of the "true" degree of dispersion. Utilizing methods which enable much better estimation of the degree of dispersion of nanoparticles, scattering techniques, in particular neutron scattering, are employed. A combination of conventional Small -
