Analytical Centrifugation of Nanocomposites

Polymer nanosolutions are organic inorganic hybrid materials where the inorganic filler has at least one dimension in the nanometer scale. By varying the materials used in the process can open a whole wealth of properties which are adaptable and amendable for a wide range of applications in coating industry. However, the multifunctional performance of the polymer nanosolutions usually depends on the homogeneous dispersion state itself. To analyzing the dispersion state of polymer nanosolutions, the new S.T.E.P technology via analytical centrifugation can provide a wealth of information on polymer nanosloution, including real-time dispersability and shelf life. In this dissertation, we aim to establish a complete dispersability evaluation method and system for polymer nanosolutions, realizing the nanoparticles behavior of dispersion, particles-particles interactions, and particles-polymer relationship to characterize the dispersability of polymer nanosolutions.
