Light and electron microscopy, electron beam damage and spectroscopy are used to study crystallographic morphology of spherulitic structures, nucleation and crystallization, stabilization, degredation, electrical conductivity, fluorescence, diffusion, permeability, solubility and mechanical properties of polymeric compounds.
Microstructure and diffusion in polymeric materials
Dr. D. Vesely
Mass transport of liquids in polymer matrixes is studied using FTIR microscopy, light microscopy, electron microscopy, fluorescence, MRI and gravimetry. New experimenta;l evidence shows discrepancy with the existing theories and a new theory had to be developed. This is based on molecular interactions and details of this mechanism are currently invesigated together with applications to miscibility, oxidative degradation, permeability and formation of new composite materials.
