Evaluation of filler particle size within polymer matrix by optical spectroscopy

Evaluation of filler particle size within polymer matrix by optical spectroscopy Polymer composites with inorganic fillers of different nature, concentration, particle size and shape were studied by optical spectroscopy (UV, visible, and IR ranges), optical and electron microscopy, and dynamic light scattering. An experiment to determine the size of the filler particles in aqueous suspension in the polymer matrix of a composite and directly in powders was conducted.

Abstract

Polymer composites with inorganic fillers of different nature, concentration, particle size and shape were studied by optical spectroscopy (UV, visible, and IR ranges), optical and electron microscopy, and dynamic light scattering. An experiment to determine the size of the filler particles in aqueous suspension in the polymer matrix of a composite and directly in powders was conducted. It was shown that with increasing concentration aggregation of particles on drying an aqueous slurry occurs to a greater extent than for the filler in the polymer composite. It was demonstrated by examples that the optical spectroscopy can be successfully used for the analysis of sub-micron and micron sized filler particles in a polymer matrix or suspension.
