MICROSTRUCTURAL ANALYSIS OF MULTI-SCALE POLYMER COMPOSITES USING OPTICAL MICROSCOPY AND ENTROPIC MEASURES

摘要

Entropic measures for the characterization of mixing have been used to quantify the concentration and dispersion of additives in a polymer matrix, but have not yet been applied to the dispersion and breakup of ideally discrete structures. This paper introduces measures and considerations to analyze optical micrographs with entropic and statistical measures to quantify the quality mixing and attempt to quantify fiber attrition in polymer composites that contain both micro- and nano-scale additives.
