Abstract

Nucleation in plasticized polymers as the first stage of temperature- or pressure-mediated synthesis of highly porous polymeric matrices is the key factor affecting the structural properties of synthesized matrices. Accordingly, quantification of growth/collapse processes in the ensembles of pore germs during their evolution is of importance for the characterization and control of the morphological and functional properties of matrices. Additionally, analysis of the growth/collapse kinetics for single pore germs allows for evaluation of the physical-chemical properties (the surface tension, the mass fraction of plasticizing agent in the polymer) depending on the external conditions. In this work, the robust image analysis procedures for quantitative description of the pore evolution on the base of video-reflectometry data are discussed. Experimental results obtained in the case of supercritical/subcritical foaming of polylactides are presented.
