RECOGNITION AND STATISTICAL SIZE DISTRIBUTION OF MICRODOMAINS IN TEM-IMAGES OF POLYIMIDE FILMS DURING THEIR PROCESSING

Sergei Bronnikov, Tatiana Sukhanova

Abstract

The surface morphology of polyamic acid films evolving under heating towards polyimide films is investigated with transmission electron microscopy. Micro-domains observed at the surface of the films are treated statistically and shown to form optimized statistical ensemble(s). The statistical size distribution of the micro-domains is described with the model of reversible aggregation. The distribution parameters, namely the aggregation energy and the mean diameter of micro-domains, are shown to depend on the chemical structure of the polymer and the heating temperature.
