Correlations Between Structures of Expanded Graphite – Polymer Composites and Acoustic Emission Phenomena / Korelacje Pomiędzy Strukturą Kompozytów Grafit Ekspandowany-Polimer A Zjawiskami Emisji Akustycznej

Abstract

Compressed expanded graphite was applied as a base matrix to the preparation of microporous composites as products of impregnation, polymerization and carbonization of poly-furfuryl alcohol. During carbonization, the original polymeric structure is transformed into an amorphous turbostratic carbon structure with ultramicropores. The structure, porosity and many chemical and physical properties change after each stage of their technological treatment.
