Abstract

Thermally Stimulated Current (TSC) spectroscopy and Differential Scanning calorimetry (DSC) have been applied to the characterization of the microstructure of Poly (Ether Ether Ketone)/PEEK. the dielectric relaxation spectra show two modes, dependent upon crystallinity:

  • * for the mode stuated in the vicinity of the glass transition temperature, two components have been distinguished and attributed to the molecular mobility in the ‘true amorphous phase’ and in the ‘rigid amorphous region’.

  • * below 0°C, two sub-modes appear, situated around-110°C and-75°C, due to the two different crystal entities, beads and laths.

Zusammenfassung

Zur Beschreibung der Mikrostruktur von Poly(Ether-Ether-Keton)/PEEK wurden TSC und DSC angewendet. In Abhängigkeit von der Kristallinität zeigen die Dipolrelaxationsspektren zwei Arten:

  • * in der Nähe der Glasumwandlungstemperatur konnten zwei Komponenten unterschieden und der Molekülbeweglichkeit in der ‘echten amorphen Phase’ und in der ‘starren amorphen Region’ zugeordnet werden.

  • * unter 0°C erscheinen wegen der zwei Kristallgebilde Perlen und Zäpfchen bei-110° und-75°C zwei Unterarten
