Key Points

Physical properties change due to oxidation in epoxy systems, impacting macromolecular mobility.
Key finding indicates crosslinking predominates in thermally oxidized epoxy diamine systems at 110°C.
Analysis used DMA in multi-frequency multi-temperature mode to evaluate ageing effects.
Supports the necessity to understand oxidation's implications on macromolecular mobility and material applications.

Implication

Thermal oxidation alters physical properties in epoxy systems, suggesting crosslinking plays a crucial role.

Abstract

Epoxy diamine systems were thermally oxidized at 110°C under air. Ageing was monitored using DMA in multi‐frequency multi‐temperature mode. The analysis led to the conclusion that the crosslinking predominates. Data were exploited using classical VTFH and WLF theories for estimating the changes of free volume‐related parameters with ageing.
