Abstract :
Samples of polyimide have been aged under a simulated space environment for periods of up to 48 months. Changes in the polymer have been monitored using TSDC measurements. The behaviour of activation energies derived from the TSDC spectra as a function of polarisation voltage and ageing conditions are discussed and a model to explain their behaviour is presented
