Abstract EN
The formation mechanism of space charges in polyimide (PI) which was exposed to dielectric barrier discharge (DBD) in SF6 medium and the effects of the space charges on interfacial and electrical properties of PI were investigated.
The variation of normalized surface charge density on PI sample was calculated and illustrated for different DBD exposure times.
The surface potential was measured to determine the effect of the space charges on the sample.
Then, the contact angle values were measured to obtain the relation between the surface energy and the surface charge density.
The expressions for the total charge and the concentration of trapped electrons were derived by using Poisson and continuity equations at stationary state.
The space charges were determined experimentally by using thermally stimulated depolarization current (TSDC) method.
Also, SEM image and FTIR spectrum of virgin and treated samples were presented to observe the structural variations.
It was seen that the approach for the formation mechanism of the space charges agreed with the experimental data.
However, it was concluded particularly for the short-time DBD treatments that the space charges accumulated in the sample should be considered besides the effects of surface functionalization in the determination of the surface energy.
