Preparation,Mechanical and Electrical Properties and Water Absorption Study of Novel Bisphenol-C-Formaldehyde-Acrylate Treated and Untreated Jute Composites

The depolarization current spectra for polyvinyledenefluoride (PVDF), poly methylmethacrylate (PMMA), and their double-layered samples have been recorded under different polarizing conditions. When double-layered sample is polarized at 323 K with high field, a new TSDC peak is observed that is inherent in PMMA and PVDF when considered individually. This is because of the trapping charge carriers at the PVDF–PMMA interface. The space charge peak is shifted toward the lower temperature side for the PMMA and PVDF samples; however, this trend of peak shifting was not found for double-layered samples. The trapping of charge carriers in the metal polymer interface is responsible for space charge peak. This trapping of charge carriers in polymer-polymer interface is interesting, and this process is responsible for interfacial polarization in double-layered samples.
