Research Progress in High Dielectric Permittivity Polymeric Composites

The definition,characteristics,and polarization mechanism of dielectrics were first briefly introduced. The research and development of ferroelectric ceramics,metal and carbon filled polymers were reviewed. For the high dielectric permittivity polymeric composites used in embedded passive components and printed circuit boards,it was aimed to increase the dielectric permittivity and temperature resistance,decrease the dielectric loss,and stabilize dielectric permittivity and loss at wider ranges of temperature and frequency.
