Liquid crystalline polymers (LCP) are attractive candidates for use as barrier films in packaging and high performance membrane applications due to their extraordinary barrier properties and chemical resistance. However, LCPs usually display extremely low viscosities, which makes processing them into multilayer films using coextrusion a challenge due to the mismatch of their viscosities with other...
In this study, we report layer thickness effect on the electrical insulation property of polysulfone (PSF)/poly(vinylidene fluoride) (PVDF) multilayer films having a fixed composition of PSF/PVDF = 30/70 (vol./vol.). Breakdown strength, dielectric lifetime, and electrical conductivity were studied for 32- and 256-layer films having various total film thicknesses. Among these films, those having thinner...
