摘要

Titania-containing Polyarylene ether nitriles (PEN) hybrid films have been successfully fabricated via in-situ sol-gel process, nanosized TiO₂ particles are found well dispersed within the polymer matrix. The dielectric properties of the films were measured to find that dielectric constant as well as dielectric loss of the hybrid films increased linearly with the increasing TiO₂ content without sacrificing dielectric breakdown strength compared to that of the pristine polymer. Increased gel temperature reduced dielectric loss efficiently but has little influence on dielectric constant.
