Abstract:Polyamide, as a polar polymer, possesses a large intrinsic dipole moment and excellent mechanical properties, making it a highly promising dielectric material. Nevertheless, the dipoles in traditional polyamides are constrained by hydrogen bonding, resulting in a diminished capacity for dielectric polarization and significant dielectric losses. In this study, traditional diamine was replaced with piperazine to fabricate a hydrogen-bond-free polyamide by employing structural design, which alleviated the limitat… Show more
