High pyroelectric effect in poly(vinylidene fluoride) composites cooperated with diamond nanoparticles

•Oxygen containing groups on the diamond nanoparticles increase the β-phased content in PVDF.•The thermal conductivities of diamond/PVDF films are enhanced due to the excellent thermal conductivity of diamond.•The enhanced β-phase content and thermal conductivity contribute to the increased pyroelec...
