Double-layer core/shell-structured nanoparticles in polyarylene ether nitrile-based nanocomposites as flexible dielectric materials

Copper tetra-amine phthalocyanine (NH2-CuPc) was grafted onto barium titanate (BaTiO3) whose surface was modified by carboxyl-functionalized polyarylene ether nitrile (CPEN), (CPEN-f-BT@ CuPc), using rotary coating technology combined with an ultrasonic dispersion technology and a post-treatment bonding process. The CPEN-f-BT@ CuPc/polyarylene ether nitrile (PEN) nanocomposites show stable dielectric constant and energy density in the temperature range of 25-160 degrees C, which demonstrate huge potential for use as organic film capacitors.
