We fabricated REBCO supercondcuting films with nanoparticle APCs by using target exchange method and investigated their flux pinnig properties. The films with 5 vol% APCs showed high flux pinning properties than those with 10 vol% at 65 K and 77 K but, their pinning porperties were varied strongly depending on the number of pulses.
