Abstract

  We describe particle coating using ultrasonic irradiation in high-pressure carbon dioxide (CO₂). Host microparticles were coated with guest nanoparticles. Shock waves generated by collapsing cavitation bubbles induced with ultrasonic irradiation accelerated the deagglomeration and dispersion of guest nanoparticles, and achieved dry particle coating in liquid CO₂. Host microparticles coated with guest nanoparticles were observed using scanning electron microscopy (SEM). This revealed that the guest particles were completely coated with guest nanoparticles, and a smooth coating surface was obtained.<br>
