Morphology Matters: Irregular and Spherical Polymeric Powders in Anticorrosive Coatings

Polymeric particles are widely used owing to their tunable size and surface functionality; however, their intrinsically irregular morphology often degrades powder flowability, packing density, and compactibility, thereby limiting end-use performance.Herein, a rapid and efficient spheroidization strategy based on high-frequency electromagnetic heating (HFEH) is proposed to tailor the
