To improve adhesion between polypropylene (PP) and mica in PP composites, acrylic acid (AA) is graft‐copolymerized onto PP by a melt‐mixing method. At the same time, applying a silane coupling agent to treat the surface of inorganic filler enhances the mechanical, thermal, and electrical properties, as well as decreases mold shrinkage and color difference of the composites.
