Designer petals shape ZnO nanoparticles as nucleating agents: Verification the mechanism of cavity nucleation in the polymer for foaming

The morphology, size and surface roughness of the nucleating agent significantly affect the nucleation effect for foaming in the polymer. In this work, four nucleating agents with different morphologies, namely DE, MS, OMMT and β- CD as heterogeneous nucleation agents were selected for a polypropyle...
