Positive Effect

To bring the positive effect of nanoscale calcium carbonate into play, macromolecular chains were introduced onto the particles by irradiation grafting polymerisation so that the hydrophobicity of the particles was increased and the loosen agglomerates became stronger. Tensile testing results demonstrated that polypropylene composites incorporated with the grafted nano-CaCO3 particles exhibited improved stiffness, strength and toughness at low filler content when proper grafting polymers are introduced. Species of grafting polymers adhered to the nanoparticles is an important factor affecting the modification effect of the matrix polymer. Therefore, composites performance can be purposely tailored accordingly.
