Abstract: With abundant hydroxyl groups on the surface, nanosilica (nanoSiO2) was easy to react with organic polymers containing functional groups. It could improve the compatibility with polypropylene (PP) matrix and make nanoSiO2 dispersed more uniformly. Recent advances in PP/nanoSiO2 composites were introduced. The modified methods including surface treatment of nanoSiO2 particles and adding compatibilizer were reviewed. The impact of nanoSiO2 particle structure on the permeability, flame retardancy, electrical conductivity of matrix polymer was also discussed.
