In comparison with PP, the impact strength of PP/CaCO3 nanocomposites increased by about 65% and the hardness increased by about 5%. The nanocomposite hence can have a combination or have markedly different mechanical, electrochemical, electrical, catalytic, thermal and optical properties from the component materials [1, 4-7]. A series of MD simulations were carried out to determine the ISS of the nanoscale RVE reinforced with an individual CNT. The obtained results demonstrated that elongation strain and tensile strength of the natural rubber increased by adding nanofillers up to 10 phr (per hundred of rubber). They are all artistically enhanced with visually stunning color, shadow and lighting effects.
