Effect of Nanoparticle Mobility on Toughness of Polymer Nanocomposites

Nanoparticle orientation and alignment under tensile stress results in enhanced toughness in nanocomposite materials. This energy‐dissipation mechanism, which is not observed in conventional polymer composites, is applicable to both semicrystalline and amorphous polymer‐composite systems. The mechan...

Summary:Nanoparticle orientation and alignment under tensile stress results in enhanced toughness in nanocomposite materials. This energy‐dissipation mechanism, which is not observed in conventional polymer composites, is applicable to both semicrystalline and amorphous polymer‐composite systems. The mechanism depends on the mobility of the nanoparticles in the matrix, as shown in the Figure before (left) and after (right) stretching.
