This study explains the play of void or the inclusion of various mechanical properties and especially, the sturdiness of different polymers are explained. Impact of interphase around the voids turns out to be more essential and trademark changes in the distortion methodology of nano and micro particles. Minimizing the size of void and distance between the intervoid are the major concern. These techniques are uncovered by many different methods such as modified rubber polymer, nano fiber and nanocomposites. Few nanoscopic toughness methodologies are explained in detail. This study concluded with because of the advantages, nanovoids are selected over microvoids.
