The mechanical properties of the PVC/clay composites depended on the alkyl amin used for modification of clay. Among these clays, B166 exhibited the highest reinforcement effect of the PVC/dioctylphtalat (DOP) mixture. B166 improved mechanical properties of the PVC/DOP mixtures if clay content ≤ 2 %.wt. The FESEM images revealed nanoscale structure of the PVC/B166 composites, but some parts performed in microscale.

Because the covalent bondings between carbon atoms in graphene are very strong, mechanical properties of carbon nanotubes are very special. Young's modulus is defined as the ratio of the stress along an axis to the strain (ratio of deformation over initial length) along that axis in the range of stress in which Hooke's law holds.. An illustration of a carbon nanotube with 9 carbon-carbon parallel bondings.

In the case of ceramics, past studies on mechanical properties were mainly focused on the amorphous state of the precursor-derived ceramics. A substantial decrease in the contact stiffness would indicate fatigue failure of the nanocoating. FIGURE 2.55 Contact stiffness as a function of the number of cycles for a 20-nm thick carbon overcoat [174]. The hard- ness of the Ni–W alloy coatings was found to be in the range of 575–638 HV.
