Nanocomposites mechanical behavior, factors affecting

All these aspects have been overviewed in the following sections, preceded by a summary of the main factors affecting the mechanical behavior of nanocomposites and some modeling approaches that have been proposed. 

Factors Affecting the Mechanical Behavior of Nanocomposites 1119 Fiber... 

The group of Gu Z. in the 2009, reported the behavior of styrene butadiene/ rubber/organo-bentonite nanocomposite prepared from latex dispersion, content was lower than 12 mass%. The results showed were that presence of organo-bentonite in the nanocoposite affects direct in the thermo stability, mechanical properties and swelling behavior, which was attribute to the good barrier properties of the dispersed nanoparticles. The dispersion is an important factor that can affect various properties such as thermal stability [81]. 

Thus, according to works reported in the literature about PHA/CNT nanocomposites, we can conclude that the introduction of CNT in the PHA matrix can change and improve the nanocomposite properties. Thermal behavior, electrical conductivity, mechanical properties, and mainly the crystallization of PHA were the most affected properties by the addition CNT. Obviously, the properties of PHA/ CNT depends on several factors, such as the characteristics of PHA matrix and CNT, amount of CNT in the nanocomposite, method for producing nanocomposite, and functionahzation of CNT. The choice and control of all these factors should be made through the choice of properties to be reached.
