In this paper, a new method is proposed for the production of MWCNTs/PVC (multi-walled carbon nanotubes/ polyvinyl chloride) nanocomposites. In this method, a spray is used to produce layers of carbon nanotubes within a PVC matrix. Various parameters influence the production of the nanocomposite and its mechanical properties. These parameters are studied separately and the effect of each of parameter is calculated. All of the results of the statistical methods are obtained from experimental tensile testing. Results indicated that the most important parameter associated with constituents is the weight percent of carbon nanotube while the most important parameter associated with production is the mold surface temperature. The interaction effect of the two ultimately effective parameters on each other is also analyzed, and the relevant diagrams of the Young modulus and the ultimate tensile strength are prepared as well. Values of the Young modulus and the ultimate tensile strength are obtained for different weight percent values of the carbon nanotube.
