Abstract:When the polymer nanocomposites fill with carbon nanotubes, it exhibits high electrical conductivity and improved mechanical properties even at low concentrations. However, carbon nanotubes which are used as a filler does not have a chemically active surface. Therefore, they cause heterogeneous distribution and insufficient interface interaction formation inside the polymer matrix. This induces a decrease in polymer nanocomposites' electrical anad mechanical properties. Activation of carbon nanotubes in the preparation stage of nanocomposites help to improve the structural characteristics. It also plays an important role in the development of the properties of composites by providing homogeneous dispersion of carbon nanotubes in the polymer matrix. The use of carbon nanotubes in polymer nanocomposites allow them to use as high performance materials because of their properties. These materials have different mechanical properties when compared to other conventional engineering materials (metals, ceramics and plastics). In this study unlike the other studies in the literature, multi-walled carbon nanotubes (MWCNT) containing nanocomposites produces with high mechanical and electrical properties and changes in electrical resistance and also thermal analysis were investigated. For the characterization of the prepared Nano composite, contact angle measurements (DSA), the surface energy calculations, morphological features, FTIR and ATR spectroscopy, atomic force microscopy (AFM), mechanical strength tests, thermal gravimetric analysis (TGA), dynamic mechanical analysis and electrical conductivity measurements were made.
