Raman spectra, thermal and mechanical properties of poly(ethylene terephthalate) carbon-based nanocomposite films

Poly(ethylene terephthalate) (PET) nanocomposite film with 1wt% of nanodiamond terminated with carboxylic groups (PET- NDCOOH), PET nanocomposite film containing 1 wt% of NDCOOH and 0.3 wt % nanographene platelets (PET- NDCOOH-NGP) and a neat PET film have been prepared by melt extrusion. A Raman spectroscopic study was performed in order to establish the interactions between nanofiller (NDCOOH and NGP) and polymer matrix. The thermal behaviour of the PET nanocomposites was studied using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Mechanical properties were determined by tensile tests performed on strips that were cut from the prepared films in parallel and perpendicular directions with respect to the direction of film preparation. Raman and DSC results showed thar the incorporation of NDCOOH and NGP into the composite results in the enhancement of the crystallinity inducing the growth of crystalls in the polymer matrix. According to TGA results, the addition of NDCOOH and NGP enhanced thermal stability. The results obtained from the tensile strenght tests in the longitudinal direction showed that the incorporation of NDCOOH particles resulted in matrix plasticization. The increase in stiffness in the transversal direction can be ascribed to interactions between NDCOOH and PET matrix. The tensile strenght of PET-NDCOOH-NGP nanocomposite film in both directions decreased in comparison to neat PET.
