Abstract

In this study, the nanocomposite thin films were prepared from polyvinyl alcohol (PVA) that reinforced with different proportions of carbon nanotubes (CNTs) via hand casting method . The current work aims to create the connection between improving surface characteristics for high efficiency electronic covering and biodegradability. The nature of bonding between the PVA and CNTs were studied by Fourier-transform infrared spectroscopy (FTIR). Wettability properties were studied via contact angle analyzer. The two dimensions' morphology of nanocomposites was studied using atomic force microscopy (AFM). Biodegradable tests of nanocomposites were performed via burial in soil for seven days. According to the contact angle data, adding PVA to CNTs causes the contact angle decreased from 95 degrees to 56 degrees at a concentration of 0.001 wt% of CNTs, and it then increases to 78 degrees at a concentration of 0.03 wt% of CNTs. The results of the infrared analysis showed that the physical interaction between the carbon nano tubes and the poly vinyl alcohol matrix, as well as, the IR intensity transmittance decreases with the addition of carbon nano tubes. Atomic force microscopy results prove that the roughness average decreases with increasing the CNTs ratios from 0.01 up to 0.03 wt% percent, bearing index increases with increasing the carbon nano tubes concentrations, and surface flatness increases with increasing the carbon nano tubes ratios. The best sample for this study was TH2 (0.002 wt of CNTs.
