We report on the synthesis and surface characterization of thin-film nanocomposites using functionalized single-walled carbon nanotubes (CNTs) with a diamine-terminated oligomeric poly(ethylene glycol) [poly(ethylene glycol) bis (3-aminopropyl)-terminated 1500]. The functionalized CNT samples are soluble in highly polar solvents. Their common solubility allows for the intimate mixing of the functionalized nanotubes with the matrix polymer–poly(vinyl alcohol) by dip coating and wet casting to form nanocomposite thin films. We demonstrate the alignment of the CNT bundles in the thin films that are formed without the external field forces. We present our results and discuss alignment reorientations from the characterizations of the nanocomposite thin films by using a Raman spectrometer, scanning electron microscopy, and atomic force microscopy.

Coating Method

Thin films of poly vinyl alcohol (PVA) were prepared on pre-cleaned glass substrates by Dip Coating Method. FTIR spectrum was used to identify the functional groups present in the prepared films. The vibrational peaks observed at 1260 cm-1 and 851 cm-1 are assigned to C–C stretching and CH rocking of PVA.The characteristic band appearing at 1432 cm-1 is assigned to C–H bend of CH2 of PVA. The thickness of the prepared thin films were measured by using an electronic thickness measuring instrument (Tesatronic-TTD20) and cross checked by gravimetric method. XRD spectra indicated the amorphous nature of the films.Surface morphology of the coated films was studied by scanning electron microscope (SEM). The surface revealed no pits and pin holes on the surface. The observed surface morphology indicated that these films could be used as dielectric layer in organic thin film transistors and as drug delivery system for wound healing.
