عنوان انگلیسی Physical Study of PVA Filled with Carbon Nanotube and Nano Carbon with Roughness Morphology
چکیده انگلیسی مقاله In the present work nanocomposite thin films have been prepared from poly(vinyl alcohol) (PVA) mixed with carbon nanotube (CNT) and carbon nano particles (CN) by casted method. The aim of this work produce texture of PVA with CNT and CN, the effect of CNT and CN content in thin films nanocomposite were measured by utilizing reflectance and absorbance data. The contents of CNT and CN reinforcement in the PVA matrix increase the optical properties such as reflectance, absorption coefficient, refractive index, extinction factor. But the transmittance and reflectance of thin films nanocomposite (PVA-0.05CNT, PVA-0.05CN, and PVA-0.025CNT-0.025CN) decreased, on anther hand the conductivity and dielectric constant were increased. The direct allowed transition of energy gap decreased from 4.0 eV to 2.9 eV, the indirect allowed transition of energy gap decreased from 4.4 eV to 2.8 eV, respectively. Urbach energy was increased from 1.238 eV to 2.711 eV after added the CNT and CN to PVA texture. The scanning electron microscope was used to evaluate the particle sizes of CNT and CN after preparation from the experimental method, which used in the PVA lattice to constitute the thin films nanocomposite (PVA-0.05CNT, PVA-0.05CN, and PVA-0.025CNT-0.025CN). The AFM test used to exhibit the roughness.
