Abstract

In this study, the effects of drying temperature andPolyaniline| Nanostructured film| Temperature and pressure effects| Thermal properties| Mechanical pressure on the surface structure and dynamical properties of Polyaniline| Nanostructured film| Temperature and pressure effects| Thermal properties| Mechanical (PAni) were studied. PAni was synthesized through the aniline polymerization process in the presence of ammonium persulfate in acidic medium and normal methyl-2-pyrrolidine solution. The obtained solution was dipped on a substrate of quartz glass. Atomic force microscopy (AFM) analysis based on nano-indentation tests were used to determine the values of hardness, Young’ s modulus and Poisson’ s ratio of the films. The results of the analysis of the scanning electron microscope demonstrated that the surface morphology of the film is changed from a fiber-to-interconnected cross-linked networkby increasing the drying temperature. The transmission electron microscope analysis showed that the diameter of the fibers on the surfaces dried at 318 K and 418 K was 18 and 30 nm, respectively. AFM results showed that the mean surface roughness of PAni film at 318 K withoutPolyaniline| Nanostructured film| Temperature and pressure effects| Thermal properties| Mechanical pressure was 63 nm, while for the film pressed at 5 MPa was less than 35 nm. Thermo-mechanical analysis showed that the glass transition temperature of the PAni film prepared withoutPolyaniline| Nanostructured film| Temperature and pressure effects| Thermal properties| Mechanical pressure and the film pressed at 5 MPa were 386 K and 378 K, respectively.
