Özet

One of the most studied biocomponents is cellulose and its derivatives. Chemical structures of the nanocomposite films were investigated by Fourier Transform Infrared Spectroscopy (FT-IR) and X-Ray Diffraction (XRD) analyses. In the Scanning Electron Microscope (SEM) images taken at 5000 x magnification, the films with the best dispersion of nano-reinforcements; are amine modified nano SiO2 doped 2-hydroxyethyl cellulose (2-HEC) and hydroxypropyl cellulose (HPC) films. SiO2 dispersion has not been homogeneous in neutral nano SiO2 doped HPC and hydroxypropyl methylcellulose (HPMC) films. On the other hand, in the amine modified nano SiO2 doped HPMC film, micron-size agglomerations were observed on the film surface. When the thermal resistance of the films was examined, it was determined that the amine modified nano SiO2 doped HPMC film was the highest at 344 ?. When stress-strain values were compared, amine modified nano SiO2 doped HPMC film was the best film sample with a strain value of 101.7 %.
