Before and after neutron irradiation, in order to identify the “adhesion” in silica nanoparticles, analyses have been conducted on transmission electron microscope (TEM) at small nano dimensions. Simultaneously, at relatively larger nano dimensions, the surfaces of the samples were observed by the scanning electron microscope (SEM). Moreover, analyses of the samples with SAED (selected area electron diffraction) technology on TEM device used for determining the structure of the nanomaterial. From TEM analyses, it has been found that little “adhesion” is observed at small dimensions (maximum 70 nm) under the influence of neutron irradiation and this “adhesion” directly influences the electrophysical properties of nanomaterials.
