ABSTRACT = {In this work, neutron induced structural modifications, on the biaxially-oriented polyethylene
naphthalate (BOPEN) film, were studied by X-ray diffraction technique (XRD), Fourier transform
infrared spectroscopy (FTIR/ATR), scanning electron microscopy (SEM) and polarized light
optical microscopy (PLOM). The irradiation with neutron was carried out, under air, at room
temperature. The changes of the structure, in volume and in surface were evaluated under the
impact of neutron’s flux composed by thermally neutrons and fast neutrons. The X-ray technique
showed the effect of the neutron flux’s fluence on the crystallinity of the BOPEN, which was also
determined through the FTIR/ATR spectroscopy, traduced by the absence and (or) presence of
the absorption bands characteristics of crystalline and amorphous phases. The SEM and PLOM
characterizations, revealed a radical change in the texture of the surface which passes from an
orderly homogeneous state, observed on the NIR-BOPEN film, to a degraded state, shown up
in irradiated samples (IR-BOPEN) case.},
