T. Steckenreiter et al., SOLVENT-INDUCED SENSITIZATION OF ION TRACKS IN PET ANALYZED BY SMALL-ANGLE X-RAY-SCATTERING AND DIFFERENTIAL SCANNING CALORIMETRY, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 105(1-4), 1995, pp. 200-203
The influence of the organic solvent N,N,-dimethylformamide (DMF) on i
on tracks in polyethyleneterephthalate (PET) was investigated by small
-angle X-ray scattering (SAXS) and by differential scanning calorimetr
y (DSC). The experiments were performed on non-irradiated, irradiated
and DMF-treated samples. After ion irradiation the SAXS pattern change
d considerably. From the comparison of the SAXS pattern of the irradia
ted samples before and after DMF sensitization, it can be concluded th
at DMF induces a process restoring the lamellar structure. With DSC we
determined the melting enthalpy. Compared with non-irradiated PET the
melting enthalpy of irradiated samples decrease. By DMF-sensitization
this decrease of melting enthalpy is enhanced.
