Slow light ion irradiation of polymers II: etching of microbeam-irradiated Makrofol

Original language description

Thin polymer foils were irradiated by low energy light ions at various fluences and thereafter etched until electric currents could penetrate the foils. Both the etchant breakthrough times, and the times when the maximum recordable current signal is reached by the measuring equipment, are recorded as characteristic parameters to describe the etchant process in detail. At low to medium fluences, their correlations with the applied ion fluence reveal details of both underlying polymeric properties and radiative mechanisms, such as differences in the behavior of amorphous and crystalline regions and of the existence of crazes and cracks, as well as radiation-induced compaction of radiation damage via chain scission. At excessive fluences, polymers start favoring crack formation as a consequence of proceeding carbonization. There is both a gradual, smooth opening of conductive channels emerging across the foils, and a sudden, full current onset, indicating that a different mechanism is at work. The use of microbeams has the advantage not only of measuring (as usual) the overall average values of the relevant parameters of complex materials such as polymers but also allowing one to select specific very small areas from many possibilities to examine their peculiarities. However, this eventually results in completely different findings depending on the region examined. Based on a general understanding of the material's composition and behavior, the main task is now to find out which obtained result describes which individual composition, and how it all can find its place in a general overview. This is what we did here. There is huge variability in the intrinsic parameters during the etching of polymers irradiated with low energy light ions, such that the characteristic etching times reveal much larger scattering in the data compared to, e.g. the simple case of etched track formation by swift heavy ions. However, using a few proposed strategies, it is possible to derive valuable new information about the etching dynamics in different regions of the polymer.
