3.1. Endothermic peaks of polymer types
TGA-DSC curves were measured for all of the selected polymer types
to detect characteristic endothermic reactions. The solid-liquid phase
transition is an endothermic event and appears as endothermic (negative)
peak in DSC thermograms (Fig. 1). We hypothesized that the different
endothermic peaks of the polymers can, in principle, be used
for their identification in small microplastic debris in a single instrument
run. As can be seen from
