Mechanical proprieties of peelable coatings employed for cbrn decontamination

In this study, a PVA-based decontamination coating was subjected to mechanical investigations. The mathematical model employed for the numerical simulation of the polymeric coating behavior was chosen based on the results obtained by tensile and peeling experimental tests. According to research on four different types of polymeric coatings that differ based on the complexing agent, the chelator can affect both the mechanical properties and the decontamination factor. Given the experimental mechanical testing results, Ogden's law was shown to be the most appropriate technique to characterize the behavior of these viscoelastic peelable films. The results show that the numerical simulation accurately predicted the tensile and peeling test outcomes.
