A simple method for fabrication of filler-free stretchable polydimethylsiloxane surfaces

► Changes in surface composition of polydimethylsiloxane surfaces were studied after argon plasma exposition. ► Aging processes were studied in different atmospheric conditions. ► Free radicals are created and the nature of these radicals has been highlight. ► Silyl radicals react with allyl groups of antagonist filler-free polydimethylsiloxane resin during the crosslinking step. ► A high interfacial resistance has been observed under elongation/retraction cycles.
