title: Thickness and elastic modulus of plasma treated PDMS silica-like surface layer.
abstract: The adhesion of poly(dimethylsiloxane) (PDMS) rubber is largely improved by oxygen plasma surface treatment. The thickness of the silica-like surface layer is characterized by performing transmission electron microscopy imagery on microtome slices of welded plasma treated surfaces. The specific double layer contrast can be considered as equal to twice the thickness of the silica-like layer. The thickness measurements combined with strain-induced elastic buckling instability analysis gives an estimate of the elastic modulus of the silica-like layer equal to 1.5 GPa.
