  We report an experimental study of the drying-induced peeling of a bilayer,
consisting of an elastomeric disk coated with a suspension of nanoparticles. We
show that although capillary forces associated with the scale of the droplet
can not compete with the adhesion of the elastomer on a surface, nevertheless
large tensile stresses develop in the coating, which results in a moment
bending the bilayer. We attribute this stress to the nano-menisci in the pores
of the colloidal material and we propose a model that describes successfully
the early stage curvature of the bilayer. Thus, we show that the peeling can be
conveniently controlled by the particle size and the coating thickness.
