Here, in Figure the domed disk detaches from the film with a force comparable to that of the unmodified PDMS if the measurement is made soon after the contact is made. Following detachment, the region of original contact remains smooth, i.e. no roughening of the PDMS coating is evident during short contact time. However, if the domed disk is detached after the joint is kept submerged in water for longer time, the detachment force decreases systematically. After 24 h, the domed disk detaches spontaneously from the hygro-elastomeric film without any measurable force. Microscopic observation reveals that fine morphological patterns starts developing on the H-PDMS film underneath the domed disk after it is immersed in water for a short duration.
