abstract = {Adhesion between a glass ball and a polydimethylsiloxane
(PDMS) sample is dependent on the PDMS cross-link density,
and the transformation of the material from the
uncrosslinked liquid state to the fully crosslinked solid
state is investigated in this study. The physical picture
reflected a gradual transition from capillary forces driven
contact mechanics to the classical
Johnson–Kendall–Roberts (JKR)-type contact mechanics.
PDMS was produced by mixing the base fluid and a
cross-linker at a ratio of 10 : 1 and allowed to slowly
cross-link at room temperature with simultaneous measurement
of the ball–PDMS interaction force. The PDMS sample was in
the liquid state during the first ≈16 hours, and in this
case the ball–PDMS interaction was purely adhesive, i.e.,
no repulsive interaction was observed. Later at the PDMS
gel-point the cross-linked PDMS clusters percolate,
converting the fluid into a soft (fluid-filled) poroelastic
solid. In the transition period, PDMS appears similar to
pressure-sensitive adhesives. There we observe so-called
“stringing” and permanent deformation of the material
impacted by the ball. At room temperature, it takes more
than ∼100 hours for PDMS to fully cross-link that can be
confirmed by the comparison with the earlier-studied
reference PDMS produced at elevated temperatures.},
