Surface-modified Silicone Rubber
                                         poly(dimethylsiloxane) [PDMS]

Properties of the modified silicone surface:
  • reduced tack compared with untreated surfaces
  • smoother surfaces with reduced friction
  • hydrophilic i.e. water-wettable
    - concave menisci with water
    - contact angles drop from 105 to 30
    - surface free energy increases from 22 mN/m to approx. 56 mN/m
  • reduced electrostatic charging
    - surface resistivity drops from 1015 to 106 Ohm
  • altered permeability
    - increased permeability to polar compounds, e.g. water
    - decreased permeability to lipophilic (hydrophobic) compounds, e.g. oil

Tune these and other properties according your requirements.
