Pdms contact angle
SpletIn the masked areas, the PDMS stays thus hydrophobic. This is confirmed by experiment: in the protected zone, the contact angle between water and PDMS is as high as the contact angle between water and non-plasmated PDMS (almost 100° in measure uncertainties). SpletThe initial contact angles θ of the coatings are all roughly around 100−110°, which is typical for PDMS. 46, 47 The amine polymers (Set 1) show low hydrophilicity with contact angles...
