native PDMS least water contact angle

Hello there,

My group has fabricated a different ratio of PDMS structure(10:1 5;1
20:1). Without plasma treatment or chemical coating they are all
pretty hydrophobic.  The contact angle can be at least 90 degree.

Best,

Xiang

>I am observing the relationship between the native PDMS contact angle and the
mix ratio or curing time.

>Does anybody know the PDMS material least water contact angle? I mean the
native PDMS  no other chemical treatment. just change the mix ratio and curing
temperature.
