Organic pending groups- Strongly hydophobic
Order of increasing surface energy for single carbon based moieties is*:
CF3- - CF2 - -CH3- - CH2-
This explains why PDMS is less surface active than alkanes
* Ref: W.A. Zisma StudiesAdvances in Chemistry Series, No.43 American Chemical Society: Washington DC, 1964, p1
Silicones have low Surface Tensionalso:
PDMS S.T. for wetting = 24mN/mPDMS Liquid S.T. = 20 nM/m
Silicones spread over its own adsorbed film- complete surface coverage- excellent spreading agent
