Table 1 The optimal composition and resultant ice adhesion strength for 10 different icephobic polymer/plasticizer combinations fabricated in this work.

The amount of oil in each system was optimized for both low ice adhesion and good mechanical durability. For a complete list of surfaces, see table S2. PVC, polyvinyl chloride. *The φoilmax values for plasticized PVC and PS were found using a best fit to Eq. 9 and do not represent values obtained by swell tests.
