Fig. 1. Mechanisms responsible for low ice adhesion.

(A) PDMS-based coatings having low or high ρ^CL, with or without interfacial slippage. (B) Relationship between ρ^CL and τ_ice for coatings without interfacial slippage. Error bars are 1 SD, and the best fit is found using the method proposed by York et al. (44). The slope is 0.51 ± 0.04. (C) Variation of τ_ice with ρ^CL for coatings with interfacial slippage. The best-fit slope is 1.01 ± 0.03. (D) Ice-reducing potential I* as a function of ρ^CL. Error bars are 1 SD, and for the best-fit curve shown, R² = 0.89.
