The mechanisms of anti-icing properties degradation for slippery liquid-infused porous surfaces under shear stresses

The role of nanoparticle charge in crystallization kinetics and ice adhesion strength for dispersions of detonation nanodiamonds

“…The data shown in the figure correspond to the values obtained by averaging over 50 samples for each frozen liquid. It was shown earlier 43 that during the recalescent stage of liquid freezing, the metastable pure ice menisci grow inside the grooves of the surface texture due to local supersaturation of the water vapors. The ice, as formed in the grooves of the texture, is shown to be metastable and sublimates during further equilibration of the frozen liquid.…”

“…Thus, the ice adhesion strength demonstrates a gradual decrease in the time of ice exposure at a fixed negative temperature after water crystallization. 23,43 The data presented in Fig. 4c correspond to the equilibration time of 5 h for all types of freezing liquids.…”

Durable Icephobic Slippery Liquid-Infused Porous Surfaces (SLIPS) Using Flame- and Cold-Spraying

“…For the SLIPS samples after the cyclic icing-deicing test, the droplets were pinned with FS-PE SLIPS, and they were 18 • ± 2 • for FS-PEEK SLIPS with a hysteresis of 1.5, and 17 • ± 4 • for CS-PEEK SLIPS with a hysteresis of 6.3. After the cyclic icing-deicing test, the oil content in the surface roughness decreased [108], as can be seen from the images of SLIPS after the icing tests in Figure 10, due to the mechanical effect of the ice accretion and the centrifugal ice adhesion test. It is worth mentioning that only an amount of the surface oil layer may decrease; the SLIPS structures were successful in maintaining the oil, even after the cyclic icing-deicing test, as demonstrated in Figure 9, for the SLIPS FTIR spectra before and after icing compared to silicon oil and the porous coating spectra.…”
