Figure 7.
Condensation of water vapor on three different depleted liquid-infused surfaces, namely, flat Si-LIS with 50 cSt oil (LIS on the flat silicon surface), and two nanochannel depleted lubricant-infused surfaces (dep-nc-LIS with 500 cSt oil, and dep-nc-LIS with 50 cSt oil), showing: (a) variation of heat-transfer coefficient (HTC) for depleted samples and (b) water contact angle before condensation and after 4 h 15 min of condensation on the depleted sample.
