The surfaces prepared under this category show a well-strung morphology unlike the sintered-morphology seen with SP-1–SP-4. Therefore, the authors postulate that the CHF enhancement is dependent on the dynamic contact angles which dictate the wettability on the surface. The surfaces here exhibit high CHFs which is attributed to the change in the advancing contact angles influenced by the roughness on the surface. Hierarchical microstructures are shown to manipulate the surface forces holding the contact line due to its large effective contact line length on these surfaces [38]. The arithmetic mean roughness, *R*_{a}, values for CA-1, CA-2, and CA-3 were 13.7 *μ*m, 8.93 *μ*m, and 12.33 *μ*m, respectively. The corresponding CHF values were 216 W/cm^{2}, 176 W/cm^{2}, and 188 W/cm^{2}, respectively. The plain chip had a *R*_{a} and CHF values of 1.1 *μ*m and 128 W/cm^{2}, respectively.
