large-scale generation of patterned bubble arrays on printed bi-functional boiling surfaces  -  heat transfer printing film
The nuclear control, growth and detachment dynamics of bubbles are of great significance for understanding boiling phenomenon and improving the heat transfer performance of nuclear boiling.
We reported a novel.
A functionally heterogeneous surface structure capable of regulating bubble-like nuclei, growth, and detachment dynamics.
In order to make the surface, first print the hydrophobic polymer lattice column on the substrate, and then deposit the hydrophilic nano-structure through the micro-reactor
Auxiliary nano-material deposition (MAND)processing.
The wet contrast between the hydrophobic polymer lattice column and the aqueous solution allows the preparation of heterogeneous surfaces with different wet regions.
Heterogeneous surfaces with various structures are manufactured and their bubble dynamics are studied under high heat flow, revealing various nuclear boiling phenomena.
In particular, for the first time, alignment and patterned bubbles with adjustable starting frequency and diameter were shown in boiling experiments.
A heterogeneous surface of 6 inch wafer size was prepared using our manufacturing method.
Pool boiling experiments were also performed to demonstrate the use of bi-at the same surface over Heat-
Compared to the bare stainless steel surface, the functional surface.
