Droplet-bubble interactions have a significant impact on various applications, but understanding the mechanisms and laws behind these interactions is a challenge due to the complex flow states. This study investigates the wetting mechanism, shape diffusion laws, and controlled impact of droplets on patterned surfaces and showcases the potential application of multilayer soap bubbles as microreactors.
Droplet-bubble interactions have a significant impact on the efficiency and quality of work in hydrogen energy cells, drug development, microfluidic chips and wastewater treatment. However, due to the complexity of the flow state of droplet-bubble interactions, it's still a great challenge to reveal the mechanism of action and laws of the impact process. This work prepares patterned surfaces by laser etching and fluorosilane (FAS) , reveals the wetting mechanism and the shape diffusion laws of soap bubbles on patterned surfaces, obtains the flow map of droplet impacting single-layer soap bubbles, realizes the controlled impact of droplets on multilayer bubbles, and demonstrates the application potential of multilayer soap bubbles as microreactors. The results show that the increase of the volume of soap bubbles on the patterned surface to 1
