Controllable Static Breath-figure Processes to Form Ordered 3-d Microstructures on Polydimethylsiloxane Without Lithography and Molding

Year: 2022

Type: conference-paper

Abstract: We report a one-step lithography-free molding-free method to create highly-ordered hexagonally-packed 3-D micro-cavities on a soft polymeric material using a controllable static breath-figure formation process.To study the key control parameters that are missing in the existing literature for breath figure formation, we designed and built a system to monitor the real-time microscopic condensations at the under-curing polymeric interface with synchronous temperature measurement of water vapor and polymer interface altogether.Such a multimodal sensing system enabled us, for the first time, to visualize the entire breath figure formation process and correlate it to several key parameters to control the formation of breath figures.
