About the Lab
Professor Byung-Mook Won's research lab specializes in the design and fabrication of advanced functional micro- and nanomaterials with exceptional mechanical and electrical properties. The lab focuses on developing highly stretchable polymer composites, such as PMMA/polypyrrole microtubes, for applications in flexible and wearable electronics. Key research directions include the creation of microarch structures via meniscus-guided assembly, enabling durable, high-performance sensors with real-time responsiveness under large deformations. The lab also investigates colloidal systems to understand fundamental behaviors in soft matter and self-assembly processes at the microscale.

2Highly stretchable polymer composite microtubes of poly(methyl methacrylate)/polypyrrole (PMMA/ PPy) were produced as a microarch shape by a meniscus-guided approach using colloidal solutions of the composite polymers. The polymer composite (PMMA/PPy) microarches show high stretchability up to 80% maintaining the electrical properties. Moreover, the microarches endure repeated stretching over 104 (9 102) cycles at 20% (80%) stretching without degradation of the electrical properties. Th stretch
Colloidal systems or colloids consist of microparticles or nanoparticles (solute) uniformly suspended in a liquid (solvent), also called colloidal suspensions. They can mimic and exhibit microscopic or atomic aspects of molecular and atomic systems. They have been increasingly studied because of their similarity with atomic systems. They can be microscopically observed by optical microscopes because they are large enough in size and slow in motion to be monitored; microscopic methods are very us
