Fluid-driven approaches for precision surface patterning - Sepideh Khodaparast
LIFD 5th Celebration Event | Sepideh Khodaparast | 26th January 2024
Micro/nano-patterned surfaces have found increasing applications in various emerging technologies thanks to their supreme functionalities related to wetting, self-cleaning, adhesion, acoustics and interactions with biological entities. Developing practical techniques to fabricate larger areas of such surfaces in a well-controlled and cost-effective manner, however, remains challenging. After a brief introduction to biomimetic engineering, this presentation will showcase examples of how natural inspirations can guide us to achieve functional design and sustainable manufacturing of scalable structured surfaces. I will discuss spontaneous yet predictable interfacial architectures generated through fluid-based methods that exploit thermodynamic phase change processes, namely condensation and crystallisation. Finally, I will demonstrate examples of the interfacial functionalities emerging from such surface structures.
