Elasto-Capillary Shape Memory

We view elasto-capillarity as a kinetic process and try to answer these fundamental questions: (i) What is the time scale of elasto-capillary coalescence as limited by liquid diffusion, viscosity and pillar viscoelasticity? (ii) What is the effect of this time scale on the final self-assembly configuration Due to elasto-capillary forces, arrangements of filaments can change their shape. These filaments, which are similar to biological cilia can have many interfacial functions such as resistance to bio-film formation, adhesion and texture/color change.  We are investigating beating, bifurcations and other dynamic effects in elasto-capillary phenomena, and engineering these effects to create shape memory textures.
