Drop Generation and Surface Interaction

This lecture covers the generation of drops using inkjet printing technology, the interaction between drops and surfaces, film forming techniques, surface energy, drop spacing, printed line behaviors, and the impact of surface energy and topography on drop behavior. It also discusses the formation of spherical shapes by edge confinement, the printing of microlenses with arbitrary shapes, drops on patterned and structured surfaces, droplet drying on substrates, and the co-solvent strategy. The instructor presents experimental setups, drop landing, impact spreading, and the final shape of drops on substrates, emphasizing the importance of surface energy and contact angle in drop behavior.
