Statics and dynamics of polymeric droplets on chemically homogeneous and heterogeneous substrates

Abstract: We present a molecular dynamics study of the motion of cylindrical polymer droplets on striped surfaces. We first consider the equilibrium properties of droplets on different surfaces, we show that for small stripes the Cassie-Baxter equation gives a good approximation of the equilibrium contact angle. As the stripe width becomes non-negligible compared to the dimension of the droplets, the droplet has to deform significantly to minimize its free energy, this results in a smaller value of the contact angle tha… Show more

“…reating and understanding phases of systems that are dissipatively coupled to the environment is of importance in research fields ranging from optics to biophysics (1)(2)(3)(4)(5)(6). One intriguing aspect of this openness is the possible existence of quantum states that are not otherwise accessible (7)(8)(9)(10).…”

“…Recently, oscillatory dynamics in open dye microcavity systems have been observed (6,16), a phenomenon that at large resonator losses crosses over to the relaxation oscillations known in laser physics. Unlike in a laser, the stochastic driving induced by grand canonical condensate fluctuations makes the system dynamics observable in stationary-state operation, which characterize the system's state by its second-order coherence.…”
