摘      要：Curvilinear self-propelling of droplets has attracted great interest in the past few decades due to their irreplaceable roles in many *** understanding is that a droplet moves only along a preset channel formed by morphology or chemi-cal *** programmable curvilinear droplet motion independent of a preset channel remains greatly ***,we report a programmable curvi-linear self-propelling of droplets(circle,divergence,and convergence)based on the collaboration of the curvilinear wetting gradient and the Leidenfrost *** design achieves motion trajectory in a well-controlled manner as well as high velocity and long distance of droplet transport independent of the preset ***,the motion behaviors of droplets could be predicted accurately by theoretic *** envi-sion that our unique design could manifest extensive practical applications in fluidic devices,liquid transport,and heat transfer systems.
