Fig. 8: Simulation of selective treatment.

a Schematic diagram of printing with selective treatment. b Simulated single droplet scales of different cases. c Macroscopic contact angle and cross-section shape of different cases. d Simulated multidroplet morphology of different cases. a Is the top view of the computational region to realize selective treament, the contact angle of different regions are shown in the figure and droplets are deposited by the numerical order. In b, the number/number mean θ_s1/θ_s2 and this figure shows the simulated width and length of single droplet in different selective treatment conditions. In c, the number/number-number of different cases mean θ_s1/θ_s2-width of θ_s1 region, and the vertical coordinate is the macroscopic contact angle, and d shows the top view of simulated morphology.
