Fig. 4. Static mechanical stretching of LGEPM and the critical pressure of gas and liquid during stretching.

Fig. 4

(A) Pore size depedence of the critical pressure of gas and liquid transported through the LGEPM at a certain flow rate (1000 μl/min). Inset is the theoretical model of the critical pressure of LGEPM with different pore sizes at different flow rates. (B) Schematic illustration of one- and two-dimensional stretch applied to the LGEPM, and upon deformation, the LGEPM elongates in the direction of stretching. Inserted figures depict the stress distribution surrounding the pore in the one- and two-dimensional stretching process. Dashed circles represent the initial size of the pores. (C) Critical pressure of gas and liquid flowing through the LGEPM as a function of one-dimensional strain. Insets are the representative optical images of LGEPM during the deformation process. Scale bar, 200 μm. (D) Critical pressure of gas and liquid flowing through the LGEPM in various pore sizes without stretch and with two-dimensional stretch (50% strain biaxially). Gating liquid in (A), (C), and (D) is silicone oil. EPM is silicone rubber.
