Parallel fibers with small open angles (approaching to 0°) encapsulate less liquid. (a) The interacting with water for two parallel glass fibers with the open angle of ∼0°, where a very small water membrane is formed. a1–a2 is the process of the parallel glass fibers approaching and contacting the water interface. a3–a4 is the process of the glass fibers aggregating together, forming a small water membrane when detaching from the water interface. (b) The corresponding model for two parallel glass fibers with the open angle of ∼0°.
