Estimate the value of the apparent contact angles (q*) for a composite interface formed by Water on an electrospun surface of PMMA + 44.1 wt% POSS.
The average fiber radius (R) = 500 nm and the average inter-fiber spacing (D) = 4.5 µm. The Young’s contact angle (q) for water on a spin-coated PMMA + 44.1 wt% POSS surface = 123°.
Also, compute the values of the two design parameters D* and A*. Note the capillary length (L cap) for water = 2.8 mm. Based on the value of A*, estimate the breakthrough pressure for water on this electrospun surface. Also, estimate the height of a column of water that would provide this breakthrough pressure.
