Measurement of Adhesion of In Situ Electrospun Nanofibers on Different Substrates by a Direct Pulling Method

Figure 2

(a) The schematic diagram of the direct pulling apparatus for adhesion measurement. (b) Detail drawing of the substrate showing that nanofibrous mesh (with width of c) was electrospun onto a substrate and a kraft paper strip was set between the as-spun mesh and the substrate. (c) A force (F) was applied on the electrospun membrane by pulling the kraft paper strip, thus forming a trapezoid shape and the bottom, and upper side length (d₁ and d₂) as well as the pulling height (h₁) and thickness of the electrospun mesh (h₂) were recorded and analyzed to obtain the adhesion force.
