The work of adhesion at the interface of electrospunmembrane andrigid substrate is measured by a shaft-loaded blister test (SLBT).Poly(vinylidene fluoride) (PVDF) were electrospun with an averagefiber diameter of 333 ± 59 nm. Commercial cardboard with inorganiccoating was used to provide a model substrate for adhesion tests.In SLBT, the elastic response PVDF was analyzed and its adhesion energymeasured. The average value of the adhesion work is 206 ± 26mJ/m2. Elastic modulus of electrospun membrane obtainedby SLBT is found to be 23.42 ± 2.69 MPa, which is consistentwith the value obtained from standard tensile tests. The results showSLBT presented a viable methodology for evaluating the adhesion energyof electrospun polymer fabrics. [ABSTRACT FROM AUTHOR]
