Results showing how transmittance varies under the action of water are presented.

description	In this article, the transparency of hydrophilic electrospun mats is studied. Results showing how transmittance varies under the action of water are presented. It is observed that swelling plays a crucial role in the transmittance of the material, changing it from opaque to transparent when it is wet. Atomic force microscope measurements show that the diameter distribution of nanofibers is modified during both the wetting and the drying of the mats. Using these distributions and modeling the change in the relative refractive index as a composite material, a qualitative explanation of the mat scattering behavior by using the Mie scattering theory for cylinders has been done.
