Electrospun Mats: From White to Transparent with a Drop
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 we...

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. The obtained results indicate that changes on the optical response produced by water contact are different according to the mat thickness: samples with smaller thicknesses can act as a water sensor with a persistent response over time, while samples with thicknesses greater than 7 µm can act as sensors for drying time. © 2018 WILEY-VCH Verlag GmbH & Co.
