Physical and Chemical Properties of Cotton Fiber‐Based Composites

Infrared nanospectroscopy depth-dependent study of modern materials: morpho-chemical analysis of polyurethane/fibroin binary meshes

“…conventional spectroscopies, do not typically reach the spatial resolution needed for single nano-fiber detection and could only look at composites as quasi-homogeneous materials. 7,8 In the present study, we propose the use of nano-resolved IR microscopy, namely infrared scattering-type scanning near field optical microscopy (IR s-SNOM), supported by micro Attenuated Total Reflection (ATR) Fourier Transform Infrared (FTIR) imaging, to address the study of a binary fibrous material named Silkothane®. 9 In Silkothane® the combination of natural silk fibroin (SF) and synthetic medical grade polyurethane (PU) proved to be highly suitable for TE applications.…”

“…stiffness), while PU is characterized by good deformability in response to external solicitations, proving to be suitable for multiple applications, e.g. vascular prostheses 7,10 and cardiac patches. 8,11 Silkothane® is obtained in the form of nanofibrous matrices from the processing of a SFPU blend via electrospinning.…”
