Probing the nano-scale architecture of diamond-patterned electrospun fibre mats by synchrotron small angle X-ray scattering

Abstract

A diamond-patterned polyvinylpyrrolidone (PVP) fibre mat manufactured by electrospinning onto a structured target was studied by the combination of electron microscopy and synchrotron small angle X-ray scattering. Multi-scale hierarchical structure analysis revealed the relationship between different morphological levels, from an overall mat layout to individual fibres to polymer fibril orientation within them.
