Hydrophobic silica-aerogel integrated polyacrylonitrile nanofibers

Journal of Industrial Textiles, 2020
Owing to its high specific surface area, high thermal stability and excellent thermal insulation, silica aerogel is used as an insulating material in protective clothing. In this study, the hydrophobicity and thermal insulation properties of the electrospun polyacrylonitrile (PAN) nanofibers were enhanced by integrating silica aerogel (SA), which was ...

Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials

Advanced Science, EarlyView.
ABSTRACT Stabilizing multiple elements within a single phase enables the creation of advanced materials with exceptional properties arising from their complex composition. However, under equilibrium conditions, the Hume–Rothery rules impose strict limitations on solid‐state miscibility, restricting combinations of elements with mismatched crystal ...
