From: 2D fracture-resistant high-entropy-oxide scaffold enabled multifunctional nanomembrane
a The HEO scaffold nanomembrane on the flexible circuit and Si wafer. b Photographs of the nanomembrane TFE before and after being immersed in water. c Load-displacement curves for pull-off tests of bare and nanomembrane-covered PDMS bulks. d Visible transmittance and reflectance spectra of the nanomembrane on a glass substrate with the bare glass as a reference. The inset shows a photograph of the circuit visible through the nanomembrane. e Photographs and height images of the nanomembrane TFE on the flexible circuit before and after being stretched and bent in water. f Uniaxial tension to crack initiation at a failure strain of εf and (g) fatigue tests of 2000 cycles at 5% strain for the nanomembrane on PDMS. h Photographs and height images of the nanomembrane TFE on Cu film before and after being bent in water. i Height images of the nanomembrane TFE on the Cu film after 24 h of 85 °C/85%RH accelerated life test, and j the corresponding high-resolution XPS spectra of Cu LM2 with and without the nanomembrane TFE. Source data are provided as a Source Data file.
