    Constrained by Metal Substrates
  title_type: original
  lang: en

## Description

- description: "In situ structural analysis under loads of amorphous\r\nadhesives
    buried between metal substrates was conducted by using\r\nsynchrotron X-ray nanobeam
    diffraction and an embedded local\r\nstrain probe. Thermoplastic resins composed
    of polyrotaxanes,\r\nfeaturing bulky cyclic molecules threaded with a linear polymer,\r\nwere
    sandwiched between stainless-steel substrates with diffraction\r\ndata attributed
    to the correlation distance between their cyclic\r\ncomponents being collected.
    The nanobeam was irradiated parallel\r\nto the substrates and scanned, while distances
    from the substrate\r\nwere changed to obtain depth profiles of correlation distance.\r\nThen,
    tensile loads were applied stepwise to the sandwiched sample\r\nto reveal local
    strain distributions of the resins under different\r\nloads. Different strain
    distributions and their changes with loads\r\nwere observed in resins with different
    adhesive strengths. The sample with strong adhesion showed pronounced strain localization
    near the interface between resin and substrate, whereas the weak sample displayed
    moderate strain further from the interface, with negligible strain near the interface.
    When the load increased, localized strain saturation occurred, followed by strain
    propagation into adjacent areas, indicative of a typical strain delocalization
    process associated with strain hardening near a highly constrained interface by
    substrates. This analysis elucidated the deformation and fracture processes of
    buried polymers, offering insight into those adhesive strength differences phenomenologically.
    This in situ analysis of local strain distribution contributes to comprehending
    adhesion mechanisms required for advancing multimaterialization technology and
    holds applicability to materials with buried interfaces such as nanocomposites."
