a Scanning electron microscopy (SEM) image of the natural cuttlebone. b Structural design of the RCWSM. c SEM image of the RCWSM. d Multiple interactions of building blocks within the RCWSM. e The rheological properties of the GB/PVA/qCNF initial gel of rigid cavity layer. GB glass bubble, PVA polyvinyl alcohol, qCNF quaternized cellulose nanofiber. Insets are photographs of the initial gel at the fluid stage (left) and gel stage (right). f Solid-state nuclear magnetic resonance spectra (11B) of the GB/PVA/qCNF, GB/PVA, GB/qCNF, and GB samples. g B 1s X-ray photoelectron spectroscopy (XPS) of the GB and GB/PVA samples.
