Bioinspired Ternary Artificial Nacre Graphene Oxide/Carboxyl Functionalized Single-Walled Carbon Nanotubes/Konjac Glucomannan with Enhanced Mechanical Properties.

Inspired by the nacre layered multistage structure and high toughness and strength of the unity of mechanical properties, a graphene oxide/carboxyl functionalized single-walled carbon nanotubes/konjac glucomannan (GO-SC-KGM) nanocomposite is successfully fabricated through a vacuum filtration method for the first time. The GO nanosheets with carboxyl and hydroxyl groups, SC with carboxyl groups, and the KGM molecule chains with abundant hydroxyl groups could easily form hydrogen bonding networks, resulting in a strong interface interaction. The tensile strength of prepared GO-SC-KGM nanocomposites reaches 311.

Bioinspired design and assembly of layered double hydroxide/poly(vinyl alcohol) film with high mechanical performance.

Inspired by the hierarchical structure and excellent mechanical performance of nacre, LDH nanosheets with an appropriate aspect ratio to withstand significant loads and at the same time allow for rupture under the pull-out mode were synthesized as artificial building blocks for the fabrication of nacre-like films. Multilayered PVA/LDH films with a high tensile strength and ductility were prepared for the first time by bottom-up layer-by-layer assembly of pretreated LDH nanosheets and spin-coating of PVA. The weight fraction of inorganic LDH platelets in the hybrid PVA/LDH films (wp) was controlled by changing the concentration of PVA solution applied in the spin-coating process.
