Artificial Nacre-Like Gold Nanoparticles–Layered Double Hydroxide–Poly(vinyl alcohol) Hybrid Film with Multifunctional Properties

Gold nanoparticles–layered double hydroxide–poly­(vinyl alcohol) (Au NPs–LDH–PVA) hybrid films have been successfully prepared for the first time by bottom-up assembly of pretreated Au NPs–LDH nanosheets and subsequent spin-coating of PVA. The cross sections of the as-prepared hybrid films resemble...

Description
Summary:Gold nanoparticles–layered double hydroxide–poly­(vinyl alcohol) (Au NPs–LDH–PVA) hybrid films have been successfully prepared for the first time by bottom-up assembly of pretreated Au NPs–LDH nanosheets and subsequent spin-coating of PVA. The cross sections of the as-prepared hybrid films resemble the brick-and-mortar structure of nacre. The tensile strength of the Au NPs–LDH–PVA hybrid film reaches a high value of 122 MPa, which is higher than that of a pure PVA film and surpasses the strength of natural nacre. Furthermore, we demonstrate that Au NPs–LDH–PVA hybrid films possess surface-enhanced Raman scattering and catalytic properties. Therefore, our report on the fabrication of multifunctional Au NPs–LDH–PVA hybrid films not only shows a feasible route to functionalizing artificial nacre-inspired materials but also potentially broadens applications of these nacre-like materials.
