Graphene Oxide/Reduced Graphene Oxide Enhanced Noniridescent Structural Colors Based on Silica Photonic Spray Paints with Improved Mechanical Robustness

Abstract

In contrast to traditional pigment colors, structural colors have developed a great potential in practical applications, thanks to their unique nonfading and color tunable properties; especially amorphous photonic structures with noniridescent structural colors have attracted considerable attention and their applications have expanded to more fields. Herein, graphene oxide (GO) and reduced graphene oxide (RGO) enhanced noniridescent structural colors with excellent mechanical robustness were established by a time-saving approach named spray coating, which allows for rapid fabrication of angular independent structural colors by spraying different photonic spray paints (PSPs) to ensure color multiplicity that was adjusted by the silica nanoparticles (SiO2 NPs) sizes onto the substrates. The incorporation of poly(methyl methacrylate-butyl acrylate) (PMB) improved the adhesion existing among SiO2 inter-nanoparticles and between SiO2 NPs and the substrates, taking advantages of the low glass transition temperature (Tg) of butyl acrylate derivative polymer and made PMB embedded PSPs coated patterns being imparted with good mechanical robustness and abrasive resistance. The peculiar light adsorption of GO and RGO across visible light spectrum facilitate higher color saturation. The improvement in color saturation of GO and RGO doped PSPs is expected to boost the promising applications in structurally colored paintings, inks and other color-related optical fields.

Prediction and Inverse Design of Structural Colors of Nanoparticle Systems via Deep Neural Network

“…Color generation from the assembly of nanometer-or submicron-sized structures has been of great interest for various fields including chromatic displaying [1][2][3], color printing [4,5], and biomedical imaging [6]. By exploiting the light-matter interaction in the designed structures, the generated colors are superior to the traditional pigmentary colors in many ways, due to their large tunability, resistance to bleaching, and reduced dependence on toxic materials.…”

Facile preparation of amorphous photonic structure towards rapid temperature sensing and antibacterial textile

“…16 Therefore, the key points to prepare APS films with bright structural colors are not only to avoid the orderly assembly of colloidal crystals, but also to add appropriate black dopant to absorb incoherent scattered light and improve the saturation of structural color. Common black dopants, including carbon black, 17 cuttlefish ink, 18 graphene, 19 polydopamine , 20 acetylene black 21 etc have been widely researched. However, appreciated method to prepare APS films and extend their applications are still highly needed.…”

Wall Latex Paint with Graphene Oxide Incorporation

“…The high resistivity of graphene can produce durable coatings that do not crack and are resistant to water and oil; its excellent electrical and thermal conductivity can be used to make various conductive paints, and its strong barrier effect can contribute to antioxidant, antiscratch, resistant, anti-UV, and antibacterial paints. Graphene paints are gaining ground in the current market due to such properties and are already seen in graphic forms for printing, conductors for supercapacitors, and surface coatings, such as sprays and epoxy resins, among other applications [8][9][10].…”
