Structural colour of polyester fabric coated with Ag/TiO₂ multilayer films

Abstract

Silver/titanium dioxide (Ag/TiO 2 ) multilayer films with structural colours on polyester fabric were fabricated using direct current (DC) magnetron sputtering. The bright and variable structural colourations of polyester fabrics coated with an Ag/TiO 2 film were investigated with GretagMacbeth Color-Eye 7000A spectrophotometer. The compositions, surface morphologies and microstructure of multilayer films deposited on polyester fabrics were also analysed by X-ray photoelectron spectroscopy, Scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results indicated that the structural colours varied with the thickness of TiO 2 thin layer in Ag/TiO 2 multilayer films. The TiO 2 thin layer thicknesses were 42, 65.6, 82, 98.4 and 114.8 nm, and the samples colours became purple, light blue, blue, pink and dark red, respectively. The creation of colours was coincident to film interference principle. XRD analysis revealed that there were four diffraction peaks for Ag/TiO 2 multilayer film at 38, 44, 64 and 77°of 2θ, corresponding to ( 110), ( 200), ( 220) and (311) Ag crystal planes and that TiO 2 structure in Ag/TiO 2 multilayer film was non-crystalline.

Properties and application of multi-functional and structurally colored textile prepared by magnetron sputtering

“…Through our previous experimental research, Ag/TiO 2 composite films deposited on the surface of textiles using laboratory magnetron sputtering equipment can not only create beautiful and colorful structural colors but also has excellent optical and electrical properties [25][26][27]. At the same time, polyester fabrics were often used as substrates because of low cost and wide application.…”

Review on Fabrication of Structurally Colored Fibers by Electrospinning

“…Several conventional techniques have been employed to produce TiO2 films, including conventional sol-gel method [48,49], vapor deposition method [50,51], and liquid phase deposition [52,53]. Chen and co-workers [54] successfully used an effective method named the atomic layer deposition (ALD) technique to fabricate TiO2 coatings with vibrant and uniform structural colors using black carbon fibers as substrates, showing excellent laundering durability.…”

“…Since the discovery of an approach for synthesizing monodisperse polymer colloids by Vanderhoff, this synthetic method has been used to prepare diverse polymeric colloids, including homopolymer colloidal nanoparticles as well as copolymer nanoparticles, besides inorganic colloidal nanoparticles [58,59].

“…SiO 2 nanoparticles incorporated with gold has been prepared to form colloidal spheres (Au@SiO 2 ) with core-shell shapes, which can serve as the building blocks for photonic applications [9]. Yuan et al [50] reported structural colors on polyester fabric with the coating of silver(Ag)/TiO 2 films made by magnetron sputtering. The resultant samples with diverse colors of purple, light blue, blue, pink, and dark red could be displayed by controlling different thickness of TiO 2 thin films.…”

“…It is widely used in optical thin films, solar energy, and semiconductor photocatalytic antibacterial agents Antibacterial and ultraviolet protective neodymium-doped TiO 2 film coated on polypropylene nonwoven fabric via a sputtering method due to its non-toxicity and durable antibacterial properties. Coating TiO 2 film on textiles can obtain structural coloring, [9][10][11][12] electrical, 13 antibacterial, 14 ultraviolet (UV) protective, 15,16 photocatalytic, [17][18][19] and other properties. TiO 2 can be even used to improve the adhesion of nanoparticles on the fabric surface.…”
