“…This means that they develop an internal magnetization rapidly only in the presence of an external magnetic field, and once the magnetic field is removed, they lose their net magnetization completely. Due to their rapid response to a magnetic field and the ability to form photonic crystal arrays precisely and conveniently with tunable optical properties in a liquid medium (aqueous or nonaqueous), they have been studied for their potential use as colorimetric sensors, invisible photonic printing, flexible color display, security materials and structurally colored fibers . When Fe 3 O 4 nanoparticles have sufficient surface charge, they maintain colloidal stability due to electrostatic interactions.…”

“…Using magnetic particles to fabricate smart fiber, a flexible strain‐responsive photonic fiber has been prepared, based on Fe 3 O 4 @C super‐paramagnetic nanoclusters embedded in a PAm matrix . The magnetic clusters form 1D chain‐like photonic structures in the fiber, where the structural color reversibly changes upon stretching/squeezing.…”

Stimuli-responsive colors are a unique characteristic of certain animals, evolved as either a method to hide from enemies and prey or to communicate their presence to rivals or mates. From a material science perspective, the solutions developed by Mother Nature to achieve these effects are a source of inspiration to scientists for decades. Here, an updated overview of the literature on bioinspired stimuli-responsive color-changing systems is provided. Starting from natural systems, which are the source of inspiration, a classification of the different solutions proposed is given, based on the stimuli used to trigger the color-changing effect.

“…For the preparation of structurally colored fibers, the construction of periodic alignment of micro-and nano-materials within the fibers is a difficult and key problem. Shang et al proposed a magnetically assisted self-assemble process to obtain the structurally colored fibers [125]. Induced by an external magnetic field, the superparamagnetic colloidal spheres were arranged into the one-dimensional chainlike structure and embedded in the stretchable PDMS matrix.…”

The research and applications of fiber materials are directly related to the daily life of social populace and the development of relevant revolutionary manufacturing industry. However, the conventional fibers and fiber products can no longer meet the requirements of automation and intellectualization in modern society, as well as people's consumption needs in pursuit of smart, avant-grade, fashion and distinctiveness. The advanced fiber-shaped electronics with most desired designability and integration features have been explored and developed intensively during the last few years. The advanced fiber-based products such as wearable electronics and smart clothing can be employed as the second skin to enhance information exchange between humans and the external environment. In this review, the significant progress on flexible fiber-shaped multifunctional devices, including fiber-based energy harvesting devices, energy storage devices, chromatic devices, and actuators are discussed. Particularly, the fabrication procedures and application characteristics of multifunctional fiber devices such as fiber-shaped solar cells, lithium-ion batteries, actuators and electrochromic fibers are introduced in detail. Finally, we provide our perspectives on the challenges and future development of functional fiber-shaped devices.

“…Owing to this reversible change, the chain-like fibre structures can show brilliant colours ranging from red to green. As these fibres are conductive, they can also be used as sensors to detect deformation (Shang et al 2015). Yuan et al suggested a new structural colouration technique to fabricate structurally coloured fibres using electrospinning.…”

Gao et al. have proposed a facile method of silica nanoparticle synthesis called the solvent varying technique (SVT). Silica nanoparticles (SNPs) have been synthesized using the SVT. The diameters of the SNPs produced by these recipes are sensitive to drying temperature especially when they are used to form photonic crystal films on the surface of textiles. The colour appearance of the coated fabrics can be affected by unused reactants from the colloidal suspensions. These form a thin layer on the surface of the SNPs, which can adversely affect the constructive interference of light from the photonic crystal. In this paper, the original SNP solutions have been processed using a centrifuge and solvent replacement technique in order to reduce this problem. A TEM was used to record the morphology of the surface of the original and centrifuged particles. The resultant images show that there were fewer impurities present on the surface of the centrifuged SNPs than that of the original SNPs. DLS was used to measure the diameters and dispersion of the original and the centrifuged particles. A spectrophotometer was used to measure the reflectance of the samples. The chromaticities of the coated fabrics using both the original and centrifuged SNPs dried at a range of temperatures (40°C, 60°C, 80°C and 100°C) have been compared. It was determined that the centrifuged SNPs could be dried at higher temperatures than previously reported with little effect on the colour appearance of the photonic crystals. Highlights• The centrifuge and solvent replacement technique can remove unused reactants from the surface of silica nanoparticles produced using the solvent varying technique. • These centrifuged SNPs (C-SNPs) have been dried over a greater range of temperatures than previously reported and the C-SNPs produce uniform photonic crystals on coated polyester. • The photonic crystals produced from the centrifuged SNP solutions produce a narrower bandwidth of wavelength reflection. This produces a sharper reflection peak and more chromatic surface coatings.
