“…Tungsten oxide nanoparticles have also been used for the preparation of electrochromic inks [176,177,178]. As an example, Laia and co-workers prepared water based formulations containing these nanoparticles that were inkjet printed on flexible ITO-coated polyethylene terephthalate (PET) substrates to form both, the working electrode and the counter electrode having an electrolyte in between.…”

Inkjet printing, traditionally used in graphics, has been widely investigated as a valuable tool in the preparation of functional surfaces and devices. This review focuses on the use of inkjet printing technology for the manufacturing of different optical elements and photonic devices. The presented overview mainly surveys work done in the fabrication of micro-optical components such as microlenses, waveguides and integrated lasers; the manufacturing of large area light emitting diodes displays, liquid crystal displays and solar cells; as well as the preparation of liquid crystal and colloidal crystal based photonic devices working as lasers or optical sensors. Special emphasis is placed on reviewing the materials employed as well as in the relevance of inkjet in the manufacturing of the different devices showing in each of the revised technologies, main achievements, applications and challenges.

“…However, promising results in achieving exible electrochromic metal oxide lms (WO 3 and V 2 O 5 ) were recently reported. [21][22][23][24] These lms were obtained by depositing the respective nanoparticle dispersion on exible plastic substrates via an inkjet printing technique. Another mechanically attractive system with potential advantageous electrochromic properties may be our bio-inspired V 2 O 5 -LC polymer composite.…”

Electrochromic properties of self-organized multifunctional V₂O₅–polymer hybrid films

Bio-inspired V 2 O 5 -polymer hybrid films were prepared following a one-step self-organization procedure based on liquid crystal formation of organic and inorganic components. These materials were previously reported to exhibit advantageous mechanical properties, comparable to biomaterials, such as human bone and dentin. Here, we show that these hybrid films prepared via a fast and simple synthesis procedure have an additional function as an electrochromic material, exhibiting a long-term cycle stability under alternating potentials. The structures were found to remain intact without visible changes after more than hundred switching cycles and storing the devices for several weeks. Consequently, this multifunctional V 2 O 5 -polymer hybrid system shows great promise for various technical applications.Organic-inorganic biomaterials, such as bone and nacre, consist of high, stiff and brittle, mineral fractions, which are embedded in a so organic matrix.1,2 These materials exhibit a pronounced hierarchical structure and a controlled coupling at the interface between organic and inorganic components. These structural characteristics contribute to their outstanding mechanical properties, combining both high stiffness and toughness.3-6 Very recently, we developed a biomimetic fabrication concept for the synthesis of organic-inorganic composites based on liquid crystal (LC) formation of organic and inorganic components.7 The LC 'gluing' polymer used was a statistical polyoxazoline with pendant cholesteryl and carboxyl side chains, enabling the polymer, on the one hand, to form chiral-nematic lyotropic phases on the length scale of several hundreds of micrometers upon shearing, and on the other hand, to selectively bind to nanoparticle faces via electrostatic interactions or hydrogen bridges.7,8 The inorganic nanoparticles, Laponite 7 and vanadium pentoxide (V 2 O 5 ), 8 are anisotropic in shape and consequently, were also able to form LC phases. V 2 O 5 -LC polymer composites structured on six hierarchical levels exhibiting a well-dened nanostructure and a hierarchical structuring on the length scale of several hundreds of micrometers were fabricated via this one-step selforganization process.8 Long-range orientation of the polymeric lyotropic phase was induced by rotational shearing by means of a shear cell. Remarkably, these materials exhibit advantageous mechanical properties, comparable to mechanical properties of natural hierarchically structured organic-inorganic composites like human bone and dentin (data obtained by nanoindentation; a video visualizing the bending performance of the composite is available in the ESI †).8 In this study, we investigated these materials regarding their electrochromic performance, a second feature of this composite system, besides mechanical reinforcement.Electrochromism of thin lms of transition-metal oxides, such as tungsten oxide (WO 3 ) or V 2 O 5 , have been previously studied. Upon cation intercalation (reduction) of the metal oxide, a change in absorbance in the visib...

An aqueous suspension of WO3/poly(4-(2,3-dihydrothieno[3,4-b]-[1,4]dioxin-2-yl-methoxy)-1-butanesulfonic acid) (PEDTS) hybrid nanoparticles (NPs) is prepared by air-assisted oxidative polymerization and simultaneous attachment of PEDTS on WO3-NPs, and used for electrochromic (EC) film fabrication via air-brush spraying. The hybrid EC device exhibits enhanced EC properties compared to the ones based on WO3-NP or PEDTS alone.
