Special Issue Information

Dear Colleagues,

The increasing demands of highly integrated flexible devices are promoting the development of new materials, new designs, and new fabrications of not only main structures, but also the coatings of whole devices. With these coatings, the devices are able to be applied to broader applications as they are more compatible with many extreme environments and help improve performance. They have a wide range of applications that can benefit biomedicines. Besides assisting devices, the coatings are able to achieve unique and independent functions. The developments of the coatings include the efforts of advanced materials, designs, and also fabrications.

This scope of this Special Issue will serve as a forum for papers in the following areas:

  • Material development with experimental research for device coatings in the areas of new synthesised materials, combinations of fillers and substrates, or others;
  • Structures and designs of coatings of devices helping devices gain better performance;
  • Fabrication procedures to improve coating properties, including, but not limited to, spray coating, CVD, PVD, and 3D printing;
  • Extended/integrated functions of coatings and their corresponding applications, like lower impedance to gain better signals and development of films, coatings, or related materials for biomedical applications;
  • Computer modelling and simulations of coatings in the areas of materials, structural designs, applications, etc.;
  • Recent developments of coatings considering many areas, including, but not limited to, the materials, or the mechanical, electrical, and chemical properties.

Silver nanowire transparent conductive films (AgNW TCFs), as the novel transparent electrode materials replacing ITO, are anticipated to be applied in numerous optoelectronic devices, and slot-die coating is currently acknowledged as the most suitable method for the mass production of large-sized AgNW TCFs. In this study, sodium carboxymethyl cellulose (CMC) and polyvinyl alcohol (PVA), as film-forming aids, and AgNWs, as conductive materials, were utilized to prepare a specialized AgNW ink, and a slot-die coating is employed to print and prepare AgNW TCFs. The optoelectrical properties of AgNW TCFs are optimized by adjusting the compositions of AgNW ink and the process parameters of slot-die coating. The suitable compositions of AgNW ink and the optimal parameters of slot-die coating are a CMC type of V, a PVA volume of 1 mL, a AgNW volume of 1.5 mL, a volume ratio of 30 and 45 nm AgNWs (2:1), and a coating height of 400 μm. The resultant AgNW TCFs achieve excellent comprehensive optoelectronic performance, with a sheet resistance of less than 50 Ω/sq, a visible light transmittance exceeding 92%, and a haze below 1.8%. This research provides a valuable approach to producing AgNW TCFs on a large scale via the slot-die coating. Full article
