TLDR
Spray coating in the context of crack template is a powerful method for producing transparent heaters, which is shown for the first time in this work.Abstract:
Transparent conducting electrodes (TCEs) have been made on flat, flexible, and curved surfaces, following a crack template method in which a desired surface was uniformly spray-coated with a crackle precursor (CP) and metal (Ag) was deposited by vacuum evaporation. An acrylic resin (CP1) and a SiO2 nanoparticle-based dispersion (CP2) derived from commercial products served as CPs to produce U-shaped cracks in highly interconnected networks. The crack width and the density could be controlled by varying the spray conditions, resulting in varying template thicknesses. By depositing Ag in the crack regions of the templates, we have successfully produced Ag wire network TCEs on flat-flexible PET sheets, cylindrical glass tube, flask and lens surface with transmittance up to 86%, sheet resistance below 11 Ω/□ for electrothermal application. When used as a transparent heater by joule heating of the Ag network, AgCP1 and AgCP2 on PET showed high thermal resistance values of 515 and 409 °C cm2/W, respectively, wi...read more

Transparent superhydrophobic/superhydrophilic coatings for self-cleaning and anti-fogging
TL;DR: In this paper, a high transparent super-hydrophobic surface covered with hollow spheres has been fabricated through a carbon template route, and the as-prepared coating without treating with low surface energy materials showed super-hdrophilic and anti-fogging properties while displayed super hydrophobic characteristics after surface modification.
