A material platform with controllable emissivity and fabrication methods are provided that permit the manipulation of thermal radiation detection and IR signal modulation and can be adapted to a variety of uses including infrared camouflage, thermal IR decoys, thermo-reflectance imaging and IR signal modulation. The platform is a multilayer W.sub.xV.sub.1-xO.sub.2 film with different W doping levels (x values) and layer thicknesses, forming a graded W-doped construct. In WVO.sub.2 films with a total thickness <100 nm, the graded doping of W spreads the originally sharp metal-insulator phase transition (MIT) to a broad temperature range, greatly expanding the temperature window for emissivity modulation.

Composite structures composed of a coating applied to a substrate and provided, along with a process for applying a coating to a substrate to form the composite structure. Coatings described herein provide at least one of the following properties: nano-sized surface roughness; enhanced hydrophobic function; high transmittance; improved hardness; improved scratch resistance; and desirable bending properties. The coating method includes mixing coating particulates having an average particle diameter of 1 μm or less with a transfer gas, transferring the mixture to an application nozzle, and spraying coating particulates on the substrate under low pressure conditions to form a coating having an average particle diameter of 100 nm or less.

One or more aspects of the disclosure pertain to an article including a film disposed on a glass substrate, which may be strengthened, where the interface between the film and the glass substrate is modified, such that the article has an improved average flexural strength, and the film retains key functional properties for its application. Some key functional properties of the film include optical, electrical and/or mechanical properties. In one or more embodiments, the interface exhibits an effective adhesion energy of about less than about 4 J/m.sup.2. In some embodiments, the interface is modified by the inclusion of a crack mitigating layer containing an inorganic material between the glass substrate and the film.
