In an example, a thermal interface material includes a polymeric phase-change material.

In an example, a thermal interface material includes a polymeric phase-change material.

Polymer composite photonic crystal materials are disclosed as coatings which have high reflection (>30%) in a specific range of the electromagnetic spectrum, such as ultraviolet (<400 nm), visible (Vis, 400 nm-700 nm), or near-infrared radiation range (NIR, 700-2000 nm), and relatively low reflection (<20% reflection) in a second, different range of the electromagnetic spectrum. Surprisingly, it was found that through a formulation and additives approach, the optical properties of polymer composite photonic crystal films can be selectively modified from a variety of different coating methods, including spray deposition.

The invention relates to a formable composition for the preparation of engineered stone comprising a cobalt free prepromoted unsaturated polyester resin system, an inorganic particulate material and a peroxide component. The invention also relates to a method for the preparation of engineered stone as well as to the use of the cobalt free prepromoted unsaturated polyester resin system for the preparation of engineered stone.

Polymer composite photonic crystal materials are disclosed as coatings with topcoats having high reflection (>30%) in a specific range of the electromagnetic spectrum, such as ultraviolet (<400 nm), visible (Vis, 400 nm-700 nm), or near-infrared radiation range (NIR, 700-2000 nm), and optionally a relatively low reflection (<20% reflection) in a second, different range of the electromagnetic spectrum. Surprisingly, it was found that through a multi-layer coating approach, the optical properties of polymer composite photonic crystal films can be selectively modified from a variety of different coating methods, including spray deposition.
