“…The chemical structure of annealed PbSe thin films is further investigated by FTIR, as shown in Figure . There are three significant absorption peaks at 548–820, 840–1200, and 1230–2000 cm –1 of the as-grown VPD-PbSe film, corresponding to the SeOSe bending vibration and PbSe and CO stretching vibrations, − respectively. After sensitization, the SeOSe and PbSe vibration peaks significantly increase, and the wide peaks at 1900–2500 and 3000–4000 cm –1 corresponding to the PbI stretching vibration − are detected, indicating the formation of PbI 2 , which is in agreement with the XRD result.…”

The broad application of lead selenide (PbSe)-based uncooled midinfrared (MIR) detectors has been hindered by the nonuniformity of wafer-level films prepared by the conventional chemical bath deposition (CBD) method. Herein, using a vapor phase deposition (VPD) approach, we demonstrate the deposition of 3 in. wafer-scale uniform PbSe thin films with thicknesses of up to 1.5 μm. To trigger the MIR response, the as-grown films were sensitized at an elevated temperature in an oxygen−iodine atmosphere. We discovered that the key to spark off the MIR response of the PbSe detector originated from the self-assembled rodlike microstructures in the thin films, which can be controlled by the I 2 /PbSe flux ratio in the VPD process. At room temperature, the thin film detector exhibits an excellent optoelectronic performance, with detectivity up to 2.4 × 10 9 cm Hz 1/2 W −1 achieved under optimized conditions. Our results show that the VPD method opens up a new avenue to the industrialization of uncooled lead-salt MIR detectors.

“…One of the most popular groups of flame retardants used for polyurethanes are nitrogen-based compounds and, among them, the most essential is melamine and its derivatives [81]. The high efficiency of melamine in reducing the flammability of polymer materials is attributed to the complex mode of action.…”

Polyurethanes are a very important group of polymers with an extensive range of applications in different branches of industry. In the form of foams, they are mainly used in bedding, furniture, building, construction, and automotive sectors. Due to human safety reasons, these applications require an appropriate level of flame retardance, often required by various law regulations. Nevertheless, without the proper modifications, polyurethane foams are easily ignitable, highly flammable, and generate an enormous amount of smoke during combustion. Therefore, proper modifications or additives should be introduced to reduce their flammability. Except for the most popular phosphorus-, halogen-, or nitrogen-containing flame retardants, promising results were noted for the application of clays. Due to their small particle size and flake-like shape, they induce a “labyrinth effect” inside the foam, resulting in the delay of decomposition onset, reduction of smoke generation, and inhibition of heat, gas, and mass transfer. Moreover, clays can be easily modified with different organic compounds or used along with conventional flame retardants. Such an approach may often result in the synergy effect, which provides the exceptional reduction of foams’ flammability. This paper summarizes the literature reports related to the applications of clays in the reduction of polyurethane foams’ flammability, either by their incorporation as a nanofiller or by preparation of coatings.

“…2 Polyethylene terephthalate (PET) is an important thermoplastic polymer material 3 and one of the five primary engineering materials. 4,5 However, the widespread application of PET materials is limited by its inherent flammability and combustion process, showing a low oxygen index, high heat release rate (HRR), and limited carbon formation. 6,7 The most promising approach toward resolving the flammability issue is imparting the flame retardancy feature to PET materials.…”
