Carbon Doped Boron Nitride Nano‐Coatings for Durable, Low Emissivity Glass Windows
Abstract
AbstractEnergy‐efficient, durable low‐emissivity (low‐E) glass windows are in demand for reducing energy consumption and comfortable living environments. However, commercial low‐E coating materials are expensive, prone to abrasion, and hence coated only on the interior side of windows, limiting their energy efficiency. Here, a new material is introduced, namely chemically inert and transparent carbon (C) doped boron nitride (BN) nano‐coatings on glass surfaces at room temperature using pulsed laser deposition, that shows promising long‐wave infrared emissivity (εLWIR ≈0.42). The hydrophilic C‐BN coatings on glass show excellent environmental stability including high temperature‐high humidity degradation resistance, UV‐light, thermal cycling, freezing condition, and saltwater resilience. Furthermore, the coating shows promising adhesion on the glass surface with full scratch protection. In an actual‐sized building energy simulation for cold‐climates, the intended exterior‐side C‐BN coated low‐E glass shows 2.9% energy savings compared to the interior‐side coated commercial low‐E glass. C‐BN would be a useful coating material for durable and energy‐efficient low‐E glass window technology.
