Abstract:
1. A method for providing a fire-retardant transparent panel comprising: providing a transparent matrix; providing a plurality of optically transparent, fire-retardant nanoparticles having a diameter less than the wavelength of visible light, and with an elongated shape; integrating the fire-retardant nanoparticles within the transparent matrix to form the fire-retardant transparent panel such that the fire-retardant nanoparticles remain in the transparent matrix in their original form, and such that the panel is substantially insensitive to a difference between a refractive index (RI) of the transparent matrix and a RI of the fire-retardant nanoparticles; and wherein said integrating the fire-retardant nanoparticles within a transparent matrix comprises integrating the fire-retardant nanoparticles within a transparent matrix in an orientation selected from the group consisting of random orientation, lined patterns, regular shaped patterns, irregular shaped patterns, overlapping patterns, weaved patterns, and combinations thereof.
