9/15/2023 0 Comments Example translucent materialsMany substances are selective in their absorption of white light frequencies. Many such substances have a chemical composition which includes what are referred to as absorption centers. Materials which do not transmit light are called opaque. Absence of structural defects (voids, cracks, etc.) and molecular structure of most liquids are mostly responsible for excellent optical transmission. Many liquids and aqueous solutions are highly transparent. Some materials, such as plate glass and clean water, transmit much of the light that falls on them and reflect little of it such materials are called optically transparent. Photons interact with an object by some combination of reflection, absorption and transmission. These interactions depend on the wavelength of the light and the nature of the material. When light encounters a material, it can interact with it in several different ways. Other categories of visual appearance, related to the perception of regular or diffuse reflection and transmission of light, have been organized under the concept of cesia in an order system with three variables, including transparency, translucency and opacity among the involved aspects. The opposite property of translucency is opacity. Transparent materials appear clear, with the overall appearance of one color, or any combination leading up to a brilliant spectrum of every color. A transparent material is made up of components with a uniform index of refraction. In other words, a translucent material is made up of components with different indices of refraction. Translucency (also called translucence or translucidity) allows light to pass through, but does not necessarily (again, on the macroscopic scale) follow Snell's law the photons can be scattered at either of the two interfaces, or internally, where there is a change in index of refraction. On a macroscopic scale (one in which the dimensions are much larger than the wavelengths of the photons in question), the photons can be said to follow Snell's law. In the field of optics, transparency (also called pellucidity or diaphaneity) is the physical property of allowing light to pass through the material without appreciable scattering of light. The use of polycarbonate panels also provided visual depth to an otherwise two-toned environment, acting simultaneously as a transmitter of light, a partition, and an advantageous aesthetic attribute.Dichroic filters are created using optically transparent materials. Facilitated in part through the use of semi-transparent polycarbonate panels, this material choice afforded the privacy needed for certain spaces while still ensuring that the brightness achieved by the abundant windows and white walls did not go to waste. Blends of different types of plastics can also produce more tailored properties: polycarbonate/ABS blends, for example, combine polycarbonate’s impact and heat resistance with the ductility of ABS.īelow, we list 8 great examples of polycarbonate use indoors, each taking advantage of polycarbonate’s unique material properties in different ways.Ĭlad with white surfaces, soaring skylights, and interspersed with red accents, this 2018 Beijing office distributes light throughout, even in enclosed spaces. For example, benzotriazole stabilizers help protect polycarbonate from UV degradation. However, manufacturers can also inject additives that adapt standard polycarbonate to specific needs. Most are differentiated by the amount of glass fiber contained or by variance in melt flow. For example, recycled polycarbonate can be chemically reacted with phenol in a recycling plant to produce monomers that can be turned back into plastic.īesides specifications of color, shape, translucency, and texture, there exist several materially distinct types of polycarbonate. Finally, it is easily recyclable because it liquefies rather than burning, making it at least more environmentally friendly than other thermoset plastics. Like glass, it is a natural UV filter and can be colored or tinted for translucency, yet it is also prized for its flexibility, allowing it to be shaped into any size or shape. However, it is also lighter and stronger than glass and tougher than other similar plastics such as acrylic, polystyrene, ABS, or nylon, making it a good choice for designers seeking durable, impact and fire resistant materials that still transmit light. In its raw form, polycarbonate is completely transparent, transmitting light with nearly the same efficacy as glass. Polycarbonate, a type of lightweight, durable thermoplastic, is an excellent medium for both functions. At the same time, adding partitions or other delineations of internal space can help organize flow, circulation, and visibility. Diversifying the materials of an interior space can greatly improve its depth and visual interest.
