Inorganic Polymers

Abstract

The term "inorganic polymer" is used by many for inorganic materials such as silica and silicates, boron nitride, and the many other inorganic compounds that have twoand three-dimensional infinite crystal structures and consequently may be considered macromolecules. Even a crystal of sodium chloride may be considered a threedimensional polymer. But none of these "polymers" exhibit typical plastic behavior, perhaps because generally their structure is polymeric only in the solid state. We will limit our discussion of inorganic polymers to selected recent studies of linear chain-like giant molecules which are the type generally believed to offer potential for new plastic materials.Polymers should not contain any carbon in order to be termed inorganic polymers but in accordance with a recently agreed upon definition (1), we will consider inorganic polymers to be those that do not contain carbon in their backbones.Inorganic polymers are by no means a recent discovery. There are a number of inorganic substances-elements as well as compounds-that are polymeric and have elastomeric, or at least

Effects of substrates on the performance of optoelectronic devices: A review

“…It is usually found in dust particles and grains of sand as silicon dioxide (quartz) or on planets and planetoids as silicate making it the most abundant element after oxygen. The reflective nature of Silicon and the ability to control its charge carriers to obtain desired electrical properties are desirable properties in the optoelectronics industry (Asim et al, 2012;Iwata et al, 2001). The glass, on the other hand, is a thermally stable amorphous solid that has application in tableware optoelectronics and many others.…”
