Inorganic polymer

Definition

An inorganic polymer is a large molecule composed of repeated subunits that are primarily made up of inorganic elements, such as silicon, phosphorus, or boron, rather than carbon-based structures. These polymers exhibit unique properties that differentiate them from organic polymers, including high thermal stability and resistance to chemical degradation. The versatility of inorganic polymers allows for their application in various fields, particularly in materials science and nanotechnology.
