What is an ITO substrate?
Let’s break this down and start with the definition of a substrate. A substrate is a versatile term with various meanings depending on the context… ok, a bit ambiguous.
In biology, a substrate can refer to the environment where an organism like a plant, fungus, or animal lives, or it can be the material upon which an enzyme acts. In geology, a substrate is the surface of rocks or sediment where essential chemical and biological processes take place.
In chemistry, a substrate denotes a surface where chemical reactions can take place. In industries like coatings, it typically refers to the material upon which paints and coatings are applied. This can encompass a wide range of materials, including metal, wood, glass, plastic, fabric, rubber, paper, or leather.
Regardless of the field, the underlying principle of a substrate remains consistent – it provides a foundation for growth or processes to occur on a surface. Hopefully, that clears that part up a bit…
So, What Is An ITO Substrate?
It’s best to delve into ‘what is ITO’ first – ITO (Indium Tin Oxide) is a very special material that has two main characteristics. It is a clear compound allowing light to pass through and it is also electrically conductive, enabling the flow of electrical current on its surface.
Indium Tin Oxide can be deposited onto glass, plastic and PET film (and these materials are the ITO substrates! – we got there!). The combination of transparency on conductivity onto glass, plastics and thin films has really opened up the usage applications of ITO substrates…
