An epoxy is a polymer that is often used for its binding and mechanical properties. It is formed by combining two monomers, which when reacted for a crosslinked structure that is very hard and tough. It is a thermosetting polymer, meaning that an irreversible exothermic reaction occurs when the two polymers are combined. Once the reaction has occurred the epoxy is, for all intents and purposes, permanently cured.
Epoxy has basically limitless applications and can be seen in fields ranging from aerospace to electronics. They are used as both electrical insulators when alone, and also electrical conductors when combined with silver. They are used architecturally as a material for walls, ceilings, and especially floors. They can be used as paint. They are also used for fastening bolts, and as castings. Moreover, epoxy as been used as a medium for art.
As stated earlier the light emitting effects coupled with an OFETs flexibility are of the most interest to current scientists. General Electric (GE) has invested in a project to create OFETs for roll to roll wallpaper to be used as indoor lighting. Also, clothing made with OFETs could be worn that display different images depending on what the wearer chooses. Furthermore, OFET paper with countless pixels that could light up when it is touched with a stylus could be a future means of communication, expression, and art. Finally, biological and chemical sensing, along with the medical field may be able to use OFETs as a type of 'electronic nose' as they are a coupling of chemical and electronic information.
