[nanoPost] Ultra-violet curable organic semiconductors

Company UK

The company develops new instant inkjet printable ultra-violet (UV) curable organic semiconductors. The company  offers intellectual property licences to customers researching and/or manufacturing their own products.

For bespoke, low/medium applications the companys’ organic nanotechnology is cost effective, requires a simple fabrication process and retains all of its volume during curing. The companys’ technology is 100% polymer based, can be inkjet printed on flexible substrates, instantly cures when exposed to ultra-violet light and does not require an inert printing environment.

The companys’ UV curable nanotechnology draws from three established technologies; organic semiconductors, UV curable resin chemistry and UV curing technology.

Organic semiconductors are built up in layered stages. The layers are inkjet printed one upon the other to form a complete single component:

- Anode. Conductive electron path to get energy to the device

- Semiconductor layers to emit light

- Cathode. Conductive electron path to get energy away from the device

Encapsulation to protect against water ingress and contamination
The companys’ UV curable formulations are blended to maintain the balance between effective curing, whilst retaining the properties of organic semiconductors. There are four main components to UV curable products.

UV sources are of three types:  high-pressure arc lamps, lasers, or LEDs. The spectral output waveform/power density initiates polymerisation for an instant cure.

Digital inkjet printers are generally one of two types, flatbed, or roll-to-roll. The choice of which to use is determined by the product’s application. Flatbed printers are used to produce rigid/flexible prints for substrates up to 3m2, whilst roll-to-roll create flexible prints.

The company end product is a licence for flexible organic device’s which can be manufactured to a given customers unique requirements. The company provides the licence to manufacture and the knowledge to provide a complete market-ready package.
