Partnering opportunity

A Finnish university is looking for licensing partners for their multilayer coated paper substrate for printed electronics

Summary

A Finnish university is looking for licensees like specialty paper or printed electronics manufacturers for a multilayer coated paper substrate suitable for printed functional devices. The substrate can be recycled, and the raw materials used are widely available bulk chemicals for paper production and coating. The paper can be produced by roll-to-roll manufacturing and its properties can be readily tuned to suit the selected printing application and to achieve a desired function.

Partner expertise sought

The university is looking for companies interested incommercial exploitation of the technology and acquiring the IP rights of the granted patents. Potential partners could be for example: -specialty paper manufacturers -manufacturers of printed electronics with possibilities to outsource the production to a suitable paper production facility. -companies operating in bio- and chemical sensors, microfluidics, smart packaging, logistics management and tracking, single use electronic circuits, devices and displays

Description

A Finnish university has developed a multilayer coated paper substrate for printed functional devices. The invention is based on ca. 10 years of intense research activities, and the research group has collaborated tightly with industrial partners during its development. The paper substrate has been produced in pilot trials in industrial paper-making facilities and successfully tested in several proof-of-concept applications including for example a low-voltage organic transistor, an electrochromic pixel, oxygen sensor, hydrogen sulphide sensor and an ion-selective electrode. The paper substrate comprises of a multilayer structure including a top coating, barrier layer, smoothing layer, pre-coating and basepaper. The substrate can be recycled, and the paper is therefore suited for "one-time" or "throwaway" applications. The raw materials used are widely available bulk chemicals for paper production and coating. The concept enables the use in a wide range of printing and coating methods. The surface properties of the substrate can be readily tuned or new ones added to achieve a desired function. The versatile applicability of the developed paper substrate has been demonstrated with several proof-of-concept devices including transistors, ion-selective electrodes and chemical sensors. The invention has granted patents in China and in nine European countries (GB, FR, DE, CH, FI, NL, SE, AT, BE). Potential commercial application areas include for example bio- and chemical sensors, microfluidics, smart packaging, logistics management and tracking, single use electronic circuits, devices and displays. The university is looking for licensees interested in commercial exploitation of the technology and aqcuiring the IP rights for the technology. Potential partners could be for example specialty paper manufacturers, or manufacturers of printed electronics with possibilities to outsource the production to a suitable paper production facility.

Advantages and innovations

The advantages of the paper substrate with regard to its manufacturing include the possibility to produce it from widely available paper production and printing chemicals by roll-to-roll manufacturing. The properties of the substrate are advantageous in comparison to the available solutions due to its versatile functionality, its excellent barrier properties against liquids and its flexibility. The substrate is also recyclable, and it can also be considered to be an alternative to plastic substrates for printed electronics

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
