Oxygen Barrier Coatings or Encapsulation Technologies (Ref : 11 US 87GA 3KK3 )

Technology Request

Description :

A new organic material has been developed that improves the optical performance of lenses made from oxygen permeable polymer or ceramic materials. This new micron size organic material is added to the lens material prior to the shaping process and is evenly distributed throughout the finished lens. Unfortunately, the organic material degrades rapidly when exposed to ambient oxygen. Therefore, all lens surfaces must be coated with an oxygen barrier. Alternatively, the micron sized particles of organic material can be encapsulated in an oxygen impermeable substance that can be added prior to shaping the lens. All coatings and encapsulating materials must have both good light transmission as well as oxygen barrier properties.

Potential solutions might include, but are not limited to :

  • Wet-chemical oxygen barrier coatings
  • Sol-gel oxygen barrier coatings/processes
  • Vacuum deposited oxygen barrier coatings/processes
  • Materials that can encapsulate micron sized organic substances.

The following approaches are not of interest :

  • Materials and/or processes not REACH/RoHS compliant
  • “Vacuum envelope” solutions.

Technical Specifications / Specific technical requirements of the request

The lenses are made in various shapes depending on the application. Therefore, the oxygen protection technology for the organic additive must be compatible with flat or curved substrates.

The coating or encapsulation technology must :

* Have extremely low permeability for ambient oxygen
* Have high optical transmission for visible light (>95%), colorless
* Be thermally stable up to 150C° (no change in optical and mechanical properties)
* Have maximal process temperatures of 350C° for use with ceramic lenses
* Have maximal process temperatures of 130C° for use with polymer lenses
* Be suitable for mass producing lenses up to 6X6cm @ >200 lenses/hour
* Be cost-effective.

Further Information (Technical Details Concerning the Profile)

The respondent should start by submitting a written response briefly describing the technical approach and providing information on technology performance, background, and description of the responding team and its related experience.

The response will be evaluated according to the following criteria :

* Overall scientific and technical merit of the proposed approach.
* Approach to proof of concept and performance.
* Potential for proprietary position (i.e. novel or protectable technology).
* Economic potential of the concept.
* The respondent’s capabilities and related experience.

* Realism of the proposed plan and cost estimates. Some items that will be especially important to include :

- Ability to adapt technology to polymer or ceramic lenses - Maturity and production readiness of the technology - Manufacturing capabilities - Description of the advantages of the proposed solution compared to current methods - Relevant authored patents, patent applications - Plan for meeting any unmet requirements.


Responses from companies (large or small, startups, etc.), hospital or academic researchers, contract research institutes, pharmacologists, nutritionists, medicinal chemists, drug formulators, biochemists, physiologists, alternative or traditional medicine providers, etc., from around the world are all welcome.


Phase I – Proof of principle : the company will evaluate the technical feasibility of proposed solution – 6 months

Phase II – Proof of concept prototype : the company will review the optical as well as lifetime performance data (accelerated life-time testing) – 6 months

Phase III – Commercial development : Respondent will demonstrate the feasibility of manufacturing the proposed solution (small scale pilot-production). The detailed scope of this phase will be determined after successful completion of phase II


Demonstrating successful proof of concept prototype (incl. life-time results) in phase II and demonstrate reasonable likelihood for cost effective scale up.

Note that this profile requires a convincing solution proposal. Please contact your local EEN to get the Response template and find more information on the specific process here : ?action=processFlow
