High Barrier for Plastic Electronics - HIBPE

This collaborative R&D project focuses on meeting a large market opportunity (estimated >$1B global market by 2018) for developing a viable low-cost production route for clear, flexible, high and ultra-barrier, polymer-based substrates and encapsulant materials. These materials are intended for photovoltaic applications (including thin film inorganic, organic, and dye-sensitized (DSSC) solar cells), flexible organic solid-state lighting applications, and flexible lightweight robust display applications. The processes developed will be compatible with in-line process tools that are viable and scalable to commercial material widths (1m+) and production line speeds. The structure of the flexible barrier material will overcome market challenges such as cost, barrier performance, and sufficient barrier retention over time.

Feedback Overview:

The idea of developing low-cost, high-barrier flexible polymer substrates and encapsulant materials addresses a significant market need, particularly in the renewable energy and electronics sectors. To successfully reach product-market fit, it will be essential to validate the scalability of the production process and ensure that the barrier performance meets industry standards over time. Collaborating with industry partners and securing pilot projects can help demonstrate the feasibility and commercial viability of the technology.

What are the key technical challenges in developing high-barrier flexible polymer substrates?

The key technical challenges include achieving the desired barrier performance, ensuring flexibility and durability, and maintaining cost-effectiveness in production.

How can we ensure the scalability of the production process for commercial material widths?

Ensuring scalability requires developing in-line process tools that can handle large material widths and production speeds, as well as conducting pilot tests to validate the process.

What metrics should we use to measure the barrier retention over time?

Metrics should include water vapor transmission rate (WVTR), oxygen transmission rate (OTR), and mechanical durability tests to assess long-term performance.
