L2M – ThermaSwitch: Passive Films for Adaptive Heat Management

This project aims to develop and validate a low-cost, energy-efficient film made from common or recycled plastics that can passively manage heat without using electricity or fuel. By microstructuring the surface of materials like polyethylene and polymethylpentene (TPX), we create thin, flexible films that can either retain or release heat depending on their arrangement. When two films are pressed together, they allow thermal radiation to pass through; when separated, they scatter it, creating a switchable system that mimics smart windows—but without electronics or coatings.

The research will focus on refining the production process using scalable mold-based manufacturing techniques and testing the films in real-world environments such as buildings or greenhouses. The system can reduce heating and cooling needs by passively managing thermal energy, helping reduce operational costs and carbon emissions. It offers a competitive advantage over existing insulation and reflective materials by being adaptable, affordable, and easy to integrate into current construction or agricultural practices.

The partner organization will benefit by gaining early access to a versatile and sustainable technology that aligns with energy efficiency goals and carbon reduction targets. This innovation supports their role in advancing clean technologies and can lead to new product lines, pilot projects, and potential commercialization. By participating in the development phase, the partner helps shape a product with real market relevance, strengthening their position in Alberta’s and Canada’s growing clean-tech economy.
