PTFE Membrane - A New Material for Radiant Cooling

To meet the challenge of energy-intensive summer cooling, UNM is exploring the frontiers of polytetrafluoroethylene (PTFE) membranes for radiant cooling! We have made significant progress in this innovative material, unlocking the potential for cooling without additional energy consumption and practicing green and low-carbon development.

01. Innovative R&D: Decoding PTFE's “cooling code”

Radiative cooling, which utilizes a specific band (8-13μm atmospheric window) to radiate heat directly into cold space, is an ideal zero-energy cooling pathway. UNM's R&D team is deeply committed to PTFE material science and has made key breakthroughs in research on radiative cooling applications:

Superior Photothermal Management Potential: The PTFE material system under development has demonstrated excellent solar reflectance and efficient infrared radiation and emission trends, providing an important material foundation for efficient passive cooling.

Core R&D Strengths: Focus on formulation design, innovation of micro and nanostructures (e.g., porous ePTFE), weathering mechanisms and surface properties to continuously optimize its radiative cooling performance.

02. R&D foundation building: building a core technology platform

UNM is actively building R&D capacity of PTFE membranes for radiative cooling:

In-depth exploration of the performance of monolayer membranes, multilayer structures and functionalized systems.
