Overview
- In a peer-reviewed study, the paint-like layer reflected up to 97% of sunlight and radiated heat to trigger dew formation without energy input.
- Outdoor testing on the Sydney Nanoscience Hub roof captured dew during roughly 32% of the year, indicating collection is feasible between rain events.
- The nanoengineered PVDF‑HFP coating achieves high reflectivity through microscopic pores rather than UV-absorbing pigments, reducing glare and avoiding common degradation pathways.
- Performance remained stable with no observed degradation over six months under harsh sun, supporting short-term durability claims.
- The University of Sydney has licensed the technology to Dewpoint Innovations, which is developing a water-based formulation for roller or sprayer application, with example yields of about 4.7 liters per day from a 12 m² roof section under optimal conditions.
