Researchers at the University of Rochester have developed superhydrophobic tubes that exhibit exceptional buoyancy and stability, potentially paving the way for new types of floating infrastructure and renewable energy technologies. These tubes, despite being made of materials that would normally sink, remain afloat and can even support weight due to their unique surface properties.
University of Rochester research on Superhydrophobic Materials
Superhydrophobic materials are characterized by their extreme water repellency, causing water to bead up and roll off their surfaces. This phenomenon is achieved through a combination of surface roughness and low surface energy materials.The University of Rochester team created tubes coated with a superhydrophobic material that traps air, creating a cushion that allows the tubes to float even when punctured.
According to a study published in ACS Applied Materials & Interfaces, the tubes maintain buoyancy even after being punctured multiple times, demonstrating their robustness. This is because the trapped air prevents water from fully saturating the material.
National Science Foundation Funding and Applications for Floating Rafts
The research was supported in part by the National science Foundation (NSF), highlighting the agency’s interest in innovative materials science. The researchers demonstrated that these tubes can be connected to form rafts, offering a foundation for various applications, including ships, buoys, and floating platforms.
Laboratory tests involved tubes reaching lengths of nearly half a meter, and the design is scalable to support heavier loads. University of Rochester News reports that the team is exploring the potential for larger-scale structures.
Bill & Melinda Gates Foundation and Renewable Energy Potential
The Bill & Melinda Gates Foundation also contributed funding to this project, suggesting potential applications in areas relevant to global development. Beyond transportation and infrastructure, the team discovered that rafts constructed from these superhydrophobic tubes can capture energy from moving water.
This capability opens the door to generating electricity from waves, presenting a renewable energy solution. The researchers are investigating the efficiency of this energy capture method and its potential for practical implementation. As of January 31, 2026, there have been no further published reports detailing large-scale wave energy capture using this technology, but research continues at the University of Rochester.
This project also received support from URochester’s Goergen Institute for Data Science and Artificial Intelligence.
