A consortium of international physicists has engineered a novel coating designed to grant metal pipes buoyancy. This method allows for the treatment of both the external and internal surfaces of piping, imbuing them with superhydrophobic characteristics. The incorporation of air pockets within the coating enables these pipes to remain afloat on water, as reported by the University of Rochester’s press office.
Tests conducted under harsh conditions demonstrated that the buoyant effect persists for up to seven days. Furthermore, the coating maintains its efficacy even when subjected to damage. The researchers express confidence that this technology is scalable for fabricating stable floating structures.
The foundation of this innovation draws parallels with the structural properties observed in lotus leaves. Utilizing laser pulses, the scientists etched microscopic patterns of peaks and depressions onto the aluminum surface, a process applicable to curved sections without compromising performance.
Previously, the team had succeeded in constructing miniature rafts from coated aluminum discs. This prior endeavor motivated their subsequent development of half-meter floating pipes. Assessments confirmed the coating provides stability even when the pipe is fully submerged vertically and exposed to significant wave action. An internal partition also contributes to the overall buoyancy.
This recently developed technique holds promise across numerous sectors. Its utility extends beyond the assembly of floating architecture; it is also applicable in the energy sector for harnessing wave power conversion. Consequently, this advances the horizons for engineers focused on devising effective systems in marine engineering and renewable energy fields.
