Phase Change Foam Sustains Solar Desalination Through Low Light And Darkness

Tokyo, Japan (SPX) May 01, 2026

Researchers from Ocean University of China and Huzhou University have developed a phase-change photothermal foam that continues to produce freshwater after sunlight fades, addressing one of the core limitations of solar-driven desalination technology.

The material, designated PPy-CS/PF@DDA, is constructed by confining dodecylamine inside a polypyrrole-coated chitosan/phenolic resin foam. P
