Researchers at Osaka Municipal University have developed a new method for collecting water from the air that requires significantly less energy than traditional methods. The use of a special copolymer solution allows moisture to be removed at a temperature of approximately 35°C instead of the usual 100°C. The study was published in the journal ACS ES&T Water (ACSW).
The new method is based on the use of copolymers of polyethylene glycol and polypropylene glycol. Polyethylene glycol is highly hydrophilic and effectively attracts water molecules, while polypropylene glycol has the opposite properties. The difference in properties creates a water transfer mechanism that breaks up water clumps and allows moisture to be released more quickly.
This discovery has tremendous potential to solve the problem of water supply in arid regions and regions with limited energy resources. According to Professor Masahide Takahashi, one of the authors of the study, technology can be useful in emergency situations, reducing greenhouse gas emissions and making more rational use of water resources.
The team plans to improve the technology and increase the overall efficiency of the system for practical use.
