Waste Plastics Become Molecular Sponges That Capture Water From Air
Discarded plastic packaging materials, old CDs, and even LEGO bricks can be transformed into materials that capture significant amounts of moisture from the air. Materials chemists Anastasiia Naryshkina, Paul Schweng and Robert Woodward at the University of Vienna have converted several types of plastic waste into water-attracting polymer networks that take up water even in dry climates and release it again under moderate heating, e.g. using sun…
From old CD cases, yoghurt cups and lego stones, materials can be produced that absorb water vapor even from relatively dry air. Researchers have succeeded in turning several types of plastic chemically into water-binding networks. In the laboratory test, one of these materials stored around 19 percent of its dry weight in water at 30 percent humidity. Vienna (Austria). When drinking water is scarce, water vapour can also [...] The article Plast…
