WASHINGTON, Feb 17 (Xinhua): Chinese scientists have developed a large-scale transparent smart window that can change light intensity while effectively capturing the particulate matter in smog, said a study published on Saturday in the journal iScience.

The study described a simple solution-based process to fabricate large-area flexible transparent windows with Ag-nylon electrodes for high-efficiency PM2.5 capture.

It takes only 20 minutes to fabricate 7.5 square metres of Ag-nylon flexible transparent windows showing an optical transmittance of over 86 per cent, according to the group of scientists led by Yu Shuhong from the University of Science and Technology of China (USTC).

The Ag-nylon mesh can not only change the indoor light intensity, but also purify indoor air as a high-efficiency PM2.5 filter.
