#Toward reenpaper-thin, flexible electronics The rapid evolution of gadgets has brought us an impressive array of martproducts from phones to tablets, and now watches and glasses. But they still haven broken free from their rigid form. A new, environmentally-friendly paper that glows could lead to sustainable, roll up electronics. Credit: American Chemical Societynow scientists are reporting in the journal ACS Applied materials & Interfaces a new step toward bendable electronics. They have developed the first light-emitting, transparent and flexible paper out of environmentally friendly materials via a simple, suction-filtration method. Technology experts have predicted long the coming age of flexible electronics, and researchers have been working on multiple fronts to reach that goal. But many of the advances rely on petroleum-based plastics and toxic materials. Yu-Zhong Wang, Fei Song and colleagues wanted to seek a reenerway forward. The researchers developed a thin clear nanocellulose paper made out of wood flour and infused it with biocompatible quantum dots tiny, semiconducting crystals made out of zinc and selenium. The paper glowed at room temperature and could be rolled and unrolled without cracking. Source: AC c
