Ultra-fast and low-cost fabrication of transparent paper

Transparent paper is a kind of promising and environmentally friendly material.In this study,we show that transparent paper can be fabricated in an ultra-fast and low-cost way.This low-cost top-down method only takes three steps of cell separation,lignin removal,and cold pressing to obtain a high-quality transparent paper.The fabrication time is further reduced,and the resulted transparent paper shows high transparency up to 90.3%.The application as a substrate material for transparent and flexible electronic devices is demonstrated by emulating the printed circuit on the prepared transparent paper.This top-down method will greatly promote the market-oriented applications of transparent paper as an environment friendly material.
