Wood Pulp-Based Optically Transparent Film: A Paradigm from Nanofibers to Nanostructured Fibers

Authors


Abstract

image

A low thermally expanded transparent film is developed by exploiting wood fibers that can be considered to be nanostructured fibers in which individual nanofibers do not significantly agglomerate and are oriented parallel to the fiber direction. It is thereby demonstrated that paper, used since ancient times, will be a next-generation optical material.
