Abstract

Mesoporous structures made of cellulose nanocrystals (CNCs) and their self-assembly into films are of great interest not only due to their abundancy and sustainability but also due to their ease of...

Highlights

  • The use of natural materials such as cellulose in electronic devices has shown to be of monumental importance to open up paths to cheap and future-orientated electronic and optoelectronic devices.[1,2] The attention gained for its integration as an active or passive component into a big variety of devices can be mainly attributed to its abundance and mass production possibilities, making it one of the cheapest alternatives to replace conventional plastics in the industry.[3,4] challenges for the integration of conventional paper into optoelectronic devices, such as surface roughness, porosity and opaqueness, remain.[5]

  • The cellulose nanocrystals (CNCs) were obtained by chemically breaking down microcrystalline cellulose into high aspect ratio nanorods, which remain stabilized in aqueous suspension due to sulfate groups on the CNCs’ surface.[22,23]

  • We report on the integration of ion infiltrated twisted mesoporous photonic dried droplets based on cellulose nanocrystals (CNCs) into semiconductor devices and inverter circuits

Summary

Introduction

The use of natural materials such as cellulose in electronic devices has shown to be of monumental importance to open up paths to cheap and future-orientated electronic and optoelectronic devices.[1,2] The attention gained for its integration as an active or passive component into a big variety of devices can be mainly attributed to its abundance and mass production possibilities, making it one of the cheapest alternatives to replace conventional plastics in the industry.[3,4] challenges for the integration of conventional paper into optoelectronic devices, such as surface roughness, porosity and opaqueness, remain.[5]. They are found for instance in the characteristic blue wings of the morpho butterfly, certain types of scarab beetles, birds, or even seashells, and they offer potential for their use in highly engineered optical systems.[16]
