Ever Ancient Ever New - Cellulose as The Material Platform for Sustainable Flexible Devices

Cellulose, the main component in cotton, features a naturally occurred hierarchical structure down to the ångström scale, providing a scaffold with multiscale interspace and abundant functional groups. In this talk, I will talk about our work using cellulose as the material platform for flexible ionic and electronic devices. We will focus on the design principles as well as the application scenarios in energy generation, conversion and sensing.
