Semiconducting nanomaterials with 3D network structures have high surface areas and lots of pores that make them excellent for applications involving adsorbing, separating and sensing.
However, simultaneously controlling the electrical properties and creating useful micro and macro-scale structures, while achieving excellent functionality and end-use versatility, remains challenging.
Osaka University researchers, in collaboration with the University of Tokyo, Kyushu University and Okayama University, have developed a nanocellulose paper semiconductor that provides both nano−micro−macro trans-scale designability of the 3D structures and wide tunability of the electrical properties.
Cellulose is a natural and easy to source material derived from wood. Cellulose nanofibres (nanocellulose) can be made into sheets of flexible nanocellulose paper (nanopaper) with dimensions like those of standard A4 paper. Nanopaper does not conduct an electric current; however...
