(a) Opaque cellulosic paper made of wood fibers. (b) Transparent hybrid paper consisting of two layers: the bottom layer is made of CNFs and the top layer is produced by saturating CNFs into the pores among the network of wood fibers. The width of the wood fiber and CNFs is 10–50 mm and 5–30 nm, respectively. (c) Image of the designed all-cellulose hybrid transparent paper with thickness of 70 m [23].
