Abstract

Cellulose nanofibre sheet materials are of great interest in various applications because of their excellent properties, but are difficult to prepare rapidly and as large sheets. This paper describes a quick preparation procedure for preparing optically transparent, flat and smooth nanofibre sheets, which is much quicker than existing methods. Low permeability, optical transparency, high strength and high density show that nanofibres were well dispersed. The preparation time for the nanofibre sheet produced here was 10 min whereas the preparation times reported in literature is above 1 h. The decrease in sheet preparation time suggests that this method can be used for commercial applications.
