Fabrication and characteristics of cellulose nanofiber films

초록

Cellulose nanofiber (CNF) is an impressive bio resource mainly because of its high mechanical strength, stiffness and optical transparency, which is promising for eco-friendly structural materials. This paper presents the possibility of eco-friendly thin films made with CNF, which has strong, flexible, transparent and lightweight behaviors. The fabrication of thin CNF film and its properties are investigated. Fabrication is carried out by tape casting method to control thickness, followed by separation and drying. Its chemical structure and physical interaction were investigated using Fourier transform infra-red spectroscopy. Mechanical properties are investigated by a tensile test. 3 micron thick CNF film is successfully fabricated. The prepared CNF film is applicable for structural materials in space applications.
