Abstract
"The effect of gamma irradiation on a solid-state cellulose nanofiber (SS-CNF) sheet was investigated. Changes in the physicochemical properties, such as the chemical structure, morphology, thermal stability and maximum stress, measured by tensile tests, were demonstrated after gamma irradiation under atmospheric conditions. The chemical structure investigated by using Fourier transform infrared spectroscopy and X-ray diffraction was unchanged after irradiation at 60 kGy; on the other hand, a dramatical change with yellowing was found after irradiation at 300 kGy, especially, a decrease in the thermal stability as well as the maximum stress of the CNF sheet was obvious. The physicochemical properties of CNF could be kept up to at least 60 kGy, with minor changes in the chemical structure, but were affected by further increases in the total dose of gamma irradiation."
