Due to its ecological benefits, bamboo is considered as attractive material. Recently, conventional bamboo modification in industry consumes time and chemicals. Supercritical fluid technology contributes to overcome these disadvantages. This process was performed in a batch impregnation with a statistical method. In this study, durability tests over a period of 32 weeks confirm that acetylated (un)-extracted bamboos regarded as durable material with mass loss ratio median (X) of 0.24-0.25. Additional the results of water sorption isotherm and the fibre saturation points are illustrated, as well as the crystallinity index. (C) 2014 The Authors, Published by Elsevier B.V.
