bamboo (Phyllostachys edulis) residue was subjected to steam explosion treatment to produce superior fibers for binderless boards. Then, lignin was isolated from extract-free bamboo meal, steam exploded pulp, and binderless boards with characteristics being determined by thermo-gravimetry (TG), differential scanning calorimetry (DSC), and fourier transform infrared spectroscopy (FTTR). Results showed that (1) yields of lignin directly extracted with dioxane-water from steam exploded bamboo pulp (SEBPL) and binderless board (SEB-BL) were higher than that of milled bamboo lignin (MBL). Also, yield of sebbl was lower than SEBPL. (2) FTIR results showed cleavage of ester and ether bonds between lignin and p-coumaric acid during steam explosion treatment. (3) SEBBL showed two glass transitions at 115 °C and 200 t, while MBL gave one glass transitions at 155 展开▼
