- Abstract
The effects of different isolation methods on the separated bamboo parenchyma cells and fibers were investigated in terms of the microstructure, chemical composition, crystallinity, and thermal stability. The parenchyma cells and fibers isolated differently were characterized by scanning electron microscopy, Fourier-transforms infrared spectroscopy, chemical composition analysis, and thermogravimetric analysis. The results showed that mechanical isolation and steam explosion isolation destroyed the morphology of parenchyma cells and fibers more pronouncedly, while chemical isolation could obtain parenchyma cells and fibers with intact morphology and structure. The chemical isolation resulted in the significant removal of lignin from both the parenchyma cells and fibers, and their cellulose crystallinity was significantly increased, but the thermal stability was the lowest. The relative hemicellulose content in parenchyma cells and fibers separated by steam explosion was significantly decreased but the relative lignin content was increased.
