The results indicated that transformation of the material induced by this treatment led to an increase in the contents of lignin and extractives, while a decrease in those of holocellulose and α-cellulose. Untreated samples were also set for comparison. X-ray photoelectron spectroscopy (XPS) and solid-state nuclear magnetic resonance (NMR) were used to characterize the changes in the chemical structure of components. The content changes of chemical composition and extractives after heat treatment were evaluated by chemical analysis. The objectives of this study were to investigate the effect of heat treatment on the chemical composition of poplar fibrosis veneers. Study on chemical constituent changes of fibrosis veneers during heat treatment is helpful to expand the application areas of scrimbers. The scrimber is composed of the special elementary unit called fibrosis veneers. ![]()
