| Abstract: |
| In this study, lignophenols were separated from bamboo (Sinocalamus Affinis) using phase separation system.Besides its structure features were analyzed, the resulted lignophenols were used to impregnate pulp fibers to form paper sheets composites.The results showed that the weight-average molecular weight of bamboo lignophenols (Lps) was 2884, which easily dissolved in common organic solvent such as acetone, ethanol and tetrahydrofuran, etc., dispersion coefficient of the molecular weight was 1.60.The absorption amount (12%) of Lps （the concentration of Lps acetone solution was 9.13 g/L） in the paper made of non-fibrillated eucalyptus pulp fibers was slightly higher than that (10%) in the paper made of fibrillated eucalyptus pulp fibers at the same impregnating time.The physical properties of tensile strength, elongation, bursting, tearing etc of the paper impregnated with Lps were significantly improved, more significant improvement of physical strength was founded in the paper made of fluffy short pulp fibers.It indicated that the amount of absorbed Lps was as same important as the properties of pulp fibers.This hinted that it was necessary to adjust the properties of both Lps and pulp fibers to get the best mechanical characteristics of composites. |
