| Abstract: | Bamboo cellulose micro-powder(BCMP)was obtained by the thermo-chemistry selective liquefaction of bamboo powder,then the surface of BCMP was etherified through their hydroxyl groups with maleic anhydride(MAH).The effect of treated temperature and time on the esterification was investigated.The results showed that the BCMP with higher degree of esterification(16.2%)and lower hydroxyl of 15.6 mgKOH/g were obtained finally at the temperature up to 140℃ for 4 h.Compared to unmodified BCMP,the modified BCMP had rough surface,similar crystalline properties,and excellent UV absorption properties.The tensile strength,bending strength of PE-HD/modified BCMP composites increased substantially,while the water-swellable stability of the composites was also significant improved as well. |
