Abstract
Bamboo fibers (BFs) coated with titanium urushiol (BFTiU) was prepared by in situ reaction. Effects of activation time, urushiol concentration, reaction time and butyl titanate concentration etc on the coating ratio of BFTiU were investigated. On the other hand, the BFTiU was characterized by FTIR measurements, scanning electron microscope, thermo gravimetric analysis and differential scanning calorimetry. The results showed that titanium urushiol compound was coated on the BFs by coordination reaction and the coating ratio of BFTiU reached 35% at the optimal preparation condition. It also could be found that BFTiU possessed better heat resistant properties than BFs. Due to titanium urushiol coated on BFs, the elongation at break, the maximum deflection and the bending strength of BFTiU/PP composites were 33%, 30 % and 10% higher than those of BP/PP composites respectively. Particularly, the tensile strength of BFTiU/PP composites was better than that of BP/PP composites at the presence of 70% BFTiU.
