Abstract

Abstract:

Dynamic mechanical analysis (DMA) could be used to evaluate the effect of softening treatment with heat and water.The results of DMA showed that storage modulus (E′) of softening treatment bamboo at 120 ℃ for 30 min was apparently decreased compared with that of no softening treatment bamboo. The storage modulus (E′) of bamboo at 40 ℃ after softening treatment at 120 ℃ for 30 min reduced 60.4% compared with that of no softening treatment bamboo. That is to say that the effect of softening treatment at high temperature was obvious. Glass transition temperature (T_g) of no softening treatment bamboo was 119.8 ℃, while glass transition temperature (T_g) of softening treatment bamboo at 120 ℃ for 30 min was 88.4 ℃, T_g of softening treatment bamboo at 120 ℃ for 30 min decreased 26.2% compared with that of no softening treatment bamboo.

Key words: bamboo, softening treatment, glass transition temperature (T_g), dynamic mechanical analysis (DMA)
