| 中文摘要: |
| 研究硫黄用量对杜仲橡胶形状记忆材料性能的影响。结果表明：随着硫黄用量的增大，胶料的ML变化不大，MH增大，t90先缩短后延长；硫化胶的交联密度总体呈增大趋势，定伸应力和拉伸强度先减小后增大，热刺激响应回复温度呈减小趋势，最终形变回复率先增大后减小；动态力学性能测试发现，存在多相转变峰；当硫黄用量为1份时，硫化胶的物理性能和热致形状记忆性能最佳。 |
| 英文摘要: |
| The effect of addition level of sulfur on the shape memory property of eucommia ulmoides gum was investigated. When the addition level of sulfur increased，the ML of the compound changed little， the MH increased， and the t90 was shortened at first and then extended.Meanwhile，the crosslink density of the vulcanizates tended to increase，the modulus and tensile strength decreased at first and then increased，the thermal stimulation response temperature tended to decrease，and the final deformation recovery rate increased at first and then decreased.When the addition level of sulfur was 1 phr，the physical properties and thermal induced shape memory property of the vulcanizates were the best. |
