摘　　要：采用共凝沉法制备了纳米晶纤维素/天然橡胶(NCC/NR)复合材料。对复合材料的微观结构、物理机械性能、动态力学性能、热稳定性分析结果表明,纳米晶纤维素在天然橡胶中分散均匀,对天然橡胶有较好的补强作用,复合材料的储能模量提高,损耗因子下降,但对天然橡胶的热稳定性影响不大。Nano-crystalline cellulose/natural rubber （NCC/NR） composites were prepared by coagulating the NCC suspension and the NR Latex, and the micro-structure, physical mechanical properties, dynamic mechanical properties, thermal stability of the composites were investigated. The result showed that the NCC particles were dispersed uniformly in natural rubber matrix and showed a good reinforcing effect on NR, and that the E＇ of the composites was increased while the tanδ reduced. However, no change was found in the thermal stability of natural rubber.
