| 中文摘要: |
| 采用乳液法制备天然胶乳/有机粘土纳米复合材料（NRLCNs），研究NRLCNs的结构、试样厚度和粘土用量对NRLCNs拉伸诱导结晶行为的影响。结果表明：NRLCNs为插层型结构；试样厚度相同时，有机粘土用量为3份的NRLCNs物理性能最优；有机粘土用量相同时，试样厚度较小的NRLCNs物理性能较优；随着拉伸强度的增大，NRLCNs的定伸应力逐渐增大，当达到临界应变值时，定伸应力迅速增大，产生拉伸诱导结晶行为，试样厚度较小的NRLCNs易产生拉伸诱导结晶行为。 |

| Natural latex/organic clay（NRLCNs）nanocomposites were prepared by emulsion polymerization. The effects of NRLCNs"" structure，thickness of samples and clay content on the strain-induced crystallization behavior of composites were investigated.The results showed that，NRLCNs were intercalated structure.When the thickness of samples was the same，the physical properties of NRLCNs with organic clay content of 3 phr were the best.When the amount of organic clay was the same，the physical properties of NRLCNs with smaller thickness of samples were better.With the increase of tensile strength，the modulus of NRLCNs increased gradually.When the critical strain value was reached，the modulus increased rapidly，resulting in the strain-induced crystallization behavior The NRLCNs with smaller sample thickness are prone to the strain-induced crystallization behavior. |
