在开放式双辊磨机中制备炭黑（N-330）、有机改性的纳米粘土（NC）基三元颗粒纳米复合材料，所述三元颗粒纳米复合材料包含具有25摩尔%环氧基团的环氧化天然橡胶基质（ENR-25）。分别使用流变分析、动态力学分析（DMA）、力学性能评价、热重分析（TGA）、高分辨率透射电子显微镜（HR-TEM）进行固化特性、动态力学、拉伸、热和形态特性的研究，以导出复合材料内部开发的纳米结构、交联密度、从那里获得的性能。在各种结果之间获得了令人满意的相关性水平，这表明在ENR-25基质内形成了由N-330和NC组成的“纳米单元”。为了优化纳米结构，制备含有NC和N-330的各种组合的基于ENR的化合物。对这些复合材料进行了全面系统的结构-性能分析。推导出ENR-25基质中N-330和NC的最佳化学计量组合（N-330和纳米粘土的重量%比= 20：15），这表明一种填料对另一种填料的协同效应，最终反映在其动态力学和拉伸性能中。Polym.比较器：31：835-846，2010.

Carbon black (N-330), organically modified nanoclay (NC) based ternary, particulate nanocomposites comprising of epoxidized natural rubber matrix having 25 mol% of epoxy group (ENR-25) were prepared in an open two-roll mill. Investigations of cure characteristics, dynamic mechanical, tensile, thermal, and morphological characteristics were conducted using Rheometric analysis, Dynamic Mechanical Analysis (DMA), mechanical property evaluation, Thermo-gravimetric analysis (TGA), High Resolution Transmission Electron Microscopy (HR-TEM), respectively, to derive the interrelation among the developed nanostructures inside the composite, crosslinking density, performance properties obtained there from. A satisfactory level of correlation was obtained among various results, which indicated the formation of "nanounit" comprising of N-330 and NC inside ENR-25 matrix. To optimize the nanostructures, ENR based compounds containing various combinations of NC and N-330 was prepared. Thorough and systematic structure-property analyses were performed on those composites. Optimum stoichiometric combination of N-330 and NC inside the ENR-25 matrix was derived (ratio of N-330 and nanoclay in wt% = 20:15), which showed synergistic effect of one filler upon another that was ultimately reflected in their dynamic mechanical and tensile properties.
