Monodisperse mesoporous carbon spheres (MCS) were synthesized and their potential applications in ethylene propylene diene monomer (EPDM) foam were evaluated. The obtained MCS exhibited a high specific surface area ranging from 621-to 735 m/g along with large pore sizes. It was observed that the incorporation of MCS into EPDM foam rubber significantly enhances its mechanical properties. The prepared MCS-40 rubber composites exhibit the highest tear strength of 210 N/m and tensile strength of 132.72 kPa, surpassing those of other samples. The enhancement mechanism was further investigated by employing computer simulation technology. The pores within the MCS allowed for the infiltration of EPDM molecular chains, thereby strengthening the interaction forces between the filler and matrix. Moreover, a higher specific surface area resulted in greater adsorption of molecular chains onto the surface of these carbon spheres. This research offers novel insights for understanding the enhancement mechanism of monodisperse mesoporous particles/polymer composites (MCS/EPDM) and highlights their potential application in high-performance rubber composites.
合成了单分散介孔碳球（MCS），并评估了它们在三元乙丙橡胶（EPDM）泡沫中的潜在应用。所获得的MCS具有621至735 m²/g的高比表面积以及大孔径。观察到将MCS掺入EPDM泡沫橡胶中可显著提高其机械性能。制备的MCS-40橡胶复合材料表现出最高的撕裂强度210 N/m和拉伸强度132.72 kPa，超过了其他样品。通过采用计算机模拟技术进一步研究了增强机理。MCS中的孔隙允许EPDM分子链渗透，从而增强了填料与基体之间的相互作用力。此外，较高的比表面积导致分子链在这些碳球表面上的吸附量更大。这项研究为理解单分散介孔颗粒/聚合物复合材料（MCS/EPDM）的增强机理提供了新的见解，并突出了它们在高性能橡胶复合材料中的潜在应用。
