Microcrystalline cellulose (MCC) was first swollen and then hybridized with nano-ZnO to prepare MCC-ZnO hybrid composites using a microreactor technique. The microstructure of the ZnO particles was controlled and characterized. The results showed that the nano-ZnO particles had a Wurtzite structure and were successfully loaded on the surface of the MCC, and the ZnO morphologies could be shaped as spheres, rods or tubes by controlling the size of microreactor. The hybrid ratio of ZnO was approximately 20%. The MCC-ZnO hybrids were used in SSBR2557A/SiO compounds to replace portions of the silica. The results showed that MCC-ZnO compounds had improved processing and mechanical properties compared to the pure MCC sample. The dynamic mechanical analysis (DMA) indicated that MCC-ZnO compounds had higher wet-skid resistance and lower rolling resistance than the control samples. The interfacial bonding between the hybrids and rubber was also improved; the sizes of the hybrid composites decreased in situ during the rubber processing.
微晶纤维素 (MCC) 首先溶胀，然后与纳米 ZnO 杂交，使用微反应器技术制备 MCC-ZnO 杂化复合材料。控制和表征了 ZnO 颗粒的微观结构。结果表明，纳米 ZnO 颗粒具有纤锌矿结构，并成功负载在 MCC 的表面上，并且通过控制微反应器的尺寸，可以将 ZnO 形态塑造成球体、棒体或管体。杂化比约为 20%。将 MCC-ZnO 杂化物用于 SSBR2557A/SiO 化合物中，以替代部分二氧化硅。结果表明，与纯 MCC 样品相比，MCC-ZnO 杂化物具有改善的加工和机械性能。动态力学分析 (DMA) 表明，MCC-ZnO 化合物具有更高的湿滑阻力和更低的滚动阻力。杂化物和橡胶之间的界面结合也得到了改善；在橡胶加工过程中，杂化物复合材料的尺寸原位减小。
