碳纳米纤维（CNFs）作为新材料一直是材料研究的重点，同时被广泛应用于橡胶复合材料的加工。为了解决CNFs易团聚的问题，现有的方法主要是对CNFs进行化学改性（加工工艺复杂），掺入碳纳米管等填料（材料昂贵，生产成本比高）。在本研究中，我们结合经济性和加工方法，使用裂解炭黑 (CBp) 和 CNF 进行共混制备橡胶复合材料，以解决填料团聚问题。发现CBp和CNFs产生协同效应，两者相互隔离，相互接触，在复合材料内部形成更完整的填料网络。通过协同效应，填料在橡胶中的分散性变好，复合材料的性能大大提高。与传统的填料共混相比，更经济，可在很大程度上节省生产成本；与化学改性相比，工艺简单，节省生产时间。通过大量使用CBp可以促进橡胶制品的回收利用，具有一定的环保效果。本研究为聚合物复合材料加工提供了新思路，后期还需要更多的实验来验证该方法的可行性。通过大量使用CBp可以促进橡胶制品的回收利用，具有一定的环保效果。本研究为聚合物复合材料加工提供了新思路，后期还需要更多的实验来验证该方法的可行性。通过大量使用CBp可以促进橡胶制品的回收利用，具有一定的环保效果。本研究为聚合物复合材料加工提供了新思路，后期还需要更多的实验来验证该方法的可行性。

Effect of synergy between pyrolysis carbon black and carbon nanofibers on composite properties

Carbon nanofibers (CNFs) as new materials have been the focus of materials research, while being widely used in the processing of rubber composites. To solve the problem that CNFs are easy to agglomerate, the existing methods are mainly chemical modification of CNFs (complicated processing process), blending with fillers such as carbon nanotube (expensive material and high production cost ratio). In this study, we integrated the economics and processing methods, and used pyrolysis carbon black (CBp) and CNFs for blending to prepare rubber composites to solve the filler agglomeration problem. It was found that CBp and CNFs produce a synergistic effect, and the two are isolated from each other and in contact with each other, forming a more complete filler network inside the composite. Through the synergistic effect, the filler dispersion in the rubber becomes better and the performance of the composite is greatly improved. Compared with traditional filler blending, it is more economical and can save production costs to a great extent; compared with chemical modification, the process is simple and saves production time. The recycling of rubber products can be promoted through the mass use of CBp, which has a certain environmental protection effect. This study provides new ideas for polymer composite processing, and more experiments are needed later to verify the feasibility of this method.
