近年来，受到绿色轮胎的勃兴与欧盟轮胎标签法的推动，炭黑这一最古老的碳材料得到了快速发展，新品种大量涌现，占据了补强填料的统治地位，但其补强机理特别是有关的活性理论没有明显的突破。本项目以炭黑表面含氧基团与活性相关性为突破口，提出建立基于针尖化学及其力曲线的炭黑活性点的表征方法，拟依次增加炭黑表面的酸性含氧基团，然后让针尖与炭黑聚集体接近或远离，发生原子间吸附与排斥作用，记录吸/斥力循环作用过程（力曲线与摩擦力曲线），解析炭黑表面的力曲线突变点数据。创新之处在于采用高温人工干预的方法使炭黑表面活性点倍增，为有效探寻炭黑的活性基团与活性位置点提供条件，预期结果是确定炭黑表面羧基、酚羟基、酯基等基团在表面的位置，并与结合胶实验结果进行比较，判断其交联活性。研究旨在提出一种基于作用力的炭黑活性研究方法，指导螺旋纳米碳、石墨烯等新型炭材料活化改性，为研制新一代橡胶补强材料提供指导。

In recent years, due to the development of green tires and the promulgation of EU tyre-labeling laws, carbon blacks, the oldest carbon materials, make progress rapidly. With the emergence of plenty of new species, carbon blacks still occupies the dominant position in reinforcing fillers. However, the reinforcing mechanism of carbon blacks, especially the theory of surface activity, is still ambiguous. In this study, given the relationship between surface oxygen groups and activity of carbon blacks as a breakthrough point, we put forward the method, based on SPM tip chemistry and its force curve, to characterize the active points of carbon blacks. By increasing the acid oxygen groups in sequence, and controlling the distance between the probe tip and the surface of carbon black aggregates, we can record the adsorption or repulsion force between atoms with the force curve. At last, we use the turnning point data from the force curve to determine the existence of the activity points. The innovation of this project is that the method of high-temperature manual intervention used to make the changes of the surface active points of carbon black, which can provide convenience for exploring effectively the active groups and location points. The purpose of this project is to determine the positions of carboxyl, phenolic hydroxyl and ester groups on the surface of carbon blacks and then identify the activity of crosslinking. Generally, we can put forward a new method to study the activity of carbon blacks based on SPM tip force curve, which could guide the surface modification of new carbon materials such as fullerene, carbon nanotube and graphene. Therefore, when a new generation of carbon black reinforcing materials is developed under a balanced consideration of particle size, structure and activity, the reinforcing performance of green tires can be improved significantly.
