There are two types of modification: physical modification and chemical modification. Currently, chemical modification is commonly used. The most commonly used chemical modification is silane coupling agent as a surface modifier to modify white carbon black [6].
In addition, polymer graft modification is also a common method for modifying silica. The polymer used for modification usually chooses materials that have good compatibility with the reinforced matrix material, which helps improve nano Compatibility of silica with matrix material to achieve better reinforcement effect.
