Traditional white carbon black has been limited in its application due to the aggregation of surface hydroxyl groups in organic phases. Nowadays, scientists have achieved precise modification through "molecular surgery" technology: using atomic layer deposition (ALD) to coat a single layer of alumina on the surface of white carbon black, retaining its high activity and endowing it with hydrophobicity; Alternatively, by clicking on the chemically grafted fluorocarbon chain, it can form a dynamic self-healing film in lubricating oil, reducing the friction coefficient to below 0.01. More cutting-edge research is exploring the immobilization of biological enzymes on modified white carbon black surfaces to construct intelligent catalysts for degradable plastics. These breakthroughs in surface engineering technology have transformed white carbon black from a "passive filler" to a "functional regulator", opening up a new dimension in materials science.
