NOVELTY - High-flux hydroxylation of inorganic filler based on low temperature plasma involves spreading the filler to be treated (3) on the conveyor belt (1), using a roller-to-roller device to drive the conveyor belt to move, so that the flattened filler to be treated is moved to the plasma zone. The controller sends a control signal to the power supply under the processing temperature T, so that the power supply discharges the plasma generator (2) positioned above the polyimide conveyor belt, after the plasma generator receives electricity, it generates atmospheric pressure low-temperature plasma in the plasma area, and the discharge power is denoted as P. The atmospheric pressure low temperature plasma processes the filler to be treated located in the plasma region to obtain the filler with grafted hydroxyl group. USE - Method for high-flux hydroxylation of inorganic filler based on low temperature plasma. ADVANTAGE - The method has simple operation, easy achievement of required conditions, good quality of inorganic filler treated by high flux of plasma, excellent grafting effect, no solvent involved in the whole process, and no toxic by-product produced.
