Embodiment 1
[0045] see Figure 1 to Figure 6 , a low-temperature plasma-based high-throughput hydroxylation method for inorganic fillers, comprising the following steps:
[0046] 1) Spread the boron nitride powder 3 to be processed on the conveyor belt 1 . The material of the conveyor belt 1 includes polyimide.
[0047] The average particle diameter of the boron nitride powder 3 is 1 μm˜5 μm.
[0048] 2) The roller-to-roller device is used to drive the conveyor belt 1 to move, so that the flat boron nitride powder 3 passes through the plasma region.
[0049] The roll-to-roll device includes several rollers for driving the polyimide conveyor belt 1 to move.
[0050] 3) At the processing temperature T, the controller sends a control signal to the power supply, so that the power supply discharges to the plasma generator 2 located above the polyimide conveyor belt 1 .
[0051]The power supply transmits alternating current to the plasma generator 2 .
[0052] 4) After the plasma generator...
Embodiment 2
[0060] See Example 1 for the high-throughput hydroxylation method of inorganic fillers based on low-temperature plasma. The device used in this method includes a polyimide conveyor belt 1, a roll-to-roll device, a power supply, a plasma generator 2, a controller, and a temperature measurement device and discharge power measuring device.
[0061] The conveyor belt 1 is used for containing and conveying boron nitride.
[0062] The boron nitride of the counter-roller device drives the conveyor belt 1 to move, so that the boron nitride moves to the plasma region.
[0063] The power supply supplies power to the plasma generator 2 .
[0064] The plasma generator 2 generates atmospheric-pressure low-temperature plasma in the plasma generation area. The atmospheric-pressure low-temperature plasma treats the boron nitride powder 3 located in the plasma region to obtain boron nitride grafted with -OH groups (hydroxyl groups).
[0065] The temperature measuring device monitors the tem...
Embodiment 3
[0070] see Figure 1 to Figure 3 , a low-temperature plasma-based high-throughput hydroxylation method for inorganic fillers, comprising the following steps:
[0071] 1) Spread the aluminum nitride powder 3 to be processed on the conveyor belt 1 . The material of the conveyor belt 1 includes polyimide.
[0072] The average particle size of the aluminum nitride powder 3 is 1 μm˜5 μm.
[0073] 2) Using a roll-to-roll device to drive the conveyor belt 1 to move, so that the flat aluminum nitride powder 3 moves to the plasma area.
[0074] The roll-to-roll device includes several rollers for driving the polyimide conveyor belt 1 to move.
[0075] 3) At the processing temperature T, the controller sends a control signal to the power supply, so that the power supply discharges to the plasma generator 2 located above the polyimide conveyor belt 1 .
[0076] The power supply transmits alternating current to the plasma generator 2 .
[0077] 4) After the plasma generator 2 receive...
