Problems solved by technology

However, the inventors have found that although the device can realize a single corona polarization and discuss the polarization uniformity, it does not consider the polarization degree and stability
[0006]In summary, the existing polarization devices usually can only achieve a single high-temperature thermal polarization or corona polarization, and cannot achieve multi-purpose and multiple polarizations in one machine The optimal combination of methods, and little consideration is given to the influence of the gas environment on the polarization performance

Embodiment approach B

[0047] Embodiment B: the polarization processing environment is a protective gas environment, the air inlet 120 and the air outlet 121 are opened during use, and nitrogen is continuously introduced as the protective gas; the other is the same as the embodiment A.

Embodiment approach C

[0048] Embodiment C: The grid electrode 220 is removed, and a voltage is directly applied to the PVDF film 210 through the top electrode 230;

Embodiment approach D

[0049] Embodiment D: as image 3 As shown, high temperature thermal polarization was performed and the grid electrodes in the device were removed. Silicon oil is filled in the groove of the first stage 180 as a liquid environment, the sheet-shaped PVDF film 210 is bent and immersed in the silicone oil and contacted with the bottom electrode 200, and the atmospheric environment polarization treatment is selected. Start the first step motor 160, and drive the first stage 180 along the guide rail 140 to the top electrode 230 through the first precision screw 170. figure 2 The moving speed of the first precision screw 170 and the distance from the top electrode 230 are precisely controlled by the stepping motor control device 131, so that the top electrode 230, the PVDF film 210, and the bottom electrode 200 are in contact. After the distance between the PVDF film 210 and the top electrode 230 is adjusted, start the heater 130 and adjust the temperature in the box 110 to a const...
