Embodiment example 1
[0031] Add 193g of polyvinylidene fluoride, 3g of other additives, 4g of 1-butyl-3-methylimidazolium hexafluorophosphate into the Haake rheometer at 190°C for 15min at a speed of 50 rpm, and then pass through the twin-screw The extruder extrudes and cuts into pellets and packs after drying. The temperature of each zone of the twin-screw extruder is set at 160°C-190°C. The prepared composition was hot-pressed at 190°C, and its antistatic properties, mechanical properties and light transmittance were measured and analyzed by DSC, TEM and FTIR. The results of the analysis are shown in the accompanying drawings.
Embodiment example 2
[0033] Put 189g of polyvinylidene fluoride, 3g of other additives, and 8g of 1-butyl-3-methylimidazolium hexafluorophosphate into a Haake rheometer at 190°C for 15 minutes at a speed of 50 rpm, and then pass through a twin-screw The extruder extrudes and cuts into pellets and packs after drying. The temperature of each zone of the twin-screw extruder is set at 160°C-190°C. The prepared composition was hot-pressed at 190°C, and its antistatic properties, mechanical properties and light transmittance were measured and analyzed by DSC, TEM and FTIR. The results of the analysis are shown in the accompanying drawings.
Embodiment example 3
[0035] Put 177g of polyvinylidene fluoride, 3g of other additives, 20g of 1-butyl-3-methylimidazolium hexafluorophosphate into the Haake rheometer at 190°C for 15min, at a speed of 50 rpm, and then pass through the twin-screw The extruder extrudes and cuts into pellets and packs after drying. The temperature of each zone of the twin-screw extruder is set at 160°C-190°C. The prepared composition was hot-pressed at 190°C, and its antistatic properties, mechanical properties and light transmittance were measured and analyzed by DSC, TEM and FTIR. The results of the analysis are shown in the accompanying drawings.
