Embodiment example 1
[0028] Add 191g of polycarbonate, 1g of polyvinylidene fluoride, 3g of other additives, and 5g of tri-n-butylmethylamine bis(trifluoromethanesulfonyl)imide salt into a Haake rheometer at 260°C for 15 minutes and then extrude through a twin-screw It is extruded, cut into pellets and dried before packaging. The temperature of each zone of the twin-screw extruder is set at 240°C-270°C. The prepared composition was thermocompressed at 250° C., and its surface resistance, volume resistance and light transmittance were measured.
Embodiment example 2
[0030] Add 186g of polycarbonate, 1g of polyvinylidene fluoride, 3g of other additives, and 10g of tri-n-butylmethylamine bis(trifluoromethanesulfonyl)imide salt into a Haake rheometer at 260°C for 15 minutes and then extrude through a twin-screw It is extruded, cut into pellets and dried before packaging. The temperature of each zone of the twin-screw extruder is set at 240°C-270°C. The prepared composition was thermocompressed at 250° C., and its surface resistance, volume resistance and light transmittance were measured.
Embodiment example 3
[0032] Add 176g of polycarbonate, 1g of polyvinylidene fluoride, 3g of other additives, and 20g of tri-n-butylmethylamine bis(trifluoromethanesulfonyl)imide salt into a Haake rheometer at 260°C for 15 minutes and then extrude through a twin-screw It is extruded, cut into pellets and dried before packaging. The temperature of each zone of the twin-screw extruder is set at 240°C-270°C. The prepared composition was thermocompressed at 250° C., and its surface resistance, volume resistance and light transmittance were measured.
