| Zusammenfassung: | The invention discloses a method for modifying an ultra-high molecular weight polyethylene microporous film. The method comprises the following steps of flatly paving the ultra-high molecular weight polyethylene microporous film on a receiving platform of an electrostatic spraying device; carrying out polymer spraying treatment on the ultra-high molecular weight polyethylene microporous film with pre-prepared polymer spraying solution by utilizing the electrostatic spraying device; and controlling the amount of microparticles on the surface of the ultra-high molecular weight polyethylene microporous film by controlling the spraying time so as to obtain the modified ultra-high molecular weight polyethylene microporous film. The ultra-high molecular weight polyethylene microporous film modified through the method has high porosity and charging and discharging capacity and good cycling performance. |
