Abstract (en)
An electrothermal filament is produced by mixing carbon black with a grafting monomer and initiator to form grafted copolymers and then adding a terminating agent to the mixture to stop the grafting; coating filaments with grafted copolymers by passing the filaments through the grafted copolymers to apply a carbon black layer on the filaments; and laminating membranes on the filament. An independent claim is also included for an electrothermal filament produced by the inventive method.
