Abstract: Provided is a preparation method for a double-layer working medium target tape with a plasma-enhanced interfacial bonding force for a micro laser thruster. Aiming at the problem that in an existing micro laser thruster, when a working medium is ablated by a laser beam, due to a weak interlayer interfacial bonding force between a transparent film substrate and the coating working medium, sputtering or bulging occurs, which remarkably reduces propulsive performance, a method for treating a surface of a transparent film substrate with a low-temperature plasma is used to increase surface energy of a film and an adhesive force of a working medium layer on a surface of the film, thereby enhancing the interlayer interfacial bonding force. According to the method in the present disclosure, the transparent film substrate is treated with the low-temperature plasma.
