The present application discloses an insulated wire and a preparation method thereof, a coil and an electronic/electrical device. According to the insulated wire, a bonding layer containing PEEK nano-powder is arranged between a conductor and a PEEK resin insulating layer, and a bonding agent for forming the bonding layer contains organic solvent, polyamide-imide resin and PEEK nano-powder material which are mixed. The bonding layer can be well bonded with both the conductor material and the PEEK resin insulating layer, so that the produced insulated wire rod has good adhesion, and cracking and detachment will not appear during application.

In the coating method, a pipe for transporting oil and/or gas mined from underground is provided. An acid curable resin is passed through the pipe to adhere the acid curable resin to at least a part of an inner wall of the pipe. Then, an acid curing agent is passed through the pipe to allow the acid curing agent to make contact with the acid curable resin such that the acid curable resin is cured.
