A process for producing a coated electrical steel strip includes application of a pretreatment layer over a first flat side of a rolled electrical steel strip. The layer thickness of the pretreatment layer is in the range from 10 nm to 100 nm, in particular from 20 nm to 50 nm. The rolled electrical steel strip which has been coated with the pretreatment layer is then coated with an insulating lacquer layer over the pretreatment layer. The insulating lacquer layer is applied by roll application using a roll and no deliberate drying and/or crosslinking of the pretreatment layer is carried out after application of the pretreatment layer and before coating with the insulating lacquer layer.

Disclosed is a method of manufacturing a transmission line using a nanostructured material and a method of manufacturing the transmission line. The transmission line using a nanostructured material includes a first nanoflon layer formed of nanoflon, a first insulating layer located above the first nanoflon layer, a first pattern formed by etching a first conductive layer formed on the first insulating layer, and a first ground layer located below the first nanoflon layer. Here, the nanoflon is a nanostructured material formed by electrospinning a liquid resin at a high voltage.

A preparation method for a metal matrix composite wire includes the following steps: 1) preparing a metal inner core; 2) preparing a glass-resin mixture; 3) dissolving self-adhesive resin in a solvent to prepare a self-adhesive resin solution; 4) uniformly coating the glass-resin mixture on a surface of the metal inner core, then coating the self-adhesive resin solution on a surface of the glass-resin mixture, and performing drying at a temperature of 80 C. to 150 C.; and 5) repeating the step 4) until a thickness of the glass-resin mixture plus the self-adhesive resin reaches 2 to 10 m. When an inductor is prepared by using the composite wire, the inductor may have relatively good weather resistance, a relatively good dielectric voltage-withstand capability, as well as relatively good high-temperature resistance and electrical performance.
