Between the semiconductor and conductor, film-forming substance (glue a agent), pigments and fillers, additives and solvents, including at least
One component having electrical conductivity.
According to whether the film-forming substances having a conductive, conductive coatings can be divided into the Add-type conductivity coatings and non-additive type conductive
Coatings. The former refers to the film-forming substance itself is an insulator, the coating having electrical conductivity due to the addition of the filler material or additives
; The latter refers to the film-forming material having conductivity itself, without adding a conductive component. Depending on the application characteristics, guide
The electric paint is divided into coating used as a conductive body (such as hybrid integrated circuits, printed circuit boards, etc.), the radiation screen
Shield coatings, antistatic coatings and electrochromic coating and the photoconductive coating.
(1) Add conductive coating film-forming materials of the conductive not only by the selection of a conductive material, but also by the polymerization
Material, additives, solvents, and manufacturing processes. Movies maximum conductivity of the kind of the polymer matrix of the coating
Ring, the smaller the surface tension of the polymer coating (such as polyethylene) specific surface tension of the polymer coating (such as nylon)
Higher conductivity. Addition ships polymer is an insulator range, but its conductivity differ, the same
Also affect the conductive coating. Some of the volume resistivity of the polymer compound are given in Table 3-11.
