When it is less than m, good transparency can be maintained. On the other hand, if the particle size is 50 ni or more, the conductive film becomes translucent at lam thickness, which is not preferable. Also,
This type of tin-containing indium oxide (ITO) ultrafine particles are
Because its conductivity is based on electron conduction, its conductivity is stable even with changes in temperature and humidity, and since it is an oxide, it does not change in quality due to oxygen, moisture, etc. Stable conductivity is exhibited by the tin-containing indium oxide (ITo) ultrafine particles, and a transparent conductive film having stable conductivity can be obtained. Such particle size is 50n
The content of tin-containing indium oxide (rTo) ultrafine particles of m or less in the transparent conductive film is determined to improve the transparency of the transparent conductive film and fully exhibit its stable conductivity.
The content is preferably 60% by weight or more based on the total solid content of the transparent conductive film.

き、導電性を充分に向上させることができる。Furthermore, the silazane used in the present invention may have either a polyethyleneoxy group or a polypropyleneoxy group, or may have both, and in either case, the molecule itself has conductivity. have. Further, functional groups such as polyethyleneoxy groups and polypropyleneoxy groups of this type of silazane have extremely strong adsorption power to solid surfaces. However, when used together with ultrafine tin-containing indium oxide (ITO) particles with a particle size of 50 nm or less, this type of silazane is easily chemically adsorbed on the surface of the ultrafine tin-containing indium oxide (ITO) particles at room temperature, and the silazane is Through this, the frequency at which ultrafine tin-containing indium oxide (ITO) particles come into contact with each other is greatly increased. Therefore, by using this kind of silazane in combination, the conductivity of the transparent conductive film is improved by about an order of magnitude compared to the case where this silazane is not included. As a result, the transparent conductive film can have a thickness of 1 μm or less, exhibit a surface electrical resistance of 10 5 Ω/□ or less, and can sufficiently improve conductivity.

分子導電膜に比べて、接着性が飛躍的に向上される。Furthermore, when this type of silazane is used in combination with tin-containing indium oxide (ITo) ultrafine particles with a particle size of 50 nm or less,
Since the tin-containing indium oxide (IT'O) ultrafine particles also act as a filler, the strength of the transparent conductive film is strengthened and the abrasion resistance of the transparent conductive film is improved. In addition, since this type of silazane is a polymeric compound that is easily chemically adsorbed on the surface of tin-containing indium oxide (ITO) ultrafine particles at room temperature, it has improved adhesion to insulating substrates, such as polyacetylene, polypyrrole, etc. , the adhesion is dramatically improved compared to conductive polymer conductive films such as polythiophene.
