It is also possible to laminate an arbitrary number of the same molecular films, or to alternately laminate different molecular films.
上記従来技術はＬＢ膜のファイバー化、高密度化につい
ては配慮されておらず、ファイバーへの応用については
困難であるという問題があった。The above-mentioned conventional technology does not take into account the fiberization and high density of the LB film, and there is a problem in that it is difficult to apply it to fibers.
本発明の目的は、高配向性と高密度性を同時に実現した
Ｌ Ｂファイバーを作製することにある。An object of the present invention is to produce an LB fiber that simultaneously achieves high orientation and high density.

として、ガラスファイバー、炭素繊維、酸化物超伝専体
繊維などが挙げられる。またこれらの繊維表面に金属。The above objective is achieved by laminating oriented molecules onto a core fiber. Here, the oriented molecules include straight chain fatty acids and their divalent metal salts. In addition, it is generally desirable that the core fiber has a strong structure and flexibility. Examples of materials that meet these conditions include glass fiber, carbon fiber, and oxide superconductive fiber. There is also metal on the surface of these fibers.
半通体などの層を形成して用いても良い。芯となる繊維
の断面形状には特に制限はない。A layer such as a semi-through body may be formed and used. There are no particular restrictions on the cross-sectional shape of the core fiber.
これら芯となる繊維に、単分子膜を巻き付ける方法によ
り、高配向性ＬＢファイバーを作製する。Highly oriented LB fibers are produced by wrapping a monomolecular film around these core fibers.
芯となる繊維と単分子膜面とのなす角を一定に保ちなが
らの繊維の並進運動と回転運動により、繊維上に単分子
膜を効率よく規則性よく積着させることが可能である。By performing translational and rotational movements of the fibers while keeping the angle between the core fiber and the surface of the monomolecular film constant, it is possible to deposit the monomolecular film on the fibers efficiently and with good regularity.

いう心配はない。Generally, a monomolecular film formed by such a method has excellent orientation, but is not necessarily excellent in terms of density. As a method of increasing the density of aggregates of molecules mainly composed of carbon, there is a method of performing graphitization treatment. this is,
By heat-treating the sample at 1000-3000℃,
This improves carbon orientation and laminated order. According to this method, the distance between adjacent carbons can be set to 1.42 people, and the stacking interval between carbon surfaces can be set to 3.35 people. In the case of a two-dimensional monomolecular film formed on a substrate, there is a problem in that cracks occur on the surface due to shrinkage in volume due to graphitization. On the other hand, in the case of the present invention, shrinkage of one volume has the effect of reinforcing the surface of the fiber, so there is no fear that cracks will occur on the surface.

通りの巻き付けが終了後。While keeping the angle O between the monomolecular membrane surface and the core fiber constant, the monomolecular film can be efficiently and regularly wrapped around the core fiber by the translational and rotational movements of the core fiber. The direction of translation is preferably perpendicular to the longitudinal direction of the core fiber. At this time, if the radius of the core fiber is r, the angular velocity ω, and the translational speed is υ, then υ
If the relationship = r ω holds true, the monomolecular film can be wrapped in just the right amount. Furthermore, the adhesion density of the monomolecular film can be adjusted by θ. When θ=90″, −
After the street wrapping is finished.

。It is also possible to continuously orient the monomolecular film in the longitudinal direction of the core fiber by moving it in the vertical direction by the length of the monomolecule and wrapping it again using a Pituzo cord or the like.
