It is used for surface modification and protection of substrates. It is also excellent as a material for oxygen permeable membranes, and the oxygen permeation selectivity is improved due to the oxygen affinity of the perfluoroalkyl group.

ことは容易なことではない。However, polymer compounds into which perfluoroalkyl groups have been introduced are difficult to dissolve in solvents due to the water and oil repellency of the perfluoroalkyl groups, making them difficult to use as membrane materials. In other words, it is difficult to form ultra-thin films, which are important as surface modification materials and substrate protection materials. In addition, controlling the arrangement of perfluoroalkyl groups, which are functional groups such as water and oil repellency and oxygen affinity, on the surface of polymers is important for improving the performance of surface modification materials and oxygen separation membranes. However, controlling the arrangement on the surface is not easy.

開発が望まれている。However, since these are all amine-based polymers, their range of application is limited because the amino groups in the polymers react in the presence of acidic substances. Therefore, it is desired to develop ultra-thin film materials that have a wide range of applications and even better functionality.

のであることを見いだし、本発明を完成するに至った。The present inventors have conducted extensive research on a method for creating ultra-thin films that utilizes the hydrophobicity of perfluoroalkyl groups, and have determined that a part or all of the carboxyl groups of polyacrylic acid can be converted into 1,1-dihydroperfluorocarbons by amide bonding. The present inventors have discovered that a polymer compound obtained by modifying with an alkyl group is suitable as an ultra-thin film material, and have completed the present invention.

Measurement of the surface pressure-occupied area curve (F-A curve) when this fluorine-containing polymer was spread on pure water revealed that as the modification rate increased, the area occupied by the 1,1-dihydroperfluoroalkyl group became smaller. It can be seen that an ultra-thin film can be created. In particular, for polymer compounds with a modification rate of 30% or more, 1.1

In this case, the metal ion may be any metal ion that can form a water-insoluble salt with the carboxyl group, and examples of such metal ions include calcium, barium,
Mention may be made of metal ions derived from polyvalent metal salts such as cadmium. This metal binds to the carboxyl group of the fluorine-containing polymer compound. From the measurement of the F-A curve when this fluorine-containing polymer compound was spread on a metal salt aqueous solution, it was found that an ultra-thin film with a smaller ultimate area due to an increase in the modification rate was obtained, similar to when it was spread on pure water. It turns out that you can create one.

The LB films made of 1% fluorine-containing polymer compound showed γC values of about 16, 15, and 17, respectively. These values are smaller than the γC value of polytetrafluoroethylene, which is 18.5, and it can be said that the film exhibits excellent properties such as low surface energy, water and oil repellency, and dust resistance.

ル基の重なりにより、厚くなったと言える。When the film thickness was measured by Talystep and X-ray diffraction, an ultra-thin film of a fluorine-containing polymer compound with a modification rate of 20% or less was about 10 to 40 layers per layer, but a film with a modification rate of 30% and a high polymer compound containing fluorine The ultra-thin film of the molecular compound was about 200 Å or more per layer, and it can be said that it became thicker due to the overlap of the 1,1-dihydroperfluoroalkoxyphenyl groups.
