The present invention relates to a method for forming a micro-sized thin film by using a high-functional nano-inorganic composition. The high functional properties are mainly directed to a nano-inorganic coating technique wherein: mechanical characteristics including surface hardness and wear properties are excellent; chemically very stable characteristics, such as water resistance, acid resistance, and alkali resistance, are shown; and thermal stability characteristics are excellent through the formation of an inorganic material. Furthermore, the functional control of super-hydrophilic, hydrophilic, and hydrophobic characteristics is possible according to the coating method; contamination resistance and easy-clean characteristics of surfaces are excellent according to thin film coating; and excellent optical characteristics are shown in terms of light transmittance, light reflectance, and the like.

Description

technical field [0001] The present invention is a technology related to the preparation of highly functional nano-inorganic composition and the method of using it to form fine-sized thin film. The above-mentioned high functionality mainly has very excellent mechanical properties, mainly including surface hardness and wear resistance, and has chemical stability properties such as water resistance, acid resistance, and alkali resistance, and has excellent thermal stability due to its composition of inorganic materials. Moreover, the functional control of super-hydrophilic, hydrophilic, and hydrophobic properties can be carried out according to the required properties of the prepared composition, and according to the film coating, it has excellent surface anti-fouling and easy-cleaning (Easy-Clean) properties, It has excellent optical properties in terms of light transmittance and light reflectance.

Problems solved by technology

[0005] However, in the case of nano-inorganic materials that appear in the prior art of the above-mentioned patents, their solid content is more than tens of wt%, so the thickness to be coated is several hundred to several thousand nanometers. It can be seen that by conventional coating methods When coating, problems such as whitening and microcracks occur during heat treatment, and due to excessive solid content, it is difficult to achieve a smooth coating with a coating thickness of tens of nanometers

[0006] In particular, when the coating thickness is thick, defects inside the coating and air layers are easily formed in the heat treatment process, resulting in a rapid decrease in the durability of parts passing through such defects

Also, when forming a coating film with the materials in the above patents, there are many differences in various functional parts
