発明の概要(英語) The purpose of the present invention is to provide a surface treatment technology that makes it possible to give a variety of large-area base material surfaces excellent surface functionality. According to the present invention, an organic silane that includes a polymerization initiation group and is represented by X-R1-(Ph)k-(R2)m-Si-R3nR43-n is used as the organic silane when a base material is coated with a precursor liquid that includes an organic silane and a metal alkoxide, and a sol-gel method is used to form a polymerization initiation layer. (In the formula, X represents a halogen atom, R1 represents a C1–3 alkylene group, Ph represents a phenylene group, R2 represents a C1–10 alkylene group that may be via an oxygen atom, R3 represents a C1–3 alkoxy group or chloro group, R4 represents a C1–6 alkyl group, k is 0 or 1, m is 0 or 1, and n is 1, 2, or 3.)
従来技術、競合技術の概要(英語) BACKGROUND ART
Effective solid surface as a surface modifying material is a polymer brush has attracted attention. Brushes, the surface of the substrate after the formation of the polymerization initiation layer, the monomer and a polymerization catalyst and a polymerization initiation layer in contact with the polymerization of the monomer, the polymerization initiation layer from the surface by the extension of the polymer chain is formed, the polymerization of the monomer, a narrow molecular weight distribution can be formed on the surface of the polymer chain by atom transfer radical polymerization is started (SI-ATRP method: Surface-Initiated Atom Transfer Radical Polymerization) is preferably used. Therefore, the formation of the polymerization initiation layer to a substrate is important and, depending on the chemical properties of the substrate is necessary to prepare the polymerization initiator.
A normal layer may be formed by a polymerization initiator, polymerization initiator molecules, vapor phase or liquid phase by a method of forming the surface of the substrate has been generally used. For example, made of glass or silicon substrate to a silane coupling compound, thiols can be directed to the group of gold, aluminum-iron phosphate compound to the substrate and the like are used. However, Patent Document 1 (0002), Patent Document 2 (0004) or the like as described, depending on the material of the substrate, the substrate of the chemically bonded to the appropriate compound needs to be selected, a general method of forming a polymerization initiation layer is demanded.
In addition, in the case where the polymerization initiation layer formed by a vapor phase method, for example, organic silane such as silane are used for the steam, the heating processing in the large-sized reaction apparatus is indispensable. In addition, an inorganic substrate to the surface of the polymerization initiation layer is formed although the prior art, PET resin or polycarbonate or the like on the substrate surface, the characteristics of the substrate, without damaging the shape of the polymerization initiation layer is formed has been difficult.
In addition, in the case where the polymerization initiation layer formed by liquid phase method, for example, organic silane such as aminosilane liquid dissolved in an organic solvent is impregnated with a predetermined period of time the substrate is reacted, is not suitable for processing a large substrate. In addition, in the case where the substrate is a plastic, depending on the type of the organic solvent, impregnating the base material by a long period of time or may be subjected to solvent attack.
Various solve such a problem the surface of the substrate of a method for fixing a polymerization initiator, in the above Patent Document 1, is used as polydopamine, polydopamine film becomes the origin of the polymerization reaction of the polymerization initiator has been proposed and fixed to each other. However, the method further comprises, a dopamine solution at room temperature by oxidation polymerization polydopamine after films are formed, the initiator further to immobilize or through a two step reaction is complicated and, moreover, the formation of the polymerization initiation layer containing polydopamine basic conditions are required and, the substrate does not want a basic problem that does not match.
In addition, in Patent Document 2, ivy or analog included in the crosslinked structure made of a phenol derivative or catechol derivatives in, a halogen group and a compound having a polymerization initiation site is incorporated into the composite material has been proposed and used, the composite is in the reaction stage 1 can be manufactured easily and in a short time, the silicon substrate, metal, glass and other, a phenolic resin such as plastic and be bonded to a substrate of various polymer-coated material can serve as a precursor of the invention. However, the composite is, catechol derivatives or a phenol derivative, a halogen group compound having a polymerization initiation site after mixing, is produced by the curing, during the mixing, the ultrasonic processing and the like, it is necessary to secure a uniform distribution. In addition, the synthesis of the materials is required, such as consuming a large amount of cost is used, a large area and is unsuited for mass production.
In this way, conventionally, the formation of the polymerization initiation layer to the substrate surface a special apparatus and/or processing conditions may be essential in the reaction, for convenience, is inferior in productivity and a problem, in particular, to a large-area substrate is difficult to form and the polymerization initiation layer, for example roll-to-roll system film-forming apparatus that uses a large area mass production and is unsuitable for.
On the other hand, the use of the brushes, to be more oil-hatsu in water is applied as a surface has been proposed. In such a brush, in Patent Document 3, the brush is formed as a pretreatment method of a solid surface, an amino group or a hydroxyl group in the silane coupling agent having a solid surface amino groups on the surface of the solid-state processing or after introduction of the hydroxy group, amino group or hydroxy group and a 2-reaction Methylpropionic acid derivative-2-bromo by, in which the polymerization initiating group on the surface solid 2-a method for the introduction of bromoisobutyryl bromide respectively.
However, the patent has been proposed in the literature is, immersed in an aqueous solution of predetermined pH and then the obtained oil-hatsu excellent brush or an object, in order to achieve this object, the polymerization initiator is in the '2-bromoisobutyryl bromide group' was introduced into the fixed surface, the specific water soluble monomers are polymerized and hence, various large-area surface of the substrate, various brush easily and uniformly to a method for forming is not considered in any way.
