0215[0122] Evaluation 1

0216( Electrification state)

0217The following operations were performed in order to judge the electric charge state of the surface of an evaluation board. First, temperature 1 Under 8"C and the atmosphere of 40% of humidity, prepare the sheet small piece made from polypropylene (2 mm in width, length 15 Omm, 0.005 g weight), a small piece is made to rub against a cotton cloth, and it is static electricity negative on the small piece surface. You made it charged. Next, an evaluation board is perpendicularly arranged using the bookstand made from polystyrene, and it is a small piece. It is lOmn about an interval! Or [ to which a small piece sticks at an evaluation board after being referred to as *20mm / or or / opposing ] It observed. When adsorbing, it judged with the substrate face being tinged with positive charge, and place Synthesis to repel judged with the substrate face being tinged with the minus electric charge (beforehand). They are line ! and rebounding about operation that it is the same between the rubbed small piece and a Teflon stick (registered trademark) (being charged negatively is known) 8 mm in diameter. It checked carrying out. A result is shown in a table.

0218[0123] (Surface property)

0219The following operations were performed in order to judge the hydrophilic 'water repellence of an evaluation substrate face. It is Loading horizontally. It is less than 10-mm height power to the evaluation board which carried out Place. One-drop (0. 028*0. 029 g) dropping of the pure water was carried out by the syringe. next, the angle of contact which the dropped waterdrop forms in the surface of an evaluation board -- eyes seeing -- the case where it observes and 40 degrees of angles of contact are the following -- hydrophilicity -- With water repellent(ing) 80 " in the above case -- seal It carried out constant. A result is shown in a table.

0222[0126] The substrate which is covered with an insulating polymer membrane and has minus electric charge' water repellence on the surface in this way is the table if the substance which has positive charge as a foundation layer of an insulating polymer membrane is arranged. An electrification state just changes, without losing the water repellence of a field. Thereby, it is Pollution prevention of a substrate. The anti-oxidization effect of Decreased, a base, and an insulating polymer membrane can be acquired.

0223[0127] Evaluation 2

0224It is [ in / board / each / of Example 2 and comparative examples 1 and 2 / evaluation / Saga Prefecture ] an exposure examination. It carried out and evaluated the pollution state of each substrate face, and the angle of contact with water. Specifically, it is each evaluation machine. The board was exposed outdoors to sunlight for 18 days, and it was neglected for two days in the dark place after that.

0225[0128] a result -- a table -- it is shown in 3. the "a little more than water repellence" in table 3 -- an angle of contact with water -- 100 degrees -- the above -- 12 Mean being 0 or less degree. The angle of contact with water of "water repellence" is below 100 degrees above 80 degrees. It is a meaning about a certain thing being meant and 20 degrees of angles of contact [ 5 degrees of ] of "hydrophilicity" with water being above below. It carries out. The angle of contact carried out visual measurement with the manual angle gauge. It was presupposed it "is nothing [ "pollution ] about the state where consider it as pollution owner" and it has not adhered" the state where many white spots have adhered on a substrate face. There was three rain during exposure exam time.

0228[0130] a table -- power in which comparative examples 1 and 2 are strong water repellence irrespective of an exposure examination as shown in 3 Examples 1 and 2 serve as hydrophilicity by sunlight exposure, and, on the other hand, serve as water repellence at the time of being sunlight un-exposed. therefore, a table -- the positive charge substance which covered fluorine system Water repellent from the result shown in 3 -- substrate face By arranging shows that the water-repellent' hydrophilicity of a substrate face can be controlled. What Evaluation 2 was the same result also as two power performed twice.
