剤の含浸が容易に進行できる利点を有する。[A method for producing porous aluminum oxide film by anodic oxidation of aluminum core, in which porous aluminum oxide film is produced in an electrolytic bath.
Using a neutral bath in which the membrane is difficult to dissolve, low temperature and large TLF
There is an electrolytic method using direct current of fL density. However, when such an electrolytic method is used, the growth of the film is slow and a thick film cannot be easily formed.
Although a thick film could be easily formed by using a fl electrolytic bath, the hardness was still not sufficient. Preferably, an extremely hard film can be obtained by forming an aluminum oxide porous film by an electrolytic method that periodically contains a negative component with a pulsed current waveform, and then heat-treating it in a vacuum. The produced porous film has relatively large pore diameters and good straightness, so it has the advantage that impregnation with the filler can proceed easily.

に結合させて加水分解させることによりシロキサン結合
を作る。After forming an aluminum oxide porous film in this way, an organosilicon compound having two different reactive groups (a hydrolyzable group and a functional group with affinity for fillers) in its molecule, that is, a silane coupling agent, is used. A siloxane bond is created by bonding the group to aluminum oxide and hydrolyzing it.

中に残留している硫化水素。The chemical reaction that creates this siloxane bond forms a molecular layer of durable, low surface energy silicon compounds. At this time, if the vacuum heat treatment effect is insufficient, hydrogen sulfide remains in the film.
硫化アルミなどの硫黄化合物がこの化学結合を弱めるた
め、真空熱処理を充分に行なう必要がある。Since sulfur compounds such as aluminum sulfide weaken this chemical bond, sufficient vacuum heat treatment is required.
一方、この有機珪素化合物の選択基準は重要で、充填剤

択する必要がある。充填剤は誘電体特性、潤滑性、湿度
特性などを考慮して選択する。On the other hand, the criteria for selecting this organosilicon compound are important, and it is necessary to select the optimal functional group in order to maximize the bonding with the filler. The filler is selected in consideration of dielectric properties, lubricity, humidity properties, etc.

By arranging it on the surface, it has lubricity that makes it difficult for deposits such as toner to adhere.

It can be seen that the surface energy is lower than that of No. 10, and the lubricity and humidity characteristics are excellent. In particular, when Comparative Examples 6 to 10, which do not contain fluorine, and Examples 1 to 5 are compared, Examples 1 to
It can be seen that No. 5 has better lubricity and humidity characteristics and can withstand long-term use.
