| titleOfInvention | Method for rapidly preparing highly regular porous anodic alumina template |
| abstract | The invention discloses a rapid preparation heightThe method of regular porous anodic alumina template comprises the following steps: folding the polished aluminum sheet into a U shape, respectively inserting two ends of the polished aluminum sheet into two independent electrolytic cells, respectively inserting a graphite plate into the electrolytic cells, wherein the two graphite plates are respectively parallel to two ends of the aluminum sheet and have equal distance with the two ends of the aluminum sheet; the total voltage loaded on the two graphite plates is 58-62V, the temperature of the electrolyte is 25 +/-2 ℃, and the PAA film is prepared. Under the condition of closed bipolar electrochemical anodic oxidation, the invention quickly reacts an aluminum sheet in high-concentration oxalic acid electrolyte to generate a highly regular PAA film, and the maximum oxidation current density reaches 151 mA cm ‑2 The maximum growth speed of the PAA film is 2.0 mu m/min, the method can control the growth speed of the PAA film by changing the solution in the two electrolytic cells and the area of the aluminum sheet in the cathode electrolytic cell, the PAA film grown under the heavy current density is not easy to generate the breakdown phenomenon, and the method can lead the aluminum sheet to realize the anodic oxidation process without wiring. |
