| 中文摘要: |
| 目的 通过对阳极氧化铝膜（AAO）表面化学接枝甲基丙烯酸甲酯，改变其表面的粗糙度和分子结构，从而实现AAO膜表面润湿行为的可控。方法 采用二步阳极氧化法制备六方柱形的多孔AAO膜，结构高度有序，并对AAO膜表面进行硅烷化（KH-570）处理，采用活性聚合的方法在其表面接枝上甲基丙烯酸甲酯。采用原子力显微镜（AFM）、X射线衍射仪（XRD）和接触角测定仪对AAO膜及改性后的AAO膜进行了结构表征和润湿行为研究。探讨了阳极氧化的工艺条件及接枝甲基丙烯酸甲酯对AAO膜的形貌和润湿性能的影响。结果 AAO膜孔径在100 nm左右，六边形孔洞分布均匀，并且六边形孔洞垂直于AAO膜表面，孔洞与孔洞平行，通过对其表面接枝甲基丙烯酸甲酯，使得AAO膜的表面水接触角先增大后减小。结论 AAO膜表面的润湿行为，可以通过AAO膜表面化学改性和表面粗糙度共同作用而得以调控。 |

| The work aims to control wetting behavior of anodic aluminum oxide (AAO) film surface by chemical grafting methyl methacrylate on anodic aluminum oxide (AAO) film surface and changing roughness and molecular structure of the surface. Highly nanoporous ordered AAO film was fabricated in a two-step anodization method. The structure of nanoporous AAO film featured in close-packed hexagonal arrangement of approximately hemispherical concaves. Surface of the nanoporous AAO film was further treated with 3-Methacryloxypropyltrimethoxy (KH-570). Then, the AAO film modified with poly(methyl methacrylate) was prepared by grafting methyl methacrylate onto the surface of nanoporous AAO film in the method of living polymerization. Structural characterization and wetting behavior study were performed to AAO film and modified AAO film using atomic force microscope (AFM), X-ray diffractometer (XRD) and contact angle tester. Effects of anodizing process conditions and methyl methacrylate grafting on morphology and wettability of AAO film were investigated. The nanoporous AAO film was amorphous, its pore diameter was about 100 nm, and hexagonal holes were well distributed in parallel and perpendicular to the surface of AAO film. Water contact angle of the AAO film first increased and then decreased by grafting methyl methacrylate. The wetting behavior of AAO film surface can be controlled by chemical modification of AAO film surface and surface roughness together. |
