Description
技术领域technical field
本发明属于功能材料领域；具体涉及超级浮力疏水金属网船及其制备方法。The invention belongs to the field of functional materials; in particular, it relates to a super-buoyancy hydrophobic metal mesh boat and a preparation method thereof.
背景技术Background technique
一般来说，超疏水性表面可以通过两种方法来制备：一种是在疏水材料表面构建粗糙结构；另一种是在粗糙表面上修饰低表面能的物质。通过这两种方法已经制备出了非常多的超疏水材料材料。但是，这里的粗糙度通常指微米或纳米级的粗糙度，通过在具有宏观粗糙度的材料表面构造超疏水表面还不多见。关于金属网船及其制备方法还未见报道。In general, superhydrophobic surfaces can be prepared by two methods: one is to build rough structures on the surface of hydrophobic materials; the other is to modify low surface energy substances on rough surfaces. A lot of superhydrophobic materials have been prepared by these two methods. However, the roughness here usually refers to the roughness of micron or nanometer scale, and it is rare to construct a superhydrophobic surface on the surface of a material with macroscopic roughness. There is no report about the metal mesh boat and its preparation method.
发明内容Contents of the invention
本发明目的是提供了一种超级浮力疏水金属网船及其制备方法。The object of the present invention is to provide a super buoyancy hydrophobic metal mesh boat and a preparation method thereof.
本发明中超级浮力疏水金属网船是由外层包裹厚度为20nm～50nm的聚全氟烷基硅氧烷层的金属网制成，形状为船形，金属网的孔径在40目以上。The super-buoyancy hydrophobic metal mesh boat in the present invention is made of a metal mesh wrapped with a polyperfluoroalkylsiloxane layer with a thickness of 20nm to 50nm on the outer layer.
本发明中超级浮力疏水金属网船的制备方法是按下述步骤进行的：一、对孔径在40目以上的金属网进行脱脂处理，然后室温下晾干，再经碱洗、水洗后烘干；二、室温下，按重量百分比将0.1％～8％全氟烷基硅氧烷、1％～10％的水、1％～10％的冰醋酸和余量的乙醇混合，然后超声处理30min～120min，得到全氟烷基硅氧烷溶液；三、将金属网浸入步骤二得到的全氟烷基硅氧烷溶液中10s～60s，取出后自然晾干或吹干；四、重复步骤三的操作2～8次；五、将经步骤四处理后的金属网在110℃条件下烘干3～12h，在金属网表面得到厚度为20nm～50nm的聚全氟烷基硅氧烷层；六、将经步骤五处理的金属网加工成船形；即得到超级浮力疏水金属网船。The preparation method of the super-buoyancy hydrophobic metal net ship among the present invention is carried out according to the following steps: one, carry out degreasing treatment to the metal net with aperture more than 40 orders, then dry at room temperature, then dry after alkali washing and water washing 2. At room temperature, mix 0.1% to 8% perfluoroalkyl siloxane, 1% to 10% water, 1% to 10% glacial acetic acid and the rest of ethanol by weight percentage, and then ultrasonically treat for 30 minutes ~120min to get the perfluoroalkylsiloxane solution; 3. Immerse the metal mesh in the perfluoroalkylsiloxane solution obtained in step 2 for 10s~60s, take it out and dry it naturally or blow dry; 4. Repeat step 3 2 to 8 times; 5. Dry the metal mesh treated in step 4 at 110°C for 3 to 12 hours, and obtain a polyperfluoroalkylsiloxane layer with a thickness of 20nm to 50nm on the surface of the metal mesh; 6. Process the metal mesh processed in step 5 into a boat shape; promptly obtain a super buoyancy hydrophobic metal mesh boat.
本发明采用化学处理的方法，在具有宏观粗糙度的金属网表面实现疏水，并在水中具有超浮力性能(所指超浮力性能是指在金属网船本身通过排水所获浮力外还具有的额外浮力)。本发明可用于制造水上交通工具，如水上机器人、微型环境监测器、船舶等。由于疏水结构能大幅度降低材料在水中甚至空气中的运动阻力，针对本发明所述材料的研究对设计高速水上、水下和空中交通工具也将具有重要参考价值。The present invention adopts the method of chemical treatment to realize hydrophobicity on the metal mesh surface with macroscopic roughness, and has super-buoyancy performance in water (the super-buoyancy performance refers to the additional buoyancy that the metal mesh boat itself has by draining water) buoyancy). The invention can be used to manufacture water vehicles, such as water robots, miniature environment monitors, ships and the like. Because the hydrophobic structure can greatly reduce the movement resistance of the material in water or even in the air, the research on the material of the present invention will also have important reference value for the design of high-speed water, underwater and air vehicles.

采用下述试验验证本发明效果：Adopt following test to verify effect of the present invention:
船形为方形：长40mm×宽35mm×高10mm，进行接触角(水是滴在金属网船上的)和浮力性能试验，结果如1-4所示。The shape of the boat is square: length 40mm×width 35mm×height 10mm. The contact angle (water is dropped on the metal mesh boat) and buoyancy performance tests are carried out, and the results are shown in 1-4.
由图1和2是60#(60目)金属网表面与水接触角的二维及三维照片。图3为具有不同孔径的金属网的浸润性测试结果，结果表明，具有不同孔径的金属网表面均具有疏水性。图4为80目金属网船的载重能力测试，从图中可以发现，金属网船不但能轻易的漂浮在水面，并且具有非常大的载重能力。图5中显示的是具有不同孔径的金属网船的载重量。从图中可以看出，金属网船不但具有非常大的载重能力，并且由于其表面的疏水性，还能提供额外浮力(船体积排水所得浮力外的浮力)。Figures 1 and 2 are two-dimensional and three-dimensional photos of the contact angle between the surface of the 60# (60 mesh) metal mesh and water. Figure 3 shows the wettability test results of metal meshes with different pore sizes, and the results show that the surfaces of the metal meshes with different pore sizes are all hydrophobic. Figure 4 is the load capacity test of the 80-mesh metal mesh boat. It can be seen from the figure that the metal mesh boat can not only float easily on the water surface, but also has a very large load capacity. Shown in Figure 5 is the deadweight of metal mesh boats with different apertures. It can be seen from the figure that the metal mesh boat not only has a very large load-carrying capacity, but also provides additional buoyancy (the buoyancy beyond the buoyancy obtained by the displacement of the boat volume) due to the hydrophobicity of its surface.
