Description
Technical field
The present invention relates to aluminium surface treatment and modification technology field, be meant a kind of method that has super hydrophobic functional characteristic organic nano film in the aluminium surface preparation especially.
Background technology
Nano material is with its special physics, chemistry, electricity, magnetic and optical property, and obtained using widely.In the middle of the research of material surface engineering, utilizing the organic nano film material that material surface is carried out modification is one of main direction of research.
With regard to the material surface performance, wetting property is the key character of solid surface, is all to play an important role in daily life or in industrial and agricultural production.Along with the maturation gradually of and hydrophilicity research hydrophobic to material and the continuous development of bionics techniques, people are the preparation aspect with lotus leaf automatically cleaning effect surface that focused on of research.The contact angle of this surface with lotus leaf effect and water droplet is greater than 150 °, and have important feature such as waterproof, antifog, anti-oxidant, automatically cleaning, therefore can be applied to snow defence, anti-pollution, anti-oxidant and prevent aspect such as conduction of current, people are referred to as super hydrophobic surface.
At present, super hydrophobic surface prepares the aspect and has obtained very big progress, and people have also had new understanding for the formation mechanism of super hydrophobic surface.Jiang Lei is published in AdvancedMaterials, 2002,14 (24): the super-hydrophobicity that the article of 1857-1860 has disclosed natural lotus leaf surface is by its surface microstructure and chemical constitution decision, and thinks and can obtain surface super hydrophobic material by roughness that increases the hydrophobic material surface or the surface free energy that reduces the surface irregularity material.
The existing report of the preparation method of many super hydrophobic surfaces comprises that fusing-solidification method, plasma processing method, microwave plasma strengthen chemical Vapor deposition process, phase separation method, template extrusion process, ion plating, electrochemical method, sol-gel method.Yet the preparation method of the super hydrophobic surface of existing report needs special plant and instrument, and complicated operation; Secondly, because the low surface free energy material only is mode and the matrix bond that relies on Van der Waals force or physical adsorption, be restricted the work-ing life of super hydrophobic surface.For this reason, people explore method for preparing super-hydrophobic surface easy, easy handling.For example, Qian Baitai utilizes the method for chemical etching and surface fluorination to prepare super hydrophobic surface (QianBT, Shen ZQ.Langmuir, 2005,21 (20): 9007-9009), yet the process of surface fluorination is comparatively complicated and consuming time, test button need be immersed in the methanol solution of 1.0wt.% ten trifluoro octyltri-ethoxysilane of hydrolysis in advance, take out after soaking 1h under the room temperature, in baking oven, heat 1h again under 130 ℃.The Chinese invention patent application number is that 200310119322.X discloses a kind of simple super-hydrophobicity method for manufacturing thin film; it is to be that feedstock production obtains with the polymkeric substance and the longer chain fatty acid that easily are adsorbed in solid surface and contain the amido reaction active groups; therefore; combining between super-hydrophobicity film and the solid surface only is to carry out combination by Van der Waals force, and the mass-producing that is not suitable for industrial circle is used.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of super hydrophobic surface technology of preparing, a kind of preparation method of aluminum surface super hydrophobic thin film is proposed, it not only can simplify the preparation process of super hydrophobic surface, and combines with covalent linkage between organic film and the aluminum substrate surface of preparation, in conjunction with tight.
