Abstract
The invention relates to a method for preparing a compressible micron/ nano-structured ultra-sparse coating, which is characterized by comprising the following steps of: dispersing nickel chloride or ferric chloride and myristic acid powder into absolute ethyl alcohol to form an even electrolyte; electrolyzing two metal sheets which are not limited in size and taken as electrodes for a certain time at a certain direct current voltage, thus forming a certain amount of powder (either hydrophobic powder or hydrophobic powder is ok) on a cathode; and finally adhering the powder by a tag or an adhesive tape and compacting the powder. The obtained coating has extremely good ultra-sparse performance, and can be transferred to any object according to requirements. The simple and rapid method is utilized to obtain the micron/ nano-structured composite coating on a tag or an adhesive tape for the first time. The ultra-sparse coating has good ultra-sparse performance, simultaneously is easy to repair, and can be easily transferred, thereby greatly reducing requirements on self performance of a material, and being expected to be applied to various engineering materials in a large scale.
Description
Technical field
The present invention relates to a kind of preparation and can press the method for the super open coat of micro, prepare the method for powder, particularly a kind of super open coat of micro metal-powder that on label paper or adhesive tape, forms by TETRADECONIC ACID and nickelous chloride or iron(ic) chloride nonaqueous electrolyte through overcompaction.
Background technology
In daily life and industrial production, surface wettability is that exosyndrome material is marked a very important index.It is generally acknowledged glassware for drinking water had greater than 150 ° of contact angles and material with less roll angle and be super thin material.Be subjected to the especially inspiration of lotus leaf automatically cleaning characteristic of bionical thought, the researchist is by all having made up super thin film at the material that makes up uneven surface on the low surface energy material and modify low surface energy on coarse surface tissue, relevant preparation method is a lot, laser/plasma etching the method that comprises complicated process of preparation, simple immersion process consuming time, caustic solution fast, with UV-irradiation to specific TiO
2Base film is realized conversion method of super-hydrophobic and super hydrophily or the like.But existing outstanding problem is in these methods: the realization of super thin performance also greatly depends on experiment condition, and the super thin film of preparation is difficult to realize transfer that as long as the micro on the film is destroyed, its super thin performance disappears immediately.For this reason, seek a kind of efficient, simple, cheap, handled easily, be easy to big area production and reparation and transferable super open coat technology and become one of the hot issue in daily life and industrial production field.
Summary of the invention
The technical problem that solves
For fear of the deficiencies in the prior art part, the present invention proposes the method that a kind of preparation can be pressed the super open coat of micro, adopted the single step on metals such as stainless steel, aluminium flake and copper sheet of nonaqueous electrolyte method to prepare certain thickness iron content or nickel metal powder at cathode surface fast, then powder evenly is sticked and coated on label paper or the adhesive tape and compacting, so just on label paper or adhesive tape, prepares super open coat with micro.
Technical scheme
A kind of preparation can be pressed the method for the super open coat of micro, it is characterized in that step is as follows:
Step 1: place dehydrated alcohol to make it to dissolve fully chlorate, form the solution of 0.01mol/L;
Step 2: the TETRADECONIC ACID powder is dispersed in the above-mentioned solution under the condition of magnetic agitation, makes it to mix the electrolytic solution that forms 0.2mol/L; The molar mass of described TETRADECONIC ACID powder is not more than 0.5mol/L;
Step 3: two tinsels are inserted in the electrolytic solution as anode and negative electrode, and the volts DS that loads 5V～30V carries out electrolysis 1min～60min;
Step 4: after electrolysis is finished cathode sheets is taken out in drying at room temperature 1min, powder is evenly sticking to be coated onto on label paper or the adhesive tape with forming on the negative plate to adopt label paper or adhesive tape, obtains super open coat after the compacting.
The super open coat that step 4 obtains is transferred to this coating on the arbitrary objects as required.
Described chlorate is iron(ic) chloride or nickelous chloride.
Described tinsel is stainless steel, aluminium flake or copper sheet.
Beneficial effect
A kind of preparation that the present invention proposes can be pressed the method for the super open coat of micro, be after chlorate is dissolved in dehydrated alcohol fully, under the condition of magnetic agitation, continue to add the TETRADECONIC ACID powder and make it to form the electrolytic solution that mixes, with two arbitrarily the tinsels of size respectively as anode and negative electrode, the electrolysis regular hour under certain voltage, just on negative electrode, form the composite powder of metallic particles and corresponding tetradecanoate, take out at room temperature dry at last, be coated onto on label paper or the adhesive tape after compacting this powder is evenly sticking then, it shows splendid super thin performance.Thereby this is a kind of a kind of method that previously prepared powder coating can be transferred to the super thin characteristic of realization on other objects that proposes first.
The coating of the inventive method preparation has super thin angle and very little roll angle greatly to water.In addition, also it can be affixed on the transfer that can realize super thin performance on other object easily, effectively eliminate the particular requirement of experiment condition and substrate.The inventive method is simple, easy to operate, can repair and super thin stable performance, and do not need special device, the more important thing is that this method only needs several minutes to finish, and is expected to use on a large scale on various engineering materialss.
