Description
Technical field
The present invention relates to carbon black microscopic appearance and be converted into macroscopical entity technology, belong to research nanometer new material microscopic appearance technology.
Technical background
Carbon black microscopic appearance generally obtains with scanning probe microscopy or transmission electron microscope, a just shape appearance figure, also cannot be converted into accurate pattern entity at present, the carbon black model that market occurs only draws according to microscopic appearance figure or guess, and this can not be avoided artificial subjective factor.
At present, 3D printing technique is in the ascendant, increasingly extensive in the application of field of material preparation.The paper The 3D printing of gelatin methacrylamide cell-laden tissue-engineered constructs with high cell viability that the people such as Billiet T deliver on Biomaterials periodical take acrylamide gel as raw material, has printed mechanics of biological tissue.This structure can load cell, and this institutional framework that the survival rate 97%, 3D of its cell prints and cell have good compatibility.The paper 3D printing of cell-laden constructs for heterogeneous tissue regeneration that the people such as Pati F deliver on Manufacturing Letters periodical have employed similar method 3D and has printed regeneration isomery tissue, and the survival rate of its cell is also very high.But current this technology is all the structural objects for printing macroscopic view, and also nobody proposes the structure being printed microcosmic (nanoscale) by the method for macroscopic view, does not more use it for the report printing carbon black aggregate, primary particle.
Summary of the invention
For the problems referred to above, the invention provides a kind of method being printed acquisition carbon black microscopic appearance amplifying entity by 3D.For inorganic material microcosmic carbon black primary particle or aggregation, printed the microscopic appearance of carbon black by 3D printer, establish the contact of carbon black pattern micro-mobility protocols, namely achieved by 3D printing technique and microcosmic is carried out macroscopic view, hypostazation.
The present invention is achieved through the following technical solutions:
Printed the method obtaining carbon black microscopic appearance amplifying entity by 3D, comprise the following steps:
1) the microscopic appearance figure of carbon black is obtained;
2) described microscopic appearance figure is converted to the data file representing each point coordinate value in described microscopic appearance figure;
3) by step 2) in the data file transition of gained become the discernible form of mapping software;
4) by step 3) in the data importing mapping software of gained draw out each independently point, then hypostazation is carried out to these points, obtains the 3D solid picture amplified;
5) 3dmax software is adopted to convert the 3D solid picture of gained in step 4 to 3D printer discernible form;
6) amplifying entity that 3D printer prints performance carbon black microscopic appearance structure is opened.
This method achieves carbon black microscopic appearance amplifying entity by 3D printing technique, and rely on accurate data point to make carbon black microscopic appearance figure, have True Data as support, gained amplifying entity structure is accurate.
Alternately, in the above-mentioned methods, the microscopic appearance figure in described step 1) adopts scanning probe microscopy or transmission electron microscope to obtain.
Alternately, in the above-mentioned methods, by ultrasonic carbon black dispersion in absolute ethyl alcohol, ultrasonic 20min; Then ultrasonic good carbon black ethanol solution is dropped on clean mica sheet, dry up, mica sheet is put into scanning probe microscopy sample room, scans, obtain carbon black microscopic appearance figure.Wherein the mixing ratio of carbon black and absolute ethyl alcohol is preferably carbon black 0.1mg, absolute ethyl alcohol 200ml.
Alternately, in the above-mentioned methods, described step 2) obtain the software that carries of instrument by microscopic appearance used in step 1) and complete, such as carry software by scanning probe microscopy and be converted into Excel data, the number of data point can be chosen according to the requirement of image resolution ratio flexibly (when data provide more, image resolution ratio is higher), optional data point number comprises: 64 × 64,128 × 128,256 × 256,512 × 512,1024 × 1024 etc.Preferably 256 × 256 points.
Alternately, in the above-mentioned methods, described step 3) and 4) described in mapping software be AutoCAD.
Alternately, in the above-mentioned methods, described step 3) to be specially each coordinate value of each point between space change comma into.Concrete conversion regime can adopt MATLAB software, carries out according to following program:
