Problems solved by technology

But at present, this technology is only used to print macroscopic structural objects. No one has proposed to print microscopic (nanoscale) structures through macroscopic methods, and there is no report of using it to print carbon black aggregates and primary particles.

Embodiment 1

[0052]In this experiment, the carbon black was first dispersed by ultrasound, so that the carbon black particles reached the level of primary particles and aggregates, and the carbon black morphology was scanned with Hitachi E-sweep scanning probe to obtain the carbon black morphology map. Then use the software that comes with the scanning probe atomic force microscope to export the topography map, and the data is in .exl format. The .exl data is processed by MATLAB software and converted into a specific format. Then import the data into CAD, draw the shape of carbon black, and then convert it into a solid (.dwg file), and convert the data into a .stl format that can be recognized by the 3D printer through 3dmax. Finally, a magnified entity of the carbon black's microscopic topography is printed. The specific process is as figure 1 shown.

[0053] As an optional way, in the above method, the 3D printing is carried out at room temperature, and the material used is photosensi...

Embodiment 2

[0055] The microscopic morphology enlarged entities of carbon black were prepared according to the following steps:

[0056] 1) Disperse carbon black in absolute ethanol by ultrasonic (0.1mg carbon black, 200ml absolute ethanol), ultrasonic 20min;

[0057] 2) Drop the sonicated carbon black anhydrous ethanol solution on the clean mica sheet and dry it. Put the mica sheet into the sample chamber of the scanning probe microscope and scan it to obtain the microscopic topography of carbon black (nanoscale);

[0058] 3) Convert the microscopic morphology of carbon black from .xqd to .xqt, and then export the .exl data (256×256 points);

[0059] 4) Use MATLAB software to develop a program to process the .exl data:

Abstract

The present invention discloses a method for obtaining the carbon black microscopic morphology enlarging entity through 3D printing. According to the method, based on the inorganic material microscopic carbon black primary particles or aggregates, the carbon black microscopic morphology is printed out through a 3D printer so as to establish the association between the carbon black microscopic morphology and the carbon black macroscopic morphology, ie., the macroscopy and the substantiation of the microscopy are achieved through the 3D printing technology; and the carbon black microscopic morphology picture is made out relying on the accurate data points, wherein the real data is adopted as the support, such that the obtained entity has the accurate structure. According to the present invention, the carbon black microscopic morphology is subjected to macroscopy so as to substantially promote scientific research workers to research on the carbon black structure, the particle size and the morphology, and further provide the first-hand data for the research on the carbon black aggregate reinforced rubber, and the development of the technology provides the guidance significance for the actual production.

Description

technical field [0001] The invention relates to the technology of transforming the microscopic appearance of carbon black into a macroscopic entity, and belongs to the technology of studying the microscopic appearance of nano new materials. technical background [0002] The microscopic morphology of carbon black is generally obtained by scanning probe microscope or transmission electron microscope, which is just a topographical map, which cannot be converted into an accurate physical appearance at present. The carbon black models that appear on the market are only based on microscopic topographical maps or conjectures. Drawn, which cannot avoid human subjective factors. [0003] At present, 3D printing technology is in the ascendant, and its application in the field of material preparation is becoming more and more extensive. The paper The 3D printing of gelatin methacrylamide cell-laden tissue-engineered constructs with high cell viability published in the journal Biomater...
