Embodiment 1
[0042] In this embodiment, the schematic diagram of the block material structure is as follows figure 1 As shown, it is a three-dimensional cube structure composed of several carbon tubes, each dimension of the cube is 1 cm, and the tube walls of the carbon tubes are gathered together.
[0043] Such as figure 1 As shown, the material of each carbon tube is carbon, and each carbon tube is a hollow columnar structure with an open end. The cross section of each columnar structure is circular. The diameter of each carbon tube is 260 micrometers.
[0044] The bulk material was prepared by the template method, as follows:
[0045] Using 3D printing materials as templates, bulk porous carbon materials with special wetting anisotropy were prepared by template method. The specific process is as follows:
[0046] (1) Polycarbonate (PC) is used as the 3D printing material, and the polymer template is made by 3D printing. The structure of the polymer template is the same as that of ...
Embodiment 2
[0053] In this example, the bulk material such as Figure 6 As shown, it is a three-dimensional cube structure composed of several carbon tubes, each dimension of the cube is 1 cm, and the tube walls of the carbon tubes are gathered together.
[0054] Such as figure 1 As shown, the material of each carbon tube is carbon, and each carbon tube is a hollow columnar structure with an open end. The cross section of each columnar structure is circular. The diameter of each carbon tube is 260 micrometers.
[0055] Such as Figure 6 As shown, the material of each carbon tube is carbon, and each carbon tube is a hollow columnar structure with an open end. Moreover, the tube wall of the outermost carbon tube has an opening structure along the length direction of the tube body, that is, the cross section of the outermost carbon tube perpendicular to the length direction of the carbon tube is an arc. Except for the outermost carbon tubes, the cross-sections of the rest of the carbon ...
Embodiment 3
[0064] In this embodiment, the block material is basically the same as the block structure in Embodiment 2, the difference is as Figure 11 As shown, each tube wall has a number of holes, and the size of each hole is in the range of 2 microns to 50 microns, and these holes form channels connecting the carbon tubes.
[0065] The preparation method of the bulk material is basically the same as that in Example 2, except that in step (1), the tube walls of each tubular structure in the template are set as Figure 11 A number of pores shown in , each pore size ranging from 2 microns to 50 microns, form channels communicating with each tubular structure.
[0066] The wettability test of the block material prepared above is as follows:
[0067] (1) Drop water onto the tube wall side of the aggregated carbon tubes, and the measured contact angle is 113.52°.
[0068] (2) Water drops are dropped onto the end face side of the aggregated carbon tubes, and the contact angle is measured t...
