Step 2, the aluminium flake of area load copper nitrate is placed in ceramic vessel, and covers ceramic fragment thereon, It obtains bottom and is successively covered with the aluminium flake of area load copper nitrate and the ceramic vessel of ceramic fragment;
Step 3, the ceramic vessel of aluminium flake and ceramic fragment that bottom is successively covered with to area load copper nitrate is placed in Acetylene at 420-460 DEG C and 20-40h in the mixed atmosphere of argon gas are made in the surface of ceramic vessel and ceramic fragment Carbon nano-fiber film without metallic catalyst.
The further improvement of preparation method as the carbon nano-fiber film without metallic catalyst:
Preferably, the time that aluminium flake immerses in copper nitrate aqueous solution is 20-40min.
Preferably, ceramic vessel is ceramic boat or ceramic bowl or ceramic disk or pottery pot.
Preferably, ceramic fragment is that ceramic bowl fragment or ceramic insulator fragment or ceramic tile fragment or common brick are broken Block or cement concrete fragment.
Preferably, before being warming up to 420-460 DEG C, bottom is first successively covered with to the aluminium flake and ceramics of area load copper nitrate The ceramic vessel of pieces, which is placed in argon atmospher, to heat up.
Preferably, the acetylene and 0.008-0.012L/min that the mixed atmosphere of acetylene and argon gas is 0.08-0.12L/min The mixed gas of argon gas.
Beneficial effect compared with the existing technology is:
First, product made from surface for ceramic vessel and ceramic fragment uses scanning electron microscope, transmission respectively Electronic Speculum and the subsidiary power spectrum tester of scanning electron microscope are characterized, as a result, it can be seen that, product is three-dimensional porous by carbon nanometer The film of fiber composition;Wherein, carbon nano-fiber is polycrystalline structure, and it is free of any metallic catalyst.It is this by carbon nanometer The product that fiber is assembled into, not only due to the speciality of carbon nano-fiber, but also because carbon nano-fiber is polycrystalline structure, due also to carbon nanometer Fiber is free of any metallic catalyst, is more accumulated because of film by a large amount of carbon nano-fiber, and has greatly expanded product Application range.
Second, the carbon nano-fiber film without metallic catalyst has not only been made in preparation method, also there is at low cost, production The characteristics of amount is big, is easy to industrial-scale production can more realize the recycling to various ceramics and building waste, to mitigate Pollution to environment;Product obtained has the characteristics that light-weight, hydrophobic and good mechanical property, is extremely easy to widely business Change and is applied to various oils leakage cleaning field.
