Description

technical field [0001] The invention relates to a carbon nanotube material, in particular to an ultra-light and ultra-buoyant carbon nanotube material, a preparation method and application thereof. Background technique [0002] Buoyancy materials can be used in ships, submarines, underwater pipelines, other mechanical structures, vehicles used in water or water surface environments, and equipment for water treatment. Traditional buoyancy materials mostly use lightweight materials such as foam, but such materials have a relatively low load-bearing capacity and are easily contaminated by oil and the like. [0003] Qin, L. et al. proposed a class of buoyant materials as the supporting legs of bionic water striders (ACS applied materials & interfaces 2014, 6(23), 21355-21362.), the buoyant material is copper doped with TiO2 and dodecanethiol Foam can change its wettability through ultraviolet irradiation, and can float on water and oil, but it can only carry objects 2.6 to 4.5 ...

Problems solved by technology

[0003] Qin, L. et al. proposed a class of buoyant materials as the supporting legs of bionic water striders (ACS applied materials & interfaces 2014, 6(23), 21355-21362.), the buoyant material is copper doped with TiO2 and dodecanethiol Foam can change its wettability through ultraviolet irradiation, and can float on water and oil, but it can only carry objects 2.6 to 4.5 times heavier than itself, and the load capacity is relatively low

[0004] Zhang, J. et al. proposed a buoyancy material using disc-shaped steel sheets coated with amphiphobic substances as the supporting legs of bionic water striders (Langmuir 2014, 30(35), 10637-42.), which can be used on water , n-hexadecane, and vegetable oil float, but it can only carry about 10 times more substances than itself, and the carrying capacity is small

[0005] Xueli Liu. et al proposed a copper oxide-coated copper wire with a micro / nano-scale structure as the supporting leg of the bionic water strider (ACS nano 2012, 5614–5620.), which has super-oleophobic properties at the water-oil interface, But the support force that can bear is only 1000μN at most

[0006] In short, the existing super-buoyancy materials generally have defects such as high material density, low load-carrying ratio, low support force, poor environmental adaptability, and acid and alkali resistance, which need to be improved urgently
