Lanzhou Chemicals Co., Ltd. obtains the interface construction and application of light and heat control smart meters.
Under the support of the National Natural Science Foundation of China, the National Key Basic Research and Development Program ("973" Program), the key deployment projects of the Chinese Academy of Sciences, the "Hundred Talents Program" of the Chinese Academy of Sciences, and the "Light of the West" talent training program, Lanzhou Chemical Physics, Chinese Academy of Sciences Wang Xiaolong and Wang Daoai, research fellows of the State Key Laboratory of Solid Lubrication of Research Institutes, have made progress in the application of photothermal control smart watch interface construction and their applications in anti-icing, friction control, and controlled repair hydrophobicity. Fe3O4 nano-particles have great potential in magnetic resonance imaging, targeted drug delivery, separation, tribology, and photothermotherapy due to their superparamagnetic and high near-infrared photothermal conversion efficiency. The research group prepared Fe3O4 nanoparticles by introducing them into the interface system of coatings, micro-nanogels, etc., utilizing the excellent infrared photothermal effect of Fe3O4 nanoparticles and its controllable interface in situ, rapidly and efficiently. Photothermal regulation responds quickly to smart meter interface materials. The economic and security problems caused by the snow and ice disasters have become increasingly serious, and increasingly serious challenges have been raised for traditional anti-icing methods such as spraying of anti-icing agents, mechanical or thermal de-icing. The research group developed a self-lubricated light-heat anti-icing/deicing coating. The self-lubricant in the coating effectively retards the formation of ice and reduces the adhesion of ice to the surface, while the excellent photothermal effect of the Fe3O4 nanoparticles accelerates the melting of the interfacial ice layer for rapid deicing (Adv. Funct. Mater). 2015, 25, 4237-4245). Inspired by the super-clear surface of the natural world, the research group also prepared a variety of super-hydrophobic surfaces with self-repairing capabilities, and achieved ultraviolet (UV) light, heating, mechanical rubbing, etc. to promote self-repairing surface super-clearance properties (Small 2015, 11 , 426-431; J. Phys. Chem. 2015, 119, 7109-7114; Langmuir 2012, 28, 5845-5849; Chem. Commun. 2011, 47, 2324-2326), but the fastness of damaged super sparse surfaces Repair still faces many problems. The researchers introduced Fe3O4 nanoparticles into the superhydrophobic fabric modified with polydopamine capsules, and used the excellent photothermal effect of Fe3O4 nanoparticles to achieve rapid repair of damaged superhydrophobic surfaces in tens of seconds or even shorter. The long-term stable use of medical materials, self-cleaning surfaces, etc. offers possibilities (J. Mater. Chem. A 2015, 3, 17074-17079). Friction control is closely related to the "design of smart devices" and is the focus of friction workers. It is also a new research hotspot in the field of tribology. It has potential application value in intelligent transmission devices, biosensors, and microfluidics (Adv. Mater). Interfaces 2015, 2, 1400392). In the study of interfacial friction control, the researchers used the near-infrared photothermal effect of Fe3O4 nanoparticles to regulate the frictional transition of the sliding interface. As we all know, there are two important parts influencing the friction of the system. One is the lubrication additive and the other is the sliding interface material. The researchers started with these two points. First, a nanogel containing Fe3O4 was prepared. As a water-lubricant additive, under the irradiation of near-infrared light, interfacial frictional regulation was achieved (ACS Macro Lett. 2016, 5, 144). -148). In addition, a friction interface material containing both a polymer brush and Fe3O4 nanoparticles was designed and prepared to achieve a controllable and efficient transition from low friction to high friction under the control of near-infrared light (Chem. Commun., 2016, 52, 3681-3683).
Polishing Wax/polish compound/polish paste belongs to chemical products and commodities, but in fact it is made by physical mixing and heating. Polishing wax also produces grinding, smoothing, smooth, and bright effects through physical movement during use, thereby playing the role of polishing and polishing. Polishing wax has a wide range of uses. It not only refers to the polishing and polishing of metals, but also the polishing of resins PU,PA, plastics, as well as hardwood furniture and appliances.
Polishing is divided into rough polishing, medium polishing, fine polishing and mirror polishing.For metal utensils and utensils of different materials, it is necessary to choose a suitable polishing wax to play a real role and an ideal effect.
