Wide application of nanomaterials as additives

Nanomaterials have the characteristics of volume effect, surface effect, quantum tunnel and quantum size effect, etc., and have wide application prospects in all walks of life. Among them, an excellent application of nanomaterials is as an additive, applied to many fields such as oil, paint, electrolyte, and new energy batteries to improve the application performance and use effect of products.

In the field of new energy batteries, nanomaterials, especially nano-alumina or nano-titanium dioxide, when they are added to the electrolyte with lithium hexafluorophosphate as the main body, the characteristics of nanomaterials can be used to reduce the content of hydrofluoric acid in the electrolyte and reduce the reaction between hydrofluoric acid and the active substance of the electrode, thereby improving the stability of the electrolyte and improving the performance of lithium-ion batteries. In addition, nanomaterials can also be added to electrode materials and diaphragm materials to increase battery life and improve battery capacity, stability and safety.

In the field of coatings, adding nano-titanium dioxide, nano-alumina and other nanomaterials to various coatings, emulsions and resins can develop new coatings with special functions, and promote the coating layer to have special self-cleaning, anti-ultraviolet, anti-bacterial, wear-resistant and other properties.

In the field of lubricants and oil additives, approximately spherical nanoparticles can play a role similar to miniature "ball bearings", which can improve the lubrication performance of the friction surface and reduce friction and wear. For example, there are many reports that the use of surface-modified nano-titanium dioxide as a lubricant additive can improve the anti-wear and anti-friction properties.

In the future, with the improvement of people's living standards and the continuous progress of science and technology, the application of nanomaterials as additives will increase on a large scale, and the application field will be more extensive.
