Nano diaphragm technology improves the performance of waterproof materials

defects on plastic substrates, such as pinholes, cracks and grain boundaries, will lead to the so-called "pore effect", in which oxygen and water molecules can penetrate and penetrate the plastic barrier and enter the active material. However, in applications such as flexible OLED displays, organic solar cells, and even electrophoretic displays, they are highly sensitive to oxygen and moisture, because it is related to the life of the equipment. This means that in order for commercial products to have a long enough life, we must try to block the path of oxygen and water entering the active layer

current isolation technologies focus on using organic or inorganic multilayer coating on plastics to reduce these defects. In contrast, Tera barrier has taken a more innovative approach. The company uses nanoparticles to "plug" these defects in the barrier oxide film to solve the pore effect problem. In its unique nano engineering barrier stack due to excessive deformation, the number of barrier layers required can be reduced to 2 when constructing the barrier. The barrier stack of tera barrier is composed of barrier oxide layer and nano particle sealing layer. Nanoparticles used in barrier films have dual functions, which can not only seal defects, but also block water and oxygen

as a result, the moisture resistance is better than g/y, which is said to meet the most stringent requirements for flexible organic equipment substrates. At 60 ℃ and 90% RH for your reference (that is, the time required for water molecules to pass through the barrier membrane under these conditions), the hysteresis period of the barrier membrane exceeds 2300 hours

however, the barrier layer itself is not the only way for active materials to block oxygen and water. Without adequate sealing, moisture can also penetrate from the side of the equipment. Therefore, the new generation of electronic equipment needs higher efficiency sealant

at present, there are two companies developing this adhesive: Henkel and Delo. Henkel mainly provides heat curing solutions, while Delo focuses on UV curing adhesives

when seeking a balance between better penetration and flexibility, designers must make more trade-offs. The characteristics demanded by the adhesive include better waterproof performance, but also more rigidity, which will affect the flexibility of the final product. Therefore, at present, many research and development efforts are focused on achieving a good compromise between penetration and flexibility, which is to solve the two traditional problems of industrial production at a higher level, namely, increasing output and reducing cost.
