Description
Technical Field
The invention relates to a liquid crystal self-orientation material, in particular to an amphiphilic microsphere material, a preparation method thereof and a display.
Background
The nano particles are added into Vertical Alignment (VA) type liquid crystal, so that the performance of the photoelectric device can be improved, such as the response time is accelerated, the driving voltage is reduced, and the like. However, because the force between the nanoparticles and the substrate is stronger than the force between the nanoparticles and the liquid crystal molecules, the liquid crystal medium added with the nanoparticles is easy to have a phase separation phenomenon, such as oligomeric silsesquioxane (POSS). POSS can form hydrogen bonds with an ITO substrate due to the rich hydroxyl groups, and contributes to the self-orientation of liquid crystal molecules. However, the biggest problem hindering the application of POSS is the poor compatibility with liquid crystal media and the poor acting force between POSS and liquid crystal molecules, so that the stability of POSS is poor and the industrial research is difficult to be further developed.
The amphiphilic nano heterojunction material belongs to Janus particles, and the Janus particles refer to a class of non-centrosymmetric particles with different characteristics. The asymmetry is not limited to the difference of the shapes of the two sides of the particle, but also includes the asymmetry from the chemical composition to the physical properties and performances of the two sides of the particle. The construction of Janus particles greatly enriches the structural diversity and application range of the nanoparticles. When Janus particles have hydrophilicity at one end and hydrophobicity at the other end, the Janus particles can be used as emulsion stabilizers to perform two-phase catalysis. By utilizing the special amphipathy and good interface stability of Janus particles, the material is expected to give consideration to the acting force of the substrate and the acting force between liquid crystal molecules, and a molecular self-alignment photoelectric display is constructed.
In order to combine the forces between the nano material and the substrate and the forces between the nano material and the liquid crystal molecules, a new liquid crystal self-alignment material with special amphipathy and good interface stability is needed.
