polyester-based liquid crystalling ionmer containing sulfonate group - Introduction
Polyester-based liquid crystalline ionomers containing sulfonate groups have many important properties and uses. The following is a description of its nature, use, preparation and safety information:
Nature:
1. Liquid crystal characteristics: this kind of polyester has a liquid crystal phase, that is, in a certain temperature range, the molecules show an orderly arrangement, while maintaining liquidity.
2. Thermal stability: due to the special structure of sulfonate polyester, it has good thermal stability and high temperature resistance.
3. Electrical properties: These polymers usually exhibit excellent electrical properties, with good dielectric constants and low dielectric losses.
4. Adjustability: By changing the chemical structure of polyester and adding other functional monomers, the optical properties, electrical properties and thermal properties of polyester can be controlled.
Use:
1. Liquid Crystal Display: this kind of polymer is often used in the preparation of liquid crystal display (LCD), as a carrier material or liquid crystal control layer, to achieve the adjustment of optical and electrical properties.
2. Electronic devices: Sulfonate polyester can also be used in the preparation of other electronic devices, such as resistors and capacitors.
3. Functional films: Due to their excellent optical properties, these polymers can be used to prepare coating films, optical films, etc.
Preparation Method:
The common preparation method is to synthesize Sulfonate-based polyester liquid crystal ionomer through polycondensation reaction. First, appropriate acid anhydride and sulfonic acid ester monomers are selected and polycondensed by a polyesterification reaction to obtain a polymer.
Safety Information:
1. This kind of polymer is usually stable and harmless under ordinary conditions, but it may decompose under high temperature, high pressure or other extreme conditions to produce harmful substances. Therefore, in the operation and processing should pay attention to safety protection.
2. In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical help.
3. Please refer to the Safety Data Sheet (MSDS) and relevant regulations for proper storage, handling and transportation of Sulfonate-based polyester liquid crystal ionomers.
