Partial replacement of fluoroacrylates in the monomer composition is able to reduce the free energy of polymer-stabilized blue phase liquid crystal (PSBPLC) due to their low surface tension. The ease of blue phase platelet texture formation is observed under fast cooling and short annealing time before UV irradiation The peak driving voltages are dramatically decreased from 9% to 16% in the resulting PSBPLCs. In addition, the hysteresis is completely suppressed in the PSBPLC containing 3FM-M1. The other PSBPLC containing fluoroacrylates retain very small hysteresis (ΔV < 0.8 V) regardless the fluorine atom numbers In comparison with current PSBPLCs, the fluoroacrylates serve as mesophase enhancer not only to promote the blue phase formation but also to improve the electro-optical properties. This study involved multiple reactions and reactants, such as 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3Recommanded Product: 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate).
1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate
