《Effect of external electrical field on phase behavior and morphology development of polymer dispersed liquid crystal》 was written by Yang, Dianzhi; Lin, Jiaping; Li, Tao; Lin, Shaoliang; Tian, Xiaohui. Recommanded Product: 74305-48-9 And the article was included in European Polymer Journal on August 31 ,2004. The article conveys some information:
Phase diagrams for mixtures of liquid crystal (LC)/monomer with and without an external elec. field applied have been established using polarized light microscope (PLM). The (isotropic + nematic) coexistent phase region and (isotropic + isotropic) phase boundary of LC/monomer mixtures were observed to shift upward to higher temperatures when the external elec. field exists. The elec. field applied during the crosslinking polymerization has a significant influence on the phase diagrams for the LC/polymer(E 51) mixtures by rendering the coexistent phase regions shift upward to higher temperatures The influence of the external elec. field on the processes of the isotropic-isotropic phase separation and liquid crystal ordering in PDLC formation has also been investigated. Both the processes could be highly accelerated by the elec. field. In the experiment, the researchers used many compounds, for example, 4-n-Pentylphenyl-4-pentylbenzoate(cas: 74305-48-9Recommanded Product: 74305-48-9)
4-n-Pentylphenyl-4-pentylbenzoate(cas: 74305-48-9) belongs to esters. Esters are more polar than ethers but less polar than alcohols. Recommanded Product: 74305-48-9 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.
