Shen, Wenbo; Du, Bin; Liu, Jiaoshi; Zhuo, Haitao; Yang, Chuluo; Chen, Shaojun published an article in 2021. The article was titled 《A facile approach for the preparation of liquid crystalline polyurethane for light-responsive actuator films with self-healing performance》, and you may find the article in Materials Chemistry Frontiers.HPLC of Formula: 627-18-9 The information in the text is summarized as follows:
In this study, liquid crystalline polyurethane was prepared by quaternization between ordinary polyurethane and mesogenic monomers. Meanwhile, a fast light-responsive actuator film with self-healing performance based on liquid crystalline polyurethane was successfully fabricated. In the film, the mesogenic units of the nematic compound were grafted on the polyurethane main chain, leading to liquid crystal phase of the polymer. The photoresponsive units of the liquid crystalline azobenzene were utilized as photosensitive components, and polyurethane was employed as the polymer matrix to endow the material with good film-forming and mech. properties. The as-obtained actuator film not only showed a quick response and large shape deformation upon UV-irradiation but also exhibited temperature-induced self-healing performance. Moreover, the as-prepared light-responsive actuator film exhibited excellent properties coupled with easy fabrication, low cost, and good film-forming and relevant mech. properties, showing promise for future practical applications in photo-driven and optomech. devices.3-Bromopropan-1-ol(cas: 627-18-9HPLC of Formula: 627-18-9) was used in this study.
3-Bromopropan-1-ol(cas: 627-18-9) is used in the synthesis of fluorescent halide-sensitive quinolinium dyes, chiral, quaternary prolines through cyclization of quaternary amino acids and molten salt-polymers. It is utilized for the study of micellar media and in microemulsions based on cationic or a nonionic surfactant by reacting with phenols.HPLC of Formula: 627-18-9
