General description

4'-戊基-4-联苯甲腈(5CB)是向列型液晶。 5CB分别在18oC和35oC下经历从晶体到向列的相变,然后到各向同性状态。 它可以通过改性联苯来生产

Application

用氧化还原活性表面活性剂将 5CB 固定在水-液晶界面上进行了研究。

For nematic liquid crystals (LCs), a disclination line is formed when the director of the LCs changes abruptly. In this study, we demonstrate an approach to form dynamic disclination lines by flowing the nematic liquid crystal 4-cyano-4'-pentylbiphenyl (5CB) in rectangular

Resistive pressure sensors generally employ microstructures such as pores and pyramids in the active layer or on the electrodes to reduce the Young’s modulus and improve the sensitivity. However, such pressure sensors always exhibit complex fabrication process and have difficulties
