英文摘要 | The optical properties in steady state and applying shear on a lyotropic cholesteric liquidcrystalline of concentrated aqueous solutions of hydroxypropylcellulose (HPC) have beenstudied. The results reveal that the iridescent of concentrated HPC in water will shift to blueend along with increasing of vision angle or shear rate. A theoretical model including shearorientation by a tilting of the helical axes is proposed in order to interpret the observedphenomena. |
