摘要
作为助表面活性剂,直链醇在层状溶致液晶的制备中是非常重要的。本文以层状液晶的相行为和小角度X射线衍射测量,研究了直链醇链长对层状液晶结构与稳定的影响。
The measurements of low angle X-ray diffraction showed that the degression of d_0 of lamellar liquid crystal with increase of weight ratio of C_nOH/SDS decreased with increase of the carbon chain length of alcohol used aseosurfactant. The values of d_0 increased with carbon number of alcohol n at certain weight ratio of C_nOH/SDS. The increase of interlayer spacing d with n was related with the increase of d_0 and the decrease of solvent penetration in lamellar liquid crystal under the conditione of weight ratio of C_nOH/SDS and water content. Both the measurements of low angle X-ray diffraction and the phase diagram behavior showed that the stability of lamellar liquid crystal inereased with the chain length of alcohol.
