Smectic liquid crystalline elastomers (SLCE) represent unique materials that combine a 1-D molecular lattice arrangement and orientational order with rubber-elasticity mediated by a polymer network. Such materials may exhibit large thermo-mechanical, opto-mechanical and electro-mechanical effects, due to the coupling of macroscopic sample geometry and microscopic structural features. It is shown that the molecular layer dimensions in the smectic phases can be influenced reversibly by macroscopic strain of the material. We present a microscopic model on the basis of experimental results obtained by mechanical dilatation measurements, optical interferometry, X-ray scattering, (13)C NMR, FTIR and polarizing microscopy data. The model gives an explanation of the controversial results obtained in different types of smectic elastomers.
近晶型液晶弹性体（SLCE）是一类独特的材料，它将一维分子晶格排列和取向有序性与由聚合物网络介导的橡胶弹性相结合。由于宏观样品几何形状与微观结构特征的耦合，这类材料可能会表现出较大的热机械、光机械和机电效应。结果表明，近晶相中的分子层尺寸会受到材料宏观应变的可逆影响。我们基于通过机械膨胀测量、光学干涉测量、X射线散射、（13）C核磁共振、傅里叶变换红外光谱和偏光显微镜数据获得的实验结果，提出了一个微观模型。该模型解释了在不同类型的近晶弹性体中所获得的有争议的结果。
