摘要

利用前人提出的多孔介质中各向异性流体的广义范德华方程来描述多孔介质对多肽溶液相行为的影响。通过引入势阱深度的温度依赖性和球柱的几何参数，再现了多肽聚γ-苄基- l-谷氨酸(PBLG)在二甲基甲酰胺溶液中的主要相行为特征，包括两个向列相的存在。结果表明，多孔介质的存在使相图向低密度和低温度区域偏移。

Effects of porous media on the phase behaviour of polypeptide solutions

The generalized van der Waals equation for anisotropic fluids in porous media, proposed by the authors in previous works, is used to describe the effect of porous media on the phase behavior of polypeptide solutions. By introducing the temperature dependence for the depth of the potential well and the geometric parameters of the spherocylinder, the main features of phase behavior of the polypeptide poly (γ-benzyl-L-glutamate) (PBLG) in a solution of dimethylformamide, including the existence of two nematic phases, is reproduced. It is shown that the presence of a porous medium shifts the phase diagram to the region of lower densities and lower temperatures.
