摘要

我的贡献。简要分析了Erukhimovich(1947-2022)对二嵌段和三嵌段共聚物微相分离理论的创立。他的计算多组分聚合物体系相关函数的矩阵方法已被应用于寻找二嵌段共聚物熔体在静电场中的旋量。严格地证明了共聚物的局部介电常数与序参量的线性关系,其旋量条件与没有电场时相同。对于二次相关的更一般情况,计算了对Flory-Huggins参数临界值的修正。

Diblock Copolymer Melt in an Electric Field: Stability of the Homogeneous State in the Random Phase Approximation

Diblock Copolymer Melt in an Electric Field: Stability of the Homogeneous State in the Random Phase Approximation

The contribution of I.Ya. Erukhimovich (1947–2022) to the creation of the theory of microphase separation in di- and triblock copolymers has been briefly analyzed. His matrix method of calculating correlation functions for multicomponent polymer systems has been applied to find the spinodal of a diblock copolymer melt in a static electric field. It has been strictly shown that for a linear dependence of local dielectric constant of the copolymer on the order parameter the spinodal condition remains the same as in the absence of the electric field. The correction to the critical value of the Flory‒Huggins parameter has been calculated for more general case of the quadratic dependence.
