按照现代高分子凝聚态物理学观点,高分子溶液按浓度分为:极稀溶液、稀溶液、亚浓溶液、浓溶液、极浓溶液5个层次,各层次间的分界浓度分别称为动态接触浓度、接触浓度、缠结浓度和全高斯链浓度,其中全高斯链浓度由本文作者命名。文中给出各分界浓度的定义,介绍各分界浓度的物理意义,特别说明命名全高斯链浓度的依据。同时详细讨论了不同浓度溶液中大分子链的构象及其变化、链间相互作用的本质和微观图像、以及溶液浓度变化对溶液性质的影响。
According to modern polymer condensed matter physics point of view, the polymer solution according to the concentration is divided into: very dilute solution, dilute solution, sub-concentrated solution, concentrated solution, very concentrated solution five levels, the demarcation of the levels between the levels were called dynamic contact Concentration, contact concentration, entanglement concentration, and total Gaussian chain concentration, where the total Gaussian chain concentration is given by the author. The definition of each demarcation concentration is given in this paper, and the physical meaning of each demarcation concentration is introduced. In particular, the basis of the named full Gaussian chain concentration is given. At the same time, the conformation and the change of macromolecular chains in different concentration solutions, the essential and microscopic images of the interaction between chains, and the influence of solution concentration on the solution properties were discussed in detail.
