采用两种互补的自洽场论方法来分析不同聚合度聚离子的二元和三元刷的平衡结构。预测二元刷中的分层：较短的链完全嵌入近端子层，耗尽较长链的端点，而外围子层仅包含较长链的末端片段。子层之间的边界富含反离子，可以中和近端子层的残余电荷。使用数值 Scheutjens-Fleer 方法对二元刷的这些分析预测进行了确认，并将其扩展到三元刷。
Two complementary self-consistent field theoretical approaches are used to analyze the equilibrium structure of binary and ternary brushes of polyions with different degrees of polymerization. Stratification in binary brushes is predicted: the shorter chains are entirely embedded in the proximal sublayer depleted of end-points of longer chains while the peripheral sublayer contains exclusively terminal segments of longer chains. The boundary between sublayers is enriched with counterions that neutralize the residual charge of the proximal sublayer. These analytical predictions for binary brushes are confirmed and extended to ternary brushes using the numerical Scheutjens-Fleer approach.
