接枝梳型高分子的SCF理论模拟

利用Scheutjens—Fleer自洽场（SF—SCF）理论，对表面接枝梳型高分子的体系进行模拟研究。模拟结果表明，柔性梳型高分子主链的链段密度分布仅与支链的总链段数有关，主链随支链链段数目的增加而伸展。当总链段数一定且主链长度相同时，线性高分子表现出较高的接枝率，比接枝的梳型高分子具有更大的分子伸展程度与更厚的接枝层。对于线性高分子的接枝层，提高链长比提高接枝率能得到更厚的接枝层。

A Self-Consistent Field Theory Approach on the Grafted Comb Polymers

In this work, on the basis of the SF-SCF theory, we simulated the grafted comb polymer. The results showed that the segment density of the soft trunk chain is only relative to the number of branch. The trunk chains stretch with the increase in the segment density of branch chains. Under the condition of the same total segments, the liner polymer appears a larger graft density and shows more stretchable configuration than the comb polymer. As for the grafted linear polymer, in comparison with the enhancement of the graft density, the increase of the chain length can result in a thicker graft layer.
