提出了把聚合物溶液的总熵分解为位置熵和构象熵。前者可以解析地用Flory-Huggins公式表示;后者可以利用简单立方格子无规自避行走多链体系模型进行模拟,计算表明构象熵和混合热都很好地遵守标度定律。
It is proposed to decompose the total entropy of polymer solution into position entropy and conformational entropy. The former can be analytically represented by the Flory-Huggins formula, which can be modeled using a simple cubic lattice random self-walking multi-chain system model, which shows that both the conformational entropy and the heat of mixing comply well with the scaling law.
