非理想支化聚合物和理想无支化聚合物的限制自由能相同
The confinement free energies of non-ideal branched polymers and ideal unbranched polymers are the same
摘要:
我们使用降维的方法表明,排除体积相互作用限制在两个平板之间的支化聚合物,在热力学极限,限制自由能和密度分布是相同的理想的线性聚合物具有相同数量的单体和相同的单体板相互作用潜力。由于支化引起的冷凝被由于排除的体积相互作用引起的溶胀精确地补偿。
英文摘要:
We use the method of dimensional reduction to show that a branching polymer with excluded volume interaction confined between two flat plates has, in the thermodynamic limit, a confinement free energy and density profile that is the same as that of an ideal linear polymer with the same number of monomers and the same monomer-plate interaction potential. Condensation due to branching is exactly compensated by swelling due to excluded volume interaction.
