研究了渗流阈值以下不同金掺杂浓度的氟碳聚合物薄膜中丙酮的溶胀行为。聚合物中金团簇的存在改善了聚合物与丙酮之间的混合，而丙酮不是此类聚合物的良好溶剂。为了解释我们的结果，我们研究了聚合物-金属体系的化学计量和形态，并发展了一个修正的Flory-Huggins模型。
We have investigated the swelling of acetone in fluorocarbon polymer films doped with different gold concentrations below the percolation threshold. The presence of the gold clusters in the polymer improves the mixing between the polymer and the acetone, which is not a good solvent for this kind of polymer. To explain our results, the stoichiometry and the morphology of the polymer–metal system have been studied and a modified Flory–Huggins model has been developed.
