The results indicate that all these fluoropolymer have extremely high surface activity and amazing chemical stability. For example, 0.4KPEGF3 can reduce the surface tension of water solution from 72.8 mN/m to 12.5mN/m, whose CMC was as low as 0.2mg/ml.
研究结果表明,这类氟碳聚合物具有极高的表面活性以及良好的热稳定性和酸碱稳定性,其中0.4KPEGF3的表面活性最高,可使水的表面张力从72.8mN/m最低降至12.5mN/m,其临界胶束浓度(CMC)值仅为0.2mg/ml。
