由于短链全氟烷基的非结晶特性，使用短链全氟烷基稳定低表面自由能聚合物一直是一项具有挑战性的任务。本研究制备了一系列无规共聚物聚(全氟己基甲基丙烯酸乙酯)-共聚(丙烯酸硬脂酯)(P13FMA-co-PSA)和嵌段共聚物聚(全氟己基乙基甲基丙烯酸酯)-b-聚(丙烯酸硬脂酯)(P13FMA-b-PSA),并系统研究了含氟共聚物的序列结构和13FMA含量对表面自由能和表面活性的影响。重组。静态/动态接触角测角和拒水/拒油分析表明，无规聚合物P13FMA-co-PSA无法同时实现低表面自由能和低表面重组。相比之下，嵌段共聚物P13FMA-b-PSA同时获得了低表面自由能和低表面重组。 X射线光电子能谱（XPS）、动态接触角测角法和差示扫描量热法（DSC）的结果揭示了上述性质。连续的13FMA链段提高了表面氟密度，而连续的SA链则增强了SA链段的结晶度，并进一步阻碍了全氟烷基的表面重组。因此，P13FMA-b-PSA比P13FMA-co-PSA表现出更高的氟原子利用效率和更好的结构稳定性。
Due to the non-crystalline properties of short chain perfluoroalkyl groups, using short chain perfluoroalkyl to stabilize low surface free energy polymers has been a challenging task. In this study, we prepare a series of random copolymers poly(perfluorohexylethyl methacrylate)-co-poly(stearyl acrylate) (P13FMA-co-PSA) and block copolymers poly(perfluorohexylethyl methacrylate)-b-poly(stearyl acrylate) (P13FMA-b-PSA), and systematically investigate the effects of the sequence structure and the content of 13FMA of the fluorinated copolymers on surface free energy and surface reorganization. Static/dynamic contact angle goniometry and water/oil repellency analyses demonstrate that the random polymer P13FMA-co-PSA could not achieve low surface free energy and low surface reorganization at the same time. In contrast, for the block copolymer P13FMA-b-PSA, both low surface free energy and low surface reorganization are acquired simultaneously. The results of X-ray photoelectron spectroscopy (XPS), dynamic contact angle goniometry and differential scanning calorimetry (DSC) reveal the above-mentioned properties. The consecutive 13FMA segments improve the surface fluorine density, while the consecutive SA chains enhance the crystallinity of the SA segments, and further hinder the surface reorganization of the perfluoroalkyl groups. Therefore, P13FMA-b-PSA exhibits a higher utilization efficiency of fluorine atoms and a better structural stability than P13FMA-co-PSA.
