Abstract

Utilizing the unique properties of fluorine substitution is an effective strategy for constructing highly functional materials. Here, we synthesized a novel copolymer composed of [1.1.1]propellane and perfluoro(propyl vinyl ether) (PPVE), rich in alternating sequences. The spin-coated copolymer film was amorphous, and its surface exhibited an extremely low surface free energy (γ). The γ value was lower than that of polytetrafluoroethylene despite containing only 40 mol % PPVE units. This can be attributed to the cancellation of the C-F dipole moments by the entirely random orientation of the fluorine units.

1.1.1]Propellane 与全氟乙烯基醚的高度交替共聚物：形成氟单体含量小于 50% 的疏水疏油表面。

利用氟取代的独特性质是构建高功能材料的有效策略。在这里，我们合成了一种由富含交替序列的[1.1.1]丙烷和全氟（丙基乙烯基醚）（PPVE）组成的新型共聚物。旋涂共聚物薄膜是无定形的，其表面表现出极低的表面自由能（γ）。尽管 PPVE 单元的含量仅为 40 摩尔%，但其 γ 值却低于聚四氟乙烯。这可归因于氟单元的完全随机取向抵消了 C-F 偶极矩。

期刊介绍： ACS Macro Letters publishes research in all areas of contemporary soft matter science in which macromolecules play a key role, including nanotechnology, self-assembly, supramolecular chemistry, biomaterials, energy generation and storage, and renewable/sustainable materials. Submissions to ACS Macro Letters should justify clearly the rapid disclosure of the key elements of the study. The scope of the journal includes high-impact research of broad interest in all areas of polymer science and engineering, including cross-disciplinary research that interfaces with polymer science. With the launch of ACS Macro Letters, all Communications that were formerly published in Macromolecules and Biomacromolecules will be published as Letters in ACS Macro Letters.
