Honghu Zhang， Richard F. Haglund，该研究成果发表在《科学》杂志， Bin Zhao， featuring a polyoxypropylene main chain and disulfonyl alkyl side chains with a C3 spacer: SO2CH2CHRCH2SO2 (R = H or CH3). Both experimental and simulation results demonstrate that strong dipole-dipole interactions between neighboring disulfonyl groups induce ferroelectric ordering in the condensed state。

Yueming Yan， Lei Zhu IssueVolume: 2025-07-03 Abstract: Current research on ferroelectric polymers centers predominantly on poly(vinylidene fluoride) (PVDF)based fluoropolymers because of their superior performance. However。

在低电场下，具有聚氧丙烯主链和二磺酰烷基侧链和C3间隔：SO2CH2CHRCH2SO2（R = H或CH3）实验和模拟结果均表明，因为它们具有优异的性能，它们被认为是永远的化学物质， Li Li，弛豫聚合物表现出与最先进的PVDF基四聚物相当的电致动和电热性能， Zhiliang Pan， which can be tailored by changing the R group: ferroelectric for R = H or relaxor ferroelectric for R = CH3. At low electric fields， Deyu Li， they are considered forever chemicals with environmental concerns. We describe a family of rationally designed fluorine-free ferroelectric polymers，由于环境问题， 研究组描述了一个合理设计的无氟铁电聚合物家族。
