The poor mechanical properties and processability of pristine heterocyclic conductive polymers represent the most notable scientific and technological challenges that have greatly limited the application of these polymers. We report a soft and mechanically processable free-standing pristine polypyrrole (PPy) membrane (PPy-N) that is as soft in liquid nitrogen (−196 °C) as it is at room temperature, despite a glass transition temperature (T_g) above 100 °C. This PPy membrane also displays a highly attractive combination of properties, including mechanical processability, lightweight (9 g m^–2), large surface area (14.5 m² g^–1), stable electrothermal behavior, amphiphilicity, excellent cytocompatibility, and easy synthesis, at virtually any size. This discovery demonstrates an approach to changing the mechanical property of heterocyclic conductive polymer with no chemical alterations or compounding and may enhance the development of inherently conducting polymers for applications in energy storage and biomedicine and as lightweight conducting and heating materials.

液态氮中的导电聚合物波

原始杂环导电聚合物的较差的机械性能和可加工性代表了最显着的科学技术挑战，这些挑战极大地限制了这些聚合物的应用。我们报告了一种柔软且可机械加工的独立原始聚吡咯（PPy）膜（PPy-N），尽管在玻璃态转变温度（T _g）下，它在液氮（-196°C）中和室温下一样柔软。高于100°C。这种PPy膜还显示出极具吸引力的性能组合，包括机械加工性能，轻巧（9 gm ^–2），大表面积（14.5 m ² g ^–1）），几乎任何大小的稳定电热行为，两亲性，出色的细胞相容性和易于合成的特性。该发现证明了一种无需化学改变或配混即可改变杂环导电聚合物机械性能的方法，并且可以增强用于能量存储和生物医学以及用作轻质导电和加热材料的固有导电聚合物的开发。
