Abstract Polypyrrole, poly( N -methyl pyrrole) and poly( N -ethyl pyrrole) grains were synthesized by aqueous chemical oxidative polymerization in the presence of sodium dodecyl sulfate as both a dopant and a hydrophobizing agent. The resulting grain products were characterized in terms of their size, morphology, surface and bulk chemical compositions, hydrophilic–hydrophobic balance, (photo)thermal property, and conductivity. Scanning electron microscopy studies indicated that the grains were aggregates of atypical particles with submicrometer size. Elemental microanalysis and thermogravimetric analysis confirmed the production of dodecyl sulfate-doped polypyrrole, poly( N -methyl pyrrole) and poly( N -ethyl pyrrole) materials, and they showed near-infrared light-to-heat photothermal properties, which was confirmed by thermography. The data obtained through X-ray photoelectron spectroscopy indicated the presence of dodecyl sulfate dopants on the surface of the grains. The dried polypyrrole and poly( N -ethyl pyrrole) grains showed hydrophobic character, and therefore, they can adsorb to the air–water interface and act as a light-responsive liquid marble stabilizer. Locomotion of the liquid marble can be driven by near-infrared laser irradiation-induced Marangoni flow on a planar air–water surface. The release of internal liquid can be achieved by controlled disruption of liquid marbles via external stimulus application.

十二烷基硫酸盐掺杂的聚吡咯衍生物颗粒作为光响应液体大理石稳定剂

摘要 在作为掺杂剂和疏水剂的十二烷基硫酸钠存在下，通过水性化学氧化聚合合成了聚吡咯、聚（N-甲基吡咯）和聚（N-乙基吡咯）颗粒。所得谷物产品的特征在于它们的尺寸、形态、表面和整体化学成分、亲水-疏水平衡、（光）热性能和电导率。扫描电子显微镜研究表明，这些颗粒是亚微米尺寸的非典型颗粒的聚集体。元素微量分析和热重分析证实了十二烷基硫酸盐掺杂的聚吡咯、聚（N-甲基吡咯）和聚（N-乙基吡咯）材料的产生，它们表现出近红外光热光热性能，这证实了热成像。通过 X 射线光电子能谱获得的数据表明颗粒表面存在十二烷基硫酸盐掺杂剂。干燥的聚吡咯和聚（N-乙基吡咯）颗粒表现出疏水性，因此，它们可以吸附到空气-水界面并作为光响应液体大理石稳定剂。液态大理石的运动可以通过近红外激光辐射诱导的 Marangoni 流在平面空气 - 水面上驱动。内部液体的释放可以通过外部刺激应用控制液体弹珠的破裂来实现。在作为掺杂剂和疏水剂的十二烷基硫酸钠存在下，通过水性化学氧化聚合合成聚吡咯和聚（N-烷基吡咯）颗粒。干燥的聚吡咯和聚（N-乙基吡咯）颗粒表现出疏水特性，可以作为光响应液体大理石稳定剂。液态大理石的运动可以通过近红外激光辐射诱导的 Marangoni 流在平面空气 - 水面上驱动。此外，内部液体的释放可以通过外部刺激应用控制液体弹珠的破坏来实现。
