Dodecyl sulfate-doped polypyrrole derivative grains as a light-responsive liquid marble stabilizer
Original language description
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.
