%X Solvent-free oxidative coupling polymerization
of 3-hexylthiophene
using FeCl3 oxidant was conducted to synthesize poly(3-hexylthiophene)
grains. Optical and scanning electron microscopy studies confirmed
production of submillimeter-sized atypical grains with rough surfaces.
Solubility test, Fourier transform infrared spectroscopy, and 1H nuclear magnetic resonance studies indicated the branching
and cross-linking of the poly(3-hexylthiophene). Elemental microanalysis
and X-ray photoelectron spectroscopy studies confirmed that the poly(3-hexylthiophene)
grains were doped with chloride ions. The poly(3-hexylthiophene) grains
showed hydrophobic character due to hexyl side chains, and the critical
surface tension was determined to be 25.9 mN m–1. The poly(3-hexylthiophene) showed a light-to-heat photothermal
property, and near-infrared laser irradiation to the poly(3-hexylthiophene)
grains induced a rapid temperature increase up to 664 °C. The
poly(3-hexylthiophene) grains can work as an effective liquid marble
stabilizer with a photothermal property, and the liquid marble exhibited
locomotion on a water surface due to near-infrared laser-induced Marangoni
flow.
