Highly oriented, layered, and mech. resilient films of polydopamine (PDA) have been synthesized from the air/water interface. The films show a unique layered structure, as shown by scanning and transmission electron studies (SEM/TEM) and X-ray diffraction anal. (XRD), which resemble that of 2D layered materials. The films exhibit a composition typical of PDA-based materials, as evidenced by XPS; moreover, the samples present the distinctive resonance modes of PDA-based nanomaterials in Raman and IR spectroscopy (FTIR) experiments The presence of highly ordinated 3-4 protomol. stacking, taking place at the air/water interface, with a unique eumelanin-like supramol. arrangement is presented. Moreover, the films show superior mech. resilience with E = 13 ± 4 GPa and H = 0.21 ± 0.03 GPa, as revealed by nanoindentation experiments, making them highly resilient and easily transferable. Finally, the ordering induced by the interface opens many possibilities for further studies, including those regarding the supramol. structure on PDA due to their similarity to 2D layered materials. In the experiment, the researchers used many compounds, for example, 5,6-Dihydroxyindole (cas: 3131-52-0Recommanded Product: 3131-52-0).
5,6-Dihydroxyindole (cas: 3131-52-0) belongs to indole derivatives. In addition to tryptophan, indigo, and indoleacetic acid, numerous compounds obtainable from plant or animal sources contain the indole molecular structure. Due to this activity, the indole ring system has become an important component or intermediate in the synthesis of heterocycles.Recommanded Product: 3131-52-0
