Oxygen-SensitiveNanomaterials Synthesized in an OpenSystem: Water-Triggered Nucleation and Its Controllability in theGrowth Process

A novel method has been developed for synthesizing the oxygen-sensitive nanomaterial W₁₈O₄₉, utilizing 1,3-propanediol as a solvent, with water-triggered nucleation and controllable crystal growth in an open system. The amount of water addition was precisely investigated for the effect of the crystal growth process. Furthermore, the incorporation of 2,5-furandicarboxylic acid into the process led to the successful preparation of a functionalized nanocomposite polyester, W₁₈O₄₉/poly­(propylene 2,5-furandicarboxylate) (PTF), through in situ polymerization, exhibiting superior thermal insulation properties.
