Prussian blue (PB) is limited in its application by its breakdown at elevated temperatures. To improve the heat resistance of PB, we prepared a composite film comprising PB nanoparticles (NPs), smectite clay, and an organic compound. The composite film had a microstructure in which PB NPs were intercalated between smectite/organic compound layers. The predominant oxidation temperature of the PB NPs in the composite film was around 500 °C in air, higher than the oxidation temperature of bulk PB in air (250 °C). This improvement in the oxidation temperature may be due to the composite film acting as a barrier to oxygen gas. These results indicate the effectiveness of clay materials for the improvement of heat resistance for low-temperature decomposition compounds, not only PB but also other porous coordination polymers.

蒙脱土和ε-己内酰胺组成的粘土膜中普鲁士蓝纳米颗粒耐热性的提高

普鲁士蓝(PB)的应用受到高温分解的限制。为了提高PB的耐热性,我们制备了包含PB纳米颗粒(NPs),蒙脱石粘土和有机化合物的复合膜。该复合膜具有微结构,其中PB NPs插在蒙脱石/有机化合物层之间。复合薄膜中PB NP的主要氧化温度在空气中约为500°C,高于空气中大块PB的氧化温度(250°C)。氧化温度的这种改善可能是由于复合膜充当了对氧气的阻挡层。这些结果表明粘土材料对于改善低温分解化合物(不仅是PB,而且是其他多孔配位聚合物)的耐热性的有效性。
