摘要

对电力的迫切需求需要更安全的能源运输。以 AgI 为基础的气象改良剂通常被用来促进冰核形成并消除不良的釉状结冰，从而抑制自然灾害的负面影响。然而，AgI 的内在成核能力严格限制了其进一步的改进。在此，我们在 AgI 基制剂中添加了六方 BiI3。BiI3 与前体的化学作用优化了聚合物复合材料的结晶，从而形成了取向复合网络。此外，BiI3 还能改变燃烧产物的结构和形态，从而产生更多可能的异质核点。结果表明，BiI3 改性的 AgI 基气候改良剂的冰成核率为 1014，是不含 AgI-BiI3 的样品的近 10 倍，与 AgI 样品相比，除冰效率提高了 71.21%。我们的研究结果表明，BiI3 掺杂剂能有效改善天气变化应用中的成核和除冰性能。

Improved composite network via bismuth iodide for efficient ice-nucleating application

The urgent demand for electricity requires more safe energy transportation. AgI-based weather modification agents are commonly employed to facilitate ice nucleation and remove the undesirable glaze icing to suppress the negative effects of natural disasters. However, the intrinsic nucleation potency of AgI strictly limits its further improvement. Here, a hexagonal BiI₃ was added in AgI-based agents. The chemical interactions of BiI₃ and precursors optimize the crystallization of the polymer composite, leading to an oriented composite network. In addition, BiI₃ could alter the structure and morphology of the combustion products, therefore creating more possible heterogeneous nuclei sites. The resultant BiI₃-modified AgI-based weather modification agent exhibits an ice nucleation ∼ 10¹⁴, which is nearly ten times higher than the sample without AgI-BiI₃, leading to a 71.21 % enhancement of deicing efficiency compared to AgI sample. Our results indicate the effectiveness of BiI₃ dopant to improve both nucleation and deicing performance for weather modification applications.

期刊介绍： The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results. Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
