Abstract

Ammonium nitrate (AN) is an important explosive that is widely used in military and civilian fields. However, the high hygroscopicity of AN limit its wider applications and developments. In this study, AN were coated with Co8HQ complexes via solid–solid method, giving a series of surface modified AN/Co8HQs. AN and AN/Co8HQs were characterized by XRD, FTIR, SEM, and EDS. The water contact angles of AN/Co8HQs are higher than that of AN. Hygroscopicity experiments show that the hygroscopicity of AN/Co8HQs was reduced over 40 % at all tested relative humidities in 24 h. The AN/1.5 %Co8HQ showed a 70 % hygroscopicity drop in 24 h at 97.3 % RH. Micrographs of AN/Co8HQ show that Co8HQ were uniformly coated on the surface of AN and filled the voids of AN. Generally, a straightforward and scalable method is provided to improve the anti-hygroscopic properties of AN, which has a considerable potential for practical applications. This gives AN/Co8HQ a very good anti-hygroscopic property.

易涂布，显著增强AN的抗吸湿特性

硝酸铵是一种重要的炸药，广泛应用于军事和民用领域。然而，AN的高吸湿性限制了其更广泛的应用和发展。本研究采用固-固方法在AN表面涂覆Co8HQ配合物，得到一系列表面改性的AN/Co8HQ。采用XRD、FTIR、SEM和EDS对AN和AN/ co8hq进行了表征。AN/ co8hq的水接触角大于AN。吸湿性实验表明，在所有测试相对湿度下，AN/Co8HQ的吸湿性在24 h内降低了40%以上，在97.3% RH下，AN/ 1.5% Co8HQ的吸湿性在24 h内降低了70%。AN/Co8HQ的显微照片表明，Co8HQ均匀地包裹在AN表面，并填充了AN的空隙。一般来说，提供了一种简单、可扩展的方法来提高AN的抗吸湿性能，具有相当大的实际应用潜力。这使得AN/Co8HQ具有非常好的抗吸湿性能。
