In this study, a novel superhydrophobic nano-aluminum/iron (III) oxide composite has been prepared by a facile one-step process of electrophoretic deposition, with wide potential applications. The optimal suspension included ethanol, acetyl-acetone, and the additives of fluorotriphenylsilane and perfluorodecyltriethoxysilane. The microstructure, wettability, and exothermic performance were analyzed by field emission scanning electron microcopy (FESEM), X-ray diffraction (XRD), water contact angle measurements, and the differential scanning calorimetry (DSC) technique. The water contact angle and the heat-release of the target composites could reach to ~170° and 2.67 kJ/g, and could still keep stable, after exposure for six months, showing a great stability. These results provided an exquisite synthesis of ideas, for designing other superhydrophobic energetic materials with self-cleaning properties, for real industrial application.
在本研究中,通过一种简便的电泳沉积一步法制备了一种新型超疏水纳米铝/三氧化二铁复合材料,具有广泛的潜在应用。最佳悬浮液包括乙醇、乙酰丙酮以及氟代三苯基硅烷和全氟癸基三乙氧基硅烷添加剂。通过场发射扫描电子显微镜(FESEM)、X射线衍射(XRD)、水接触角测量和差示扫描量热法(DSC)技术对微观结构、润湿性和放热性能进行了分析。目标复合材料的水接触角和热释放量可分别达到约170°和2.67 kJ/g,在暴露六个月后仍能保持稳定,显示出良好的稳定性。这些结果为设计其他具有自清洁性能的超疏水含能材料以用于实际工业应用提供了精妙的合成思路。
