纳米结构单元的可控自组装可以提供一种合成具有优异性能的新型材料的有效方法。通过辅助手段自组装纳米晶体正在成为一个非常活跃的研究领域，因为它提供了一种生产大规模先进功能材料的方法，在能源，电子，光学和生物领域具有潜在的应用。在这项研究中，我们采用了一种有效的策略，即使用“压力控制”的组装银硫化物（Ag2S）纳米球的直径约为33 nm的大规模，均匀的Ag2S亚微球的大小约为0.33 μm。更重要的是，该策略实现了整个反应系统的在线控制，包括压力，反应时间和温度，也可以用于工业规模上容易地制备其他功能材料。此外，还研究了二乙基二硫代氨基甲酸银（Ag（DDTC））热分解的热力学和动力学参数，探讨了Ag2S纳米结构块的形成机理，并将其组装成均匀的亚微米级结构.作为一种通过纳米颗粒的压力控制自组装来生产亚微米Ag2S颗粒的方法，我们预见这种策略是一种有效且普遍适用的选择，用于构建其他新的构建模块并在工业规模上组装新型和大型功能性微材料。
The controllable self-assembly of nanosized building blocks into larger specific structures can provide an efficient method of synthesizing novel materials with excellent properties. The self-assembly of nanocrystals by assisted means is becoming an extremely active area of research, because it provides a method of producing large-scale advanced functional materials with potential applications in the areas of energy, electronics, optics, and biologics. In this study, we applied an efficient strategy, namely, the use of ‘pressure control’ to the assembly of silver sulfide (Ag2S) nanospheres with a diameter of approximately 33 nm into large-scale, uniform Ag2S sub-microspheres with a size of about 0.33 μm. More importantly, this strategy realizes the online control of the overall reaction system, including the pressure, reaction time, and temperature, and could also be used to easily fabricate other functional materials on an industrial scale. Moreover, the thermodynamics and kinetics parameters for the thermal decomposition of silver diethyldithiocarbamate (Ag(DDTC)) are also investigated to explore the formation mechanism of the Ag2S nanosized building blocks which can be assembled into uniform sub-micron scale architecture. As a method of producing sub-micron Ag2S particles by means of the pressure-controlled self-assembly of nanoparticles, we foresee this strategy being an efficient and universally applicable option for constructing other new building blocks and assembling novel and large functional micromaterials on an industrial scale.
