| 英文摘要 | Materials technology is currently a great challenge in selective laser sintering (SLS). The development of new method for the preparation of a variety of materials has drawn great attention from both industrial and academic organizations. In this work, we described a simple strategy to prepare polyamide 12 (PA12) microspheres through a modified phase-separation process. The phase separation was conducted by adding ethanol as a poor solvent into a formic acid solution of PA12 pellets with polyvinyl pyrrolidone as a dispersant. The mean diameters of the obtained PA12 microspheres, ranging from tens to hundreds of micrometers, were well controlled by adjusting the amount of ethanol and the phase separation temperature. Further investigation by differential scanning calorimetry demonstrated that the sintering window for PA12, between the onset temperatures of crystallization and melting, was drastically stretched during the microsphere formation process. The PA12 particle size and morphology, together with the wider sintering window of the microspheres, demonstrated that the obtained PA12 powder was suitable for SLS processing. (C) 2015 Elsevier Ltd.
