摘要 以纳米金刚石为乳化剂,BPO为引发剂,利用Pickering效应成功合成得到了聚苯乙烯/纳米金刚石复合微球。XRD、TDA-DTA、TEM、BET以及FT-IR分别进行了结构表征。研究结果表明,在聚苯乙烯/纳米金刚石复合微球中,纳米金刚石晶体为立方相,聚苯乙烯为无定形态,颗粒径粒大约为40-70nm,分散较好,比较面积达到230m2/g,该复合材料具有良好热稳定性。进一步的力学系性能测定表明,随着聚苯乙烯/纳米金刚石复合微球添加应用,聚苯乙烯的拉伸强度、断裂伸长率性能得到了明显地改善,但弯曲强度性能有所下降。 The polystyrene/nano-diamond composites micro spheres were prepared in Pickering emulsion by using BPO as the initiator and nano-diamond as emulsifier. The as-prepared products were characterized by X-ray diffraction (XRD), thermo-gravimetric analysis (TGA) and differential thermal analysis (DTA), transmission electron microscopy (TEM), Brunauer-Emment-Teller (BET) measurements, and Fourier transformation-infrared spectrum (FT-IR), respectively. The experimental results showed that the nano-diamond belonged to a cubic crystal phase and the polystyrene was amorphgus in as-obtained product. The product possessed a good dispersity and a uniform size with the diameter in a range of 40nm to 70nm. The specific area approached 230.0m^2/g. In addition, the products had a thermally stable performance. Moreover, the mechanical test have indicated that the performances of polystyrene, such as stretch forming and extension at break have been improved, but bending strength have receded slightly in the presence of such composites.
