利用原位乳液聚合的方法合成得到了聚苯胺(PANI)/纳米金刚石复合微球。用X射线衍射(XRD)、热重-差热(Tg-DTA)、透射电子显微镜(TEM)、粒径分析(PSD)、比表面积分析(BET)、红外光谱(FT-IR)及紫外-可见光谱(UV-Vis)等技术分别对获得的PANI/纳米金刚石复合微球进行了结构、形貌、表面表征。结果表明,在PANI/纳米金刚石复合微球中,纳米金刚石为立方相,复合微球介于10～30nm,粒径分布窄,分散性良好,比表面积可达270m2/g,且具有较好的热稳定性。结构分析证实在PANI/纳米金刚石复合物中,PANI与纳米金刚石之间存在氢键键合机制。
Polyaniline (PANI) / nano-diamond composite microspheres were synthesized by in-situ emulsion polymerization. XRD, FT-DTA, TEM, PSD, BET, FT-IR and UV- Vis spectroscopy (UV-Vis) and other techniques were respectively PANI / nano-diamond composite microspheres were characterized by structure, morphology, surface. The results show that nano-diamond is a cubic phase in the PANI / nano-diamond composite microspheres. The composite microspheres are in the range of 10-30nm with narrow particle size distribution and good dispersibility. The specific surface area of the nano-diamond is 270m2 / g, Thermal stability. Structural analysis confirmed that in PANI / nanodiamond composites, there is hydrogen bonding between PANI and nanodiamonds.
