中文摘要：

研究了阳离子表面活性剂CTAB,阴离子表面活性剂SDS和非离子表面活性剂TX-100和TX-405对水介质中C60纳米晶体颗粒的光化学反应活性诱导效应.结果表明,在阳离子表面活性剂CTAB、阴离子表面活性剂SDS和非离子表面活性剂TX-405中,C60纳米晶体颗粒没有显示明显的光化学反应活性,而非离子表面活性剂TX-100能够明显诱导C60的光化学反应活性.紫外-可见吸收光谱、DLS分析和TEM成像都表明,在TX-100溶液中,C60从聚集状态向分子状态转变,尺寸变小,因而恢复其分子态C60的光化学反应活性.

英文摘要：

Work presented here evaluated the effect of dispersion of C60 nano-particles on its photochemical reactivity in different types of surfactants including anion,cation and non-ion surfactants.The results indicate that C60 did not show any significant photochemical reactivity in the cation surfactant CTAB,anion surfactant SDS,and non-ionic surfactant TX-405 solution,while non-ionic surfactant TX-100 induced C60 nano-particle dispersion,and restored its molecular photochemical reactivity.Analyses by UV-vis,DLS,and TEM suggest that C60 transformed from aggregated form to molecule form in TX-100,with a decreased hydrodynamic diameter.
