Abstract
We studied dispersants for exfoliating bulk V2Se9 into one dimensional chain units. V2Se9, with a negative zeta potential of -30.1 mV, was acidic and strongly anchored with the amine head of octadecylamine by charge transfer reaction. The steric hindrance by the octadecyl tail promoted the dispersion of V2Se9 to the nano level.
摘要
我们研究了剥离大块 V2Se9 成一维链单元的分散剂。V2Se9 的 zeta 电位为负 30.1 mV，呈酸性，通过电荷转移反应与十八胺的胺基头强烈锚定。十八烷基尾的空间位阻促进了 V2Se9 的分散到纳米级。
