摘要
应用中子小角散射技术研究了水溶液中富勒烯PVP聚合物的链团结构及其大小以及它们在不同富勒烯含量下的变化.结果表明当加入富勒烯后,不论是PVP单体分子链还是大分子链团,其相关长度与纯PVP溶液相比均变小,且大分子链团的变化更为明显;在不同富勒烯含量情况下,高富勒烯含量的富勒烯PVP分子链团的体积更小.
Small-angle neutron scattering technique is employed to investigate the structure of fullerene-PVP polymers and the variation of their size with fullerene content. The results indicate that the relative lengths of both mono-molecule and macromolecule chains in solution with fullerene are shorter than those in pure PVP solution, and the volumes of fullerene-PVP polymers in solution with high fullerene content become much smaller.
