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. The neutron small-angle scattering technique was used to study the structure of the fullerene PVP polymers in aqueous solution and their size and their changes under different contents of fullerenes. The results showed that when the fullerenes were added, Or macromolecular chain, the correlation length of PVP solution is smaller than that of pure PVP solution, and the changes of macromolecular chains are more obvious. Under the condition of different fullerenes, the content of fullerene fullerene PVP molecular chain The size of the group is smaller.
