摘要：

C-60 was supposed to be a super lubricant on the basis of its unique spherical and highly symmetric structures. In the present work, efforts have been made to give some experimental approaches and evidences that strongly support the supposition of the "rolling effect" of C60 For this purpose, three kinds of C-60 LB films were prepared designated for the predictable effects with or without "rolling". By studying the AFM morphologies and their corresponding frictional images, some evidences supporting the "rolling effect" of C-60 were observed in C-60/BA (behenic acid) and C-60/AA (arachidic acid)/OA (octadecylamine), while for the C-60 derivative LB film, results indicated a "nonrolling effect" related to a high frictional force.
