We show that thin films of C60 with a thickness ranging from 10 to 100 nm can promote adhesion between a Au thin film deposited on mica and a solution-deposited layer of the elastomer polymethyldisolaxane (PDMS). This molecular adhesion facilitates the removal of the gold film from the mica support by peeling and provides a new approach to template stripping which avoids the use of conventional adhesive layers. The fullerene adhesion layers may also be used to remove organic monolayers and thin films as well as two-dimensional polymers which are pre-formed on the gold surface and have monolayer thickness. Following the removal from the mica support the monolayers may be isolated and transferred to a dielectric surface by etching of the gold thin film, mechanical transfer and removal of the fullerene layer by annealing/dissolution. The use of this molecular adhesive layer provides a new route to transfer polymeric films from metal substrates to other surfaces as we demonstrate for an assembly of covalently-coupled porphyrins.
我们证明，厚度在 10 到 100nm 之间的 C60 薄膜可以促进沉积在云母上的金薄膜和溶液沉积的弹性体聚甲基二硅氧烷（PDMS）层之间的粘附。这种分子粘附有助于通过剥离将金膜从云母基底上移除，并提供了一种避免使用传统粘附层的模板剥离新方法。富勒烯粘附层也可用于移除预先形成在金表面上且具有单层厚度的有机单层和薄膜以及二维聚合物。从云母基底移除后，单层可以通过金薄膜的蚀刻、机械转移和富勒烯层的退火/溶解来进行隔离并转移到介电表面。这种分子粘附层的使用为从金属基底到其他表面转移聚合物薄膜提供了一种新途径，我们通过共价偶联卟啉的组装证明了这一点。
