Abstract
Epoxy
resin coated glass slides were used for colloidal particle
lithography, in order to prepare well-defined 2D surface arrays. Upon
the assistance of a large-sized 2D colloidal single crystal as template,
centimeter-sized ordered surface arrays of bowl-like units were obtained.
Systematic studies revealed that the parameters of obtained surface
arrays could be readily controlled by some operational factors, such
as temperature, epoxy resin layer thickness, and template particle
size. With epoxy resin substituting for normal linear polymer, the
height/diameter ratio of bowls in the formed surface arrays can be
largely increased. With further reactive plasma etching, the parameters
of ordered surface arrays could be finely tuned through controlling
etching time. This study provides a facile way to prepare large-sized
2D surface arrays with tunable parameters
