Dewetting process of polymer films is a hot research and application field in surface and interface science.Hole-growing dynamics is an important part of the dewetting dynamics

further research on it not only can contribute to our understanding of the dewetting process

but also provide theoretical guidance for the design of polymer patterned surfaces and interfaces.The richness of the properties about the hole-growing dynamics has been the subject of extensive theoretical

experimental and simulation studies and lots of great progresses have been made in recent years.In this paper

our central work is focused on three main problems

including reviewing these most important works

elucidating the difference between theoretical predictions and experimental or simulation results

and proposing the corresponding problems.
