The paper provides some new insight of the molecular conformation of the PFPE with functional end groups on hard disk surfaces by considering the dip coating process. It is proposed that the change in the molecular conformation during the dip coating process can be divided into three stages: adsorbing stage, developing stage and drying stage. A formula of predicting the monolayer thickness of the PFPE lubricant on hard disk surfaces is also proposed.
