A Description of Multiscale Modeling for the Head-Disk Interface Focusing on Bottom-Level Lubricant and Carbon Overcoat Models

<table>Coarse-grained bead-spring models of linear PFPEs (Z-dol, Z-tetraol, and ZTMD) and star-like PFPEs with three and four arms (TA-30 and QA-40), where magenta and red beads represent hydrogenated functional groups.</table>
