Low profile multidentate lubricants for use at sub-nanometer thicknesses in magnetic media
In one embodiment, a multidentate perfluoropolyether (PFPE) lubricant has the formula Se-So-Si-SL-Si-So-Se, where each So includes at least one perfluoroethyl ether unit, SL is a linker segment, and each Se and Si include at least one functional group configured to attach to a surface. In another em...

| description | In one embodiment, a multidentate perfluoropolyether (PFPE) lubricant has the formula Se-So-Si-SL-Si-So-Se, where each So includes at least one perfluoroethyl ether unit, SL is a linker segment, and each Se and Si include at least one functional group configured to attach to a surface. In another embodiment, a multi dentate PFPE lubricant has the formula Se-So(a)-Si-Sm-Si-So(b)-Se, where each So(a), So(b), and Sm include at least one perfluoroethyl ether unit with the proviso that Sm has a different number of perfluoroethyl ether units than at least one of So(a) and So(b), and each Se and Si include at least one functional group configured to attach to a surface. |
