Claim 0:
1. A lubricant comprising:
a plurality of segments, each linked together by ether linkages according to a general formula:

Re1-Rb1-Ri-Rc-Ri-Rb2-Re2;

wherein Rc is a divalent center segment including a perfluoroalkyl ether moiety;
wherein each of Rb1 and Rb2 is, independently, a sidechain segment including a perfluoroalkyl ether moiety;
wherein each Ri is, independently, a divalent linking segment including a functional group including elements from Group 13-17 of the periodic table of the elements;
wherein each of Re1 and Re2 is, independently, a monovalent end segment including a functional group including elements from Group 13-17 of the periodic table of the elements; wherein Rb1≠Rc≠Rb2; and
wherein the lubricant has a bonding percentage of about 70% to about 100% corresponding to a total area of a surface on which the lubricant is located.
