Patent ID: 8535805

Claim:
A polymer comprising: wherein R 1 is an organic group; wherein each 2 is H or a chemisorbed group; wherein the polymer comprises at least one chemisorbed group; wherein n is a positive integer; and wherein the polymer is made by: converting a di-p-xylylene paracyclophane dimer to a reactive vapor of monomers, the reactive vapor having a flux; depositing the reactive vapor under vacuum onto a substrate held fixed in a specific angle of orientation relative to the vapor flux to form nanostructured poly(p-xylylene) film; reacting the nanostructured poly(p-xylylene) film with an agent to form hydrogen atoms attached to the poly(p-xylylene) film that are reactive with a precursor of the chemisorbed group, if the deposited film does not contain the hydrogen atoms; and reacting the hydrogen atoms with the precursor of the chemisorbed group.
