<p>A polymer for use in an alignment layer for a liquid crystal material is provided. The polymer comprises a polymer backbone comprising a plurality of repeating units, said repeating units being divided into at least two groups, wherein each repeating unit in a first group of said repeating units is functionalized with a pendant sidechain of a first type S 1 ; each repeating unit in a second group of said repeating units is functionalized with a pendant sidechain of a second type S 2 ; said first type of sidechain S 1 comprising a fluorine substituted hydrocarbon group; and said second type of sidechain S 2 comprising a siloxane. The polymer of the invention promotes homeotropic alignment of liquid crystal materials.</p> |
