microstructure, and wettability of newpolyacrylates carrying spaced 4‐perfluorohexylpropyl benzoate and 4‐perfluorooctylpropyl benzoate units in the sidegroups were investigated. X‐ray diffraction analysis proved the formation of different smectic mesophases (SmI2, SmF2, and SmC2) and the evolution of their structures and lattice parameters with temperature. The mesophase polymorphic behavior depended
