“…Surface modifications of polymer surfaces have been widely performed using plasma, [10][11][12][13][14][15] corona discharge, 16,17 ultraviolet (UV) light, 17,18 ion beams 19 or bombardment, [20][21][22] g-radiation, [23][24][25] and chemical solutions [26][27][28] to modify macroscopic surface properties, such as wettability, friction, adhesion, biocompatibility, molecular recognition and LC alignment. In most cases, the formation of oxygen-containing functional groups, such as -OH and -COOH, occurs on the polymer surfaces.…”
