REAL-TIME IN-SITU OBSERVATION OF PHOTOINDUCED VAPOR-DEPOSITION POLYMERIZATION OF N-VINYLCARBAZOLE WITH FOURIER-TRANSFORM IR REFLECTION-ABSORPTION SPECTROSCOPY

By using a low pressure mercury lamp as an excitation source, vapor de position polymerization (VDP) of N-vinylcarbazole was carried out. Dep osition and annealing processes were observed with real-time in situ F ourier transform IR reflection absorption spectroscopy. On average, th e him deposited at the substrate temperature of 255-275 K consisted of 65% of an isotropic component and 35% of an oriented component. A pol ymer yield of 95% film was obtained at a substrate temperature of 275 K. The same yield was achieved at an annealing temperature of around 3 50 K when the VDP film deposited at 255 K was annealed in vacuum.
