| 抄録: | We have performed sum frequency generation (SFG) spectroscopy of water molecules on a polycarbonate (PC) film with and without 1 minute O_2 plasma exposure. The intensity of SFG signal corresponding to the O-H stretch vibrations of water at a water/PC film interface was ～1000 times as low as that of signal from a water/quartz interface. In the SFG spectrum of water facing a pristine PC film, peaks at 3270 and 3440 cm^<-1>, and a shoulder at 3620 cm^<-1> were observed. In the SFG spectrum of water on the film exposed to O_2 plasma, peaks were observed at 3200 and 3450 cm^<-1>. The peak at 3270 cm^<-1> red-shifted to 3200 cm^<-1> by the O_2 plasma exposure. The intensity of the peak at 3200 cm^<-1> was higher than that at 3450 cm^<-1>. The shoulder at 3620 cm^<-1> disappeared after the O_2 plasma exposure. The modulations of these peaks represent that the packing structure of water molecules was more ordered on the film after the O_2 plasma exposure. |
