説明
The state of dissolved water in polydimethylsiloxane (PDMSi) was studied by FT-IR spectroscopy at 20°C, and the thermal dependence of dissolved water in PDMSi was examined. The state was compared with some low molecular weight siloxane and ether compounds. The effect of water clusters in PDMSi on conduction phenomena was also studied. In PDMSi, the water clusters mainly consisted of small clusters such as a monomer-like dimer (hydrated water molecule with oxygen atom in siloxane polymer). The number of large clusters that formed around ether group in PDMSi was very small in contrast to those in other siloxane and ether compounds. The small water cluster existed stably in PDMSi against heating until 180°C better than any other clusters. Dissolved water did not enhance conductivity until 180ppm. But when the amount of dissolved water exceeded 180ppm, the conductivity remarkably increased. It was found that monomer like dimer mainly contributed to the increase in the conductivity.
