초록

In this paper, we studied the characteristics of surface structure of phenolic resin by water treatment. Phenolic resin which is used as indoor insulators is easily deteriorated by humidity. Water treated sample for 200 hours is subjected to the penetration of water and cracked partially. Water treated sample for 400 hours is found more cracks than that for 200 hours. The initial leakage current of virgin sample is 0.11A, that of water treated sample for 200 hours is 0.07A, and that of water treated sample for 400 hours is 0.05A. FT-IR analysis indicates that absorption peak of carbonyl group appears in virgin sample, but the absorption peak does not appear in water treated sample for 200 hours.
