제목 Preparation and Properties of Poly(imide-urethane) Copolymers Containing Various DP of Polyurethane Prepolymer for Capacitive Humidity Sensing Materials
초록 To obtain good capacitive humidity sensors in the range of 20~80%RH, the poly(imide-urethane) copolymers were prepared from reactive polyamic acid synthesized from 4.4’-diaminodiphenyl ether (ODA) and pyromellitic diandhydride (PMDA) and polyurethane prepolymer synthesized from poly (tetramethylene oxide) glycol (PTMG) and 4,4’-dicyclohexylmethane diisocyanate (H12MDI). In this study, the degree of polymerization (DP) of polyurethane prepolymer was varied from 3 to 12. However, the DP of reactive polyamic acid was fixed at 30. This study focused on effect of length of polyurethane prepolymer chains on the electric properties for capacitive humidity sensors. This research was supported by the Fundamental R&D Program for Core Technology of Materials funded by the Ministry of Knowledge Economy, Republic of Korea.
