| 제목 | Synthesis and Properties of the Clay / Polyuethane Nanocomposite by the Clay and Polyol Modification |
| 초록 | Clay / polyurethane nanocomposites were synthesized with the clay, which was modified with polymeric 4,4' diphenylmethane diisocyanate (PMDI). In the miwing speed 3000 rpm, silanol group of the clay and NCO group of the PMDI were reacted in the excess DMF ( dimethyl formamide ) for 24 hours. After reaction, excess DMF was separated from the modified clay with suction and evaporation. FT-IR analysis of the modified clays demonstrated that NCO characteristic peak was observed in the FT-IR analysis of the modified clay. The clay / polyurethane nanocomposites were obtained from the reaction between the polyol and PMDI modified with clay. also, properties of the clay / polyurethane nanocomposites which are prepared by the PMDI and polyol modified with clay will be presented. Ackonwledgement; This research was surpoported by a grant(code BC1-102) from Carbon Dioxide Reduction & Sequestration Research Center, one of the 21st Century Frontier Programs funded by the Ministry of Science and Technology of Korea government. |
