Polyimide/Clay nanocomposites for the flexible colorless substrate |
초록 |
Flexible colorless substrate for organic electroluminescent device have been prepared 2,2’-bis-(3,4-dicarboxyphenyl)hexafluoropropane dianhydride(6FDA) and 2,2’-bis(trifluoromethyl)-4,4’-diaminophenyl(TFDB)/clay nanocomposite films. Polyimide(PI) is used largely for microelectronics. However it would be desirable to reduce the coefficient of themal expansion(CTE), amount of moisture absorption and gas premeability, since those properties of PI are not sufficient for advanced electronics use. As montmorillonite(MMT) consists of stacked silicate sheet about 2000Å in length, 10Å in thickness. it has a low CTE and a high gas and water barrier property (MMT is dispersed homogeneously into PI matrix and oriented parallel to the film surface). Thanks to this special structure of clay, the defects of PI are improved. As clay contents are increasing, PI/clay nanocomposites show better properties than pristine PI. However the transparency of the PI/clay nanocomposite fims are reduced a little. |
