Blend Films with Vertical Stratified Structure

Blend Films with Vertical Stratified Structure [Pg.194]

As discussed in Section 7.2, charge transport in TFTs occurs between the source and drain electrodes, which are usually in the same plane. Therefore, a continuous semiconducting layer at the channel region is needed for TFT operation. Controlling blends to vertically phase separate to form stratified structure presents an effective way to keep the connectivity of semiconducting layer in blended films. In the next section, phase behavior in polymer blend films will be reviewed followed by examples of semiconducting/insuiating polymer blends with vertical stratified structure. [Pg.194]
