| Outline of Final Research Achievements |
We synthesized various block copolymers consisting of PNIPAM to form thermo-responsive nanocylinder channels and PMA(LC) acts as a film-matrix and as a director of PNIPAM cylinder domains through the thermotropic liquid-crystal orientation, and explored suitable film-preparation conditions for the film to form a perpendicularly oriented cylinder microphase separation structure.
In diblock copolymer film, PNIPAM-b-PMA(LC), a targeted structure was obtained by addition of a little amount of water to the polymer solution in film-preparation. In triblock terpolymer, poly(ethylene oxide)-b-PNIPAM-b-PMA(LC), it would be suggested that a targeted structure was obtained by just thermal annealing.
To obtain a self-standing film, we introduced thermal- or photo-crosslinkable part in PMA(LC) and investigated their crosslinking ability. As a result, a self-standing film successfully obtained through photo-crosslink reaction.
