Abstract
We have developed a highly stable, layered structure for ternary copolymers in Langmuir-Blodgett (LB) films, with substantial durability over the long term. In these ternary copolymer LB films, amorphous side-chains support the layered structure, and the distance between the layers is controlled at the nanometer scale by the composition of hydrogenated and fluorinated side-chains. In the present study, we investigated the molecular orientation of organized molecular films with regard to solid-state structure of newly synthesized ternary comb copolymers with a carbazole ring by surface pressure-area isotherms, in-plane and out-of plane X-ray diffraction, and atomic force microscopy. Structural features of LB film of ternary copolymers may result from enhancement of π-π interactions between the arranged carbazole rings. The side-chains of the copolymers in the two-dimensional films are apparently in a miscible state, and monolayers form a homogeneous amorphous surface because of cancellation of differences in van der Waals forces between the two types of side-chains. As a result, new polymer nanomaterial expected to form a highly ordered layer structure having substantial durability over the long term is proposed because amorphous side-chains support the layer structure in the LB multilayers.
