BLENDS IN 2 DIMENSIONS - MIXTURES OF A FERROELECTRIC LIQUID-CRYSTALLINE COPOLYMER WITH ITS SIDE-CHAIN MONOMER AT THE AIR-WATER-INTERFACE

In an attempt to adjust the lateral density of monolayer and multilaye r films of a ferroelectric liquid crystalline copolymer, blends of the copolymer were made with the corresponding mesogenic monomer unit. Th e monomer was chosen as the second component since it forms monolayer films which are more condensed than the copolymer and because of its m iscibility with the structurally similar copolymer. Analysis of the in teraction between the molecules of the mixed monolayers included II-ar ea isothermal data, calculation of the excess Delta G(mix), thermal de pendence of isotherms, and Brewster angle microscopy. On the basis of these results, the films appear to be completely miscible over all con ditions presented and the blend monolayer films are more condensed tha n the pure copolymer films.
