Poly liquid crystal composit

Fig. 16. The increase in droplet size can be seen as a function of time for a poly(butadiene) -liquid crystal composite (top). The distribution of the polymer and the liquid crystal can be seen in the first two images (bottom), segregated as before. The surfactant (middle, right) can be seen to be distributed around the droplets and segregated from the matrix. A sample without surfactant... Fig. 16.

Compositions consisting of poly(oligothiophene-thiazole), ( ), having an Af of 40,000 Da were prepared by Hanh et al. (3) and used as organic insulating films in thin-film transistors in liquid-crystal display devices. [Pg.189]

New photoresponsive polymers and peptides have been developed by incorporation of an azobenzene chromophore. The photochemistry of azobenzene-containing polymers has been reviewed,and the ion-conducting polymer composite film of poly(vinyl chloride)/the azobenzene liquid crystal (4)/lithium perchlorate is a promising material for use in photoinduced image storage.Photoisomerization has also been demonstrated... [Pg.331]

For example, SAN is an emulsion or suspension polymerized from styrene plus acrylonitrile, and SAN is graft-polymerized to polybutadiene to form ABS. Antioxidants can be introduced during polymerization as well as during compounding, to protect the double bonds in polybutadiene and acrylonitrile. Block and graft in situ polycondensation polymerization can be used to produce ABS composites and other engineering thermoplastic composites reinforced with poly-p-phenylene terephthal-amide (PPTA) liquid crystal fibers at the molecular level [4]. [Pg.13]

The phase state of lyotropic liquid crystals is mostly determined by a composition of a mixture [27]. Building elements of lyotropics are either rod-like macromolecules (like a tobacco mosaic virus or poly-7-benzyl-glutamate), or micelles formed by amphiphilic molecules in solutions. The shape of a micelle is responsible for the structure of a mesophase [28]. Figure 1.12 shows five possible shapes of building elements (a), responsible for the formation of the corresponding five mesophases (b). [Pg.17]
