Polymer dispersed liquid crystal (PDLC) films are a mixed phase of nematic liquid crystals (LC) commonly dispersed as inclusions in a solid polymer[].They have remarkable electro-optical behaviour since they can be switched from an opaque to a transparent state simply by application of an …
WebAug 22, 2002 · We have recently determined the polymer structure of the SAM domain from another protein involved in transcriptional repression, the polycomb group protein polyhomeotic (Ph) [Kim et al., in press]. The Ph-SAM polymer is quite similar to the TEL-SAM polymer even though the proteins have an unrelated domain structure and show … Polymers can crystallize through a variety of different regimes and unlike simple molecules, the polymer crystal lamellae have two very different surfaces. The two most prominent theories in polymer crystallization kinetics are the Avrami equation and Lauritzen-Hoffman Growth Theory. [21] Properties of … See more Crystallization of polymers is a process associated with partial alignment of their molecular chains. These chains fold together and form ordered regions called lamellae, which compose larger spheroidal structures named See more Solidification from the melt Polymers are composed of long molecular chains which form irregular, entangled coils in the melt. Some polymers retain such a disordered structure upon freezing and readily convert into amorphous solids.
