Kyoto,Institute of Technology; Kyoto,University Liquid crystalline elastomers were
prepared by crosslinking side chain type liquid crystalline polymers (precursors),
which had flexible polysiloxane as a main chain, and mesogens with a spacer as
a dangling chain. The content of the ... or by crosslink density. The results
suggested that the interaction between mesogens was the dominant factor for the
orientational order of the mesogens in the liquid crystalline elastomer system
studied.

Introduction Liquid crystalline elastomers (LCEs) are lightly crosslinked polymer
networks with mesogenic groups chemically bonded to polymer chains.1
According to alignment patterns of mesogens, LCEs are distributed into nematic
LCEs, smectic LCEs and cholesteric LCEs. And based on the location of
mesogens, LCEs are categorized into main-chain LCEs and sidechain LCEs.
Similar to low molecular liquid crystals, the rigid mesogens integrated in the
crosslinked networks ...

The simplest LC phase is the nematic (in which the anisotropic liquid-crystal
molecules, termed mesogens, have a preference to be aligned in a specific
direction but have no positional order or regularity; the preferred alignment
direction for the mesogens ... When crosslinks are introduced between the LC
polymer chains (to form a liquid-crystalline elastomer, or LCE), the properties of
these systems become still more interesting.86 The polymer network is now “
topologically” fixed, at a ...

REACTIVE PROCESSING OF THIN FILMS. Faculty: Paula T. ... These polymers
have been of great interest to materials scientists because they couple the
elastomeric mechanical properties of a standard tough elastomer with the ...
crystals. Thus far, all reported syntheses of liquid crystalline elastomers involve
the crosslinking of flexible side chain or main chain liquid crystalline polymers to
form a network.

ABSTRACT Cornerstone Research Group Inc. (CRG) will present a brief
overview on our recent efforts in developing liquid crystal (LC) network polymers
for various applications. These efforts cover different ... Over the past decade,
investigation of crosslinked systems based on rigid rod molecules has increased,
because of the growing understanding that a network built from rigid rod
segments will not behave as a network built from random coil linking groups. This
difference is due to ...
