Phase equilibria and phase separation dynamics in a polymer composite containing a main-chain liquid crystalline polymer

Phase separation dynamics of a polymer dispersed liquid crystal

Phase separation in a polymer dispersed liquid crystal (PDLC), consisting of a main chain liquid crystal (E7) and polymethyl methacryhte (PMMA), was studied by means of light scattering and optical microscopy. The PMMAm mixture exhibits an upper critical solution temperature (UCST), overlapping with a nematic-isotropic transition of the E7 liquid crystal. Several temperature quenches were under...

A flow - induced phase inversion in immiscible polymer blends containing a liquid - crystalline polymer studied by in situ optical microscopy

The phase inversion from a morphology of hydroxypropylcellulose in water ~HPC50%! droplets in polydimethylsiloxane ~PDMS! matrix to a morphology of PDMS droplets in HPC50% matrix can be induced by a change of shear rate, due to a viscosity ratio inversion. Such a process passing through four different transient morphological stages was studied by optical microscopy in a transparent shear device...

dielectric elastomer actuators, [ 17 ] and memristors. [ 18 ] Liquidphase gallium–indium alloys are popular for this “microfl uidics” approach to stretchable electronics since they are nontoxic and form an oxide layer [ 19–22 ] that aids in microcontact printing, [ 23 ] electrode alignment, [ 24 ] and 3D printing. [ 25 ] Finally, a common approach to stretchable electronics is to embed thin fi ...
