Thermo-reversible gelation of liquid crystals using di-benzylidene-D-sorbitol
Mechanically stable thermo‐reversible gels of the liquid‐crystal LC‐E7 with 1,3:2,4‐Di‐O‐benzylidene‐D‐sorbitol (DBS) form white light‐scattering films that are reversibly switchable to a clear state by AC electric fields. It is established that the light‐scattering nature of DBS/LC‐E7 gels is an in...

Summary: | Mechanically stable thermo‐reversible gels of the liquid‐crystal LC‐E7 with 1,3:2,4‐Di‐O‐benzylidene‐D‐sorbitol (DBS) form white light‐scattering films that are reversibly switchable to a clear state by AC electric fields. It is established that the light‐scattering nature of DBS/LC‐E7 gels is an intrinsic material property that originates from the occurence of a monotectic‐type point (“mesotectic”) at very low DBS‐concentration in the phase diagram of the DBS/LC‐E7 system. |
