i want to study growth of liquid crystal.
suggest the compound.
also tell how to study different characteristics of LC. |

My impression was that they 'grow' in the sense that under certain
conditions - e.g. slow cooling from a frothy boiling mass - the
characteristic length at which you find correlations steadily
increases. |

I tried growing solidified liquid crystals for awhile. The goal was to
make the largest uniform solid crystal sheet.
It was surprising, a slow cooling was very bad. All sorts of distinct
little crystals grew. A moderate five second cooling had some larger
surfaces appear. I was able to grow about 1mm square uniform
crystals.
The technique necessary was the seed crystal. I never got that far
because I only need 1mm square surfaces to test. |
