Hey all can some one tell me what substance can I use as Polarized Liquid Crystals, like the once used in black and white LCD displays... I want the cristals to become dark (polorize in certain way) when I add elctricity to them.
Any Ideas? I was looking for a comercially avalible substance but no luck.. hope some one can guide me in the right direction (even though its not 100% chem question)
Thanks for *delete me*
