For wider temperature blue-phase liquid crystal (BPLC), the optimized structures of blue-phase liquid crystal with 4 '-(6-amino-hexyloxy)-biphenyl carbonitrile modified graphene oxide (GOre-LC) platelets were discussed in this article. It was shown experimentally that the blue-phase stability was enlarged based on the doping GOre-LC, a stable blue-phase with a wide temperature range (4.9 degrees C) was obtained, and a peculiar optical texture of the BP I phase was observed.
