USE - The method is useful for achieving higher polar anchoring strength of LC using monolayer graphene flakes in an LC device and attaining faster electro-optic switching in an LC device. ADVANTAGE - The method achieves higher polar anchoring strength of LC and attains faster electro-optic switching in LC device. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a liquid crystal device with faster electro-optic switching and higher polar anchoring strength using monolayer graphene flakes made by the method as per se; and (2) a liquid crystal device with faster electro-optic switching and higher polar anchoring strength comprising LC cell having a polyimide (PI) alignment layer, a liquid crystal graphene mixture in the LC cell, where the graphene flakes sediment down from the liquid crystal graphene mixture and preferentially attach to the PI alignment layer during filling the LC cell, the graphene modifies the anchoring property of the LC, the effective polar anchoring energy in the LC cell is enhanced by an order of magnitude via the pi - pi electron stacking between the graphene flakes on the PI alignment layer and LC molecules and the electro-optic response of the LC is accelerated due to the higher anchoring energy in the cell.
