The anchoring energy of blue phase polymer template containing different concentration of conventional polymer has been studied. The lower bound of polymer concentration to form the chiral three-dimensional template of blue phase is confirmed. And it was demonstrated that the template anchoring energy has a threshold value to reassemble the double twist cylinder structure of blue phase liquid crystal by either refilling same-handed chiral materials or reverse-handed chiral materials which may help to improve the driving capacity of the polymer stabilized blue phase liquid crystal.
