The reconstruction capability of the blue phase (BP) template with low polymer concentration was investigated. A threshold polymer concentration to reconstruct the BP with the chiral three‐dimensional template was confirmed in different kinds of polymer systems. The anchoring energy of the template may reassemble the double twist cylinder structure of BP liquid crystal (BPLC) by refilling either the same‐handed or reverse‐handed chiral materials within a certain range of helical twisting power (HTP). Meanwhile, because of the lowered anchoring energy, the kerr constant of the reconstructed BPLC increased by 104%, from 1.81 nm/V 2 to 3.70 nm/V 2 , by refilling the reverse‐handed chiral material.
