Poly( N ‐isopropylacrylamide) is a temperature‐responsive polymer, which is hydrophilic at low temperature but hydrophobic at high temperature. Using this characteristic, the polymer was bonded to the inner surface of fused‐silica capillary to prepare a temperature‐responsive column to study the separation behavior in electrochromatography.
