Temperature-responsive poly (N-isopropylacrylamide) (NIPAMn) was grafted onto porous silica (Sil-NIPAMn) to be used as stationary phase for normal-phase high performance liquid chromatography (NP-HPLC). Specific interaction ability and unique selectivity were detected between NIPAMn and polyaromatic hydrocarbons (PAHs) through monitoring the retention time with increasing the temperature in NP-HPLC process. The results showed that Sil-NIPAMn has better retention behaviors for structural isomers of PAHs when the temperature is above its lower critical solution temperature (LCST) in mixture of n-hexane/isopropanol. It indicates that NIPAMn grafted on the silica shows phase transition from random coil to stretch state to increase interaction between solutes and stationary phase when temperature is above its LCST.
