AB  - Thermosensitive molecularly imprinted polymers (T-MIPs) on porous carriers were 
      prepared via the synergy of dual functional monomers of 4-vinylpyridine (VP) and 
      N-isopropylacrylamide (NIPAM), for selective recognition and controlled 
      adsorption and release of bisphenol A (BPA) by the temperature regulation. The 
      porous polymer supporter was synthesized by multistep swelling of polystyrene and 
      then both the NIPAM with temperature responsiveness and the basic monomers of VP 
      were grafted on them in a simple way. The resultant T-MIPs showed high binding 
      capacity, fast kinetics, and the adsorption processes were found to follow 
      Langmuir-Freundlich isotherm and pseudo-second-order kinetic models. The 
      adsorption capacity increased slightly along with the rise of temperature (such 
      as 20 degrees C) under lower critical solution temperature (LCST, 33 degrees C) and decreased 
      fast above LCST (such as 50 degrees C). Subsequently, the T-MIPs were employed as novel 
      adsorbents for selective solid-phase extraction (SPE) of BPA from seawater and 
      yogurt samples. Satisfying recoveries in the range of 94.83-98.47% were obtained 
      with the precision of 3.21% at ambient temperature (20 degrees C). Through 6 
      adsorption-desorption cycles, the reusable T-MIPs exhibited a good recoverability 
      with the relative standard error within 9.8%. The smart T-MIPs provided great 
      potentials for selective identification, adsorption/release and removal of BPA by 
      simple stimuli responsive regulation.
