“…This indicated that the OH 2 in the solution interacted with the À ÀOH in the BPA molecule, which prevent the interaction between BPA and PES recognition sites. 5,17 Interestingly, as shown in Figure 3(b), the binding and recognition behavior recovered as soon as possible, when 0.50M HCl solution was added into the BPA alkali solution, and the pH value of the solution changed to 1.1. The amounts of BPA binding to the imprinted PES particles were higher than that to the nonimprinted ones.…”

“…The diameter and the specific surface areas of the particles depended on the diameter of the syringe needle and the polymer solution. 17 In this study, the particles were 2.3 6 0.1 mm in diameter for both the imprinted and nonimprinted particles. The specific surface areas, which were determined using the mercury porosimetry, were 119.5 and 122.3 m 2 g 21 , respectively, for the nonimprinted and imprinted particles.…”

“…Clearly, the specific surface area, which was a significant factor related to the binding, was similar for the imprinted and the nonimprinted particles. 17 Extraction of BPA from the particles was carried out by immersing the imprinted particles into ethanol, acetone, and acetone/ethanol (V : V 5 25 : 75), respectively. As shown in Figure 1(a,b), SEM was used to characterize the cross sections of the imprinted particles extracted in ethanol.…”

Bisphenol A (BPA) imprinted polyethersulfone (PES) particles were prepared for the recognition of BPA by means of phase inversion method. During the preparation of the BPA-imprinted particles, acetone, ethanol and acetone/ethanol solutions were used to extract the template BPA molecules. The SEM morphology and the recognition experiments suggested that the acetone/ethanol provided an efficient way to extract the BPA from the imprinted PES particles. The binding and recognition ability for the imprinted particles disappeared under alkali condition, and they recovered as soon as possible when the solution changed from alkali condition to neutral or acid condition. With the addition of Na 1 , Mg 21 , and Cl 2 , the binding amounts for the imprinted particles and nonimprinted particles were not changed heavily, which suggested the potential application of the particles in seawater. In the BPA/BPA analogue mixed solution, the imprinted particles showed selectivity for the template molecules BPA. The FTIR results suggested that the PES and BPA interacted through hydrogen bonds.

Abstract:Molecularly imprinted polymers (MIP) exhibiting high selectivity and affinity to the predetermined molecule (template) are now seeing a fast growing research. However, optimization of the imprinted products is difficult due to the fact that there are many variables to consider, some or all of which can potentially impact upon the chemical, morphological and molecular recognition properties of the imprinted materials. This review present a summary of the principal synthetic considerations pertaining to good practice in the polymerization aspects of molecular imprinting, and is primarily aimed at researcher familiar with molecular imprinting methods but with little or no prior experience in polymer synthesis. The synthesis, characteristic, effect of molecular recognition and different preparation methods of MIP in recent few years are discussed in this review, unsolved problems and possible developments of MIP were also been briefly discussed.

A nickel vanadyl molecularly imprinted nanofiber (NVMIN) was developed by the electrospinning technique, employing polyethylene terephthalate (PET) and linear polyethylenimine (L-PEI) as the matrix polymers, nickel tetraphenylporphyrin (NTPP) and vanadyl tetraphenylporphyrin (VTPP) as the mixed-template molecules. The fabricated NVMIN was evaluated as a sorbent for the removal of NTPP and VTPP from organic media. The effects of trifluoroacetic acid (TFA), dichloromethane (DCM), dimethyl sulphoxide (DMSO), pentane (PEN) on electro-spinnability of the PET/L-PEI solutions and the morphological appearance of the PET/L-PEI fibers were investigated qualitatively by means of a scanning electron microscope (SEM). Electrospinning of 14 to 30% w/v PET/L-PEI solutions in TFA produced beaded and smooth fibers, depending on the concentration range. The addition of DCM and PEN as modifiers helped improve the electrospinnability, with PEN being the best, while the addition of DMSO made the solutions not spinnable. The results indicated that the NVMIN showed higher affinity (99% higher) for NTPP than the non-imprinted nanofiber (NIN) indicating that the NVMIN contained a lot of specific binding sites. It was determined that the NVMIN exhibited the same selectivity specialism for both NTPP and VTPP. However, the interaction strength was strongly dependant on the type of solvent, where the strongest interaction was achieved in chloroform. In addition, the thermodynamic parameters calculated from the adsorption data suggested that the adsorption of NTPP onto NVMIN was a spontaneous and exothermic process.
