“…[16][17][18][19] Many researchers have also investigated the removal of aluminum ions from the solution by imprinting polymers. [20][21][22][23] For instance, Wentao Li synthesized an imprinted polymer named Al(III)-IIP using aminopropyl triethoxysilane and acrylic acid-graed silica. Al(III)-IIP exhibited a signicant adsorption capacity for aluminum ions, reaching 106 mg g −1 ; selectivity coefficients for Al(III) in mixtures with Nd(III) is 17.76.…”

“…Thus, the molecular recognition is based on imprinting effect that is resulted from precomplexation of template and monomers by arranging the functional groups around the template throughout the polymeric network. Hence, stable binding sites with high selectivity in terms of shape and size, and even in terms of temperature and pH memory complementary to the template are formed 3,4 (Figure 1). Metal ion imprinted polymers (IIPs) can be prepared via molecular imprinting technique in the presence of metal ions and have highly specific binding sites for selective removal of metal ions from aqueous solutions in water and wastewater treatment as an application field 5 .…”

Smart polymers with fast response to slight changes show high practicability in separation and removal applications, such as water and wastewater treatment. Molecular imprinted polymers (MIPs) are designed to possess specific binding sites enabling the recognition of the target analytes. In this article, the newly synthesized smart adsorbents were used for the selective removal of nickel [Ni(II)] ions from aqueous solutions, which have dual (pH and temperature) memory for the recognition of Ni(II) ions due to the self-assembled recognition sites in MIP structure. The Ni(II)-MIP smart cryogels were prepared by cryopolymerization of N-isopropylacrylamide (NIPAm) and N-methacryloyl-Lhistidine (MAH) monomers to incorporate their smart features for removal of Ni(II) ions in a selective and temperature-modulated way. The maximum binding capacity of Ni(II) ions onto MIP smart cryogel was determined at pH 6 as 414 μg g −1 at 20 C and only 104.5 μg g −1 at 40 C, respectively. The adsorption reached an equilibrium within 30 min, while 85% of the bound amount of Ni(II) ions was achieved in only 15 min. This unique MIP cryogel as a smart and selective adsorbent was able to remove Ni(II) ions immediately by a significant temperature and pH change as an alternative application for water and wastewater treatment.

To enhance the mechanical and water barrier properties of soy protein isolate (SPI/)/polyvinyl alcohol (PVA) blends, montmorillonite (MMT), as a layered silicate clay was incorporated and SPI/PVA/MMT composite films were successfully prepared by melt processing in this work. The results showed that the structure of the composites was highly dependent on the MMT content. MMT nanofillers could act as the heterogeneous nucleating agent for PVA, which accelerated the crystallization and increased the size distribution of the crystalline. With the increase of MMT content, the tensile strength and Young's modulus of the composites increased, exhibiting the fine reinforcing effect. Due to the effective restriction of the highly disordered MMT lamellae on the matrix segment, the water sensitivity of the composites decreased and at the same time, the thermal stability improved. The resulting nanocomposite films exhibited wide applications as biodegradable materials, green packaging films, etc. POLYM. COMPOS., 40:3768-3776, 2019. POLYMER COMPOSITES-2019 FIG. 8.
