“…As predicted, the resin 1D synthesized in DMF reveal sharp peak at 1660 cm -1 (1D, Fig. 2) responsible for the -C=N-bonds, created due to the dimethyl formamide [8]. The effect, as described in our previous work [7] will affect final sorption capacity of the resin 1D.…”

In the present studies a series of anion-exchange resins was synthesized in a microwave field. The 1,6-diaminohexane functionalized resins were obtained in presence of selected organic solvents, N,N-dimethyl formamide, dimethyl sulfoxide and 1-methyl-2-pyrrolidone. The resins were employed in batch and dynamic processes of Au(III), Pt(IV) and Pd(II) sorption from tricomponent systems in 0.1 M HCl. The experiment was designed in a way that allowed to determine the use of a specific solvent in the microwave field and how it impacts on properties of the anion exchangers. An influence of a reaction environment was discussed taking into account i.e., dielectric characteristics of the specific solvent, efficiency of the syntheses processes as well as the maximum sorption capacity of the resins. Ultimately the application of a specific reaction environment was set together with sorption of noble metals ability and evaluated using infrared spectroscopy. The proceeded analyzes allowed to determine which organic solvent from the selected ones is the most suitable for microwave-assisted synthesis of the anion-exchange resins.

“…As a result, synthesis was proceeded in N,N-dimethylformamide (DMF) using amines as functionalizing agents. Executed analyzes revealed that the microwaves facilitate creation, instead of amino functional groups, the -C=N-bonds, derived from DMF, resulting with smaller sorption capacity of the received anion exchangers [7,8].…”

“…3) or significantly lower (resins D2-D4MV, Fig. 3) sorption capacity support the conclusion that microwaves could promote the nucleophilic attack of oxygen derived from DMF on the chloromethyl groups located in the polymer matrices [49] creating the -C=N-bonds (Fig. 2).…”

A series of new ion exchange resins was synthesized in a microwave radiation field by modification of chloromethylated styrene/divinylbenzene (S/DVB) and vinylbenzylchloride/divinylbenzene (VBC/DVB) copolymers using amines. The modification processes have been executed simultaneously using the microwave-assisted method and the most efficient, conventional one. The greatest total sorption capacities for noble metals were achieved for two resins conventionally modified using ETDA ion exchange resins based on S/DVB matrices. The microwave-modified resins reveal only slightly lower and in some circumstances even better sorption capacity for noble metals than their conventionally-modified equivalents. The differences are discussed by effect of the synthesis method as evaluated using FTIR spectrophotometry.

“…In contrast, organic solvents (such as N,N, ‐dimethylformamide) are less expected to form emulsions with polymers due to their higher miscibility 56. Indeed, poly(vinylbenzyl chloride) has been reported to dissolve in N , N ,‐dimethylformamide,57 which helps to account for why the pulsed plasma deposited poly(vinylbenzyl chloride) layers are not templated by N,N, ‐dimethylformamide solutions.…”

Functionalised macroporous scaffolds have been fabricated by a decoupled two-step approach comprising plasmachemical deposition of the host material followed by spontaneous emulsion formation using templating molecules. This unique approach allows pore architecture and surface functionalisation to be tailored independently. Other key features encompass conformality to a range of substrate materials or geometries, and the scope for introduction of a wide variety of pore surface functionalities, which for instance include pore size actuation.
