Essentially, click here in all publications selleck compound dedicated to the synthesis and application of Ag-MNPs in various supporting polymers, the main attention was paid to the properties of MNPs, i.e., to the properties of just one component of PMNCs, which are determined by PMNC components: the polymer matrix, the NPs, as well as the interaction between them. In this communication, we report the results obtained by studying the properties of the polymer component of FMNPs composed of Ag-MNPs and Purolite C100E resin of the gel type. It has been shown that IMS of Ag-MNPs in

a gel-type polymer results in the dramatic changes of its morphology. Methods Reagents and materials All chemicals, such as AgNO3, NaOH (Panreac, S.A., Barcelona, Spain), NaBH4 (Aldrich, Munich, Germany), mineral acids, and others, were of p.a. grade and were used as received. Bidistilled water was used in all experiments. The ion exchange capacity of C100E resin (Purolite, Bala Cynwyd, PA, USA) was determined by acid-base titration to equal to 2.1 meq g−1. Synthesis and characterization of PMNCs The

IMS of Ag-NPs in Purolite C100E resin was carried by following the standard procedure https://www.selleckchem.com/products/azd6738.html which included the loading of the functional groups of the polymer in the initial Na form with Ag+ ions by using 0.1 M AgNO3 solution followed by their reduction with NaBH4 solution. A sample Adenosine triphosphate of approximately 10 mg of PMNC was immersed in aqua regia (1 mL) to completely dissolve Ag-MNPs. The final solution was filtered through a 0.22 μm Millipore filter (Millipore Co., Billerica, MA, USA) and diluted for quantification of metal content by using induced coupled plasma optical emission spectrometry (Iris Intrepid II XSP spectrometer, Thermo Electron Co., Waltham, MA, USA) and ICP-MS (Agilent 7500, Agilent Technologies, Inc., Santa Clara, CA, USA). The average uncertainty of metal ion determination was less than 2% in all cases. The specific surface area and the porosity measurements were carried out by using BET technique on Micromeritics ASAP-2000

equipment (Micromeritics Instrument Co., Norcross, GA, USA). Scanning electron microscope (SEM) coupled with an energy-dispersive spectrometer (EDS) (Zeiss EVO MA 10 and Zeiss MERLIN FE-SEM, Carl Zeiss AG, Oberkochen, Germany) and transmission electron microscope (TEM) studies were carried out using JEOL 2011 and JEOL 1400 (JEOL Ltd., Akishima, Tokyo, Japan). SEM and TEM techniques were used to obtain the metal concentration profiles across the cross section of the FMNP-containing materials, to characterize the morphology of the polymer surface, and for determination of MNP diameters. The PMNC samples were prepared by embedding several granules in the epoxy resin followed by cutting with an ultramicrotome (Leica EM UC6, Leica Microsystems Ltd.
