Control Immobilization of Silver Nanoparticles Track-Etched Membranes / I.N.Fadeikina, E.V.Andreev, O.V.Kristavchuk, O.L.Orelovich, P.Yu.Apel. – Text : electronic // Natural Science Review. – 2026. – Vol. 3, No. 7. – P. 200706. – URL: https://nsr-jinr.ru/index.php/nsr/article/view/110/93. – Bibliogr.: 55.
The study of the interaction of colloidal solution components with microfiltration membranes is ofcontinuing interest, both in the development of composite porous materials and in the numerousapplications of membranes for separating suspensions. This study investigates the transport of sil-ver nanoparticles through track-etched membranes under conditions where the nanoparticles and themembrane surface possess opposite charges. The objective was to establish patterns of nanoparticledeposition based on the membranes structural parameters and the solution flow rate.A simple criterion was derived to determine nanoparticle retention efficiency by considering convec-tion and diffusion within the pores. This criterion was tested through experiments using polyethyleneterephthalate track-etched membranes with pore diameters ranging from 0.1 to 7.1μm, while the av-erage nanoparticle diameter was 24 nm. By varying the pressure drop, the flow rate of the colloidalsolution through the membrane pores was varied.Nanoparticle retention efficiency was determined using optical spectroscopy and energy-dispersiveX-ray analysis. The distribution of nanoparticles on the membrane surface was examined using scan-ning electron microscopy. It was found that the proposed criterion satisfactorily predicts the transitionfrom nearly complete particle retention to complete transmission when key parameters — pore diame-ter, membrane thickness, and pressure drop — are varied.The obtained results provide insights into the controlled immobilization of nanoparticles on mem-brane surface, which is essential for creating functional nanocomposite devices, such as sensors.
