Microfluidic-assisted synthesis of uniform polymer-stabilized silver colloids

We report the controlled synthesis of polymer-stabilized silver nanoparticles (AgNPs) by using microfluidic devices. The microfluidic-based method enabled preparation sub-50 nm AgNPs which are much more homogenous compared to those produced in batch reactors where control over flow and mixing conditions was not performed. concentration precursor (silver nitrate - AgNO3) can be tuned reach smaller or larger nanoparticles, although within a fairly narrow range. Regardless polymeric shell, reducing agent influences size polydispersity manufactured colloids, relatively lower amounts allow for manufacturing homogeneous nanoparticles. Notably, use block copolymer PEO-b-P2VP as stabilizing leads (23–51 nm) stabilized PVP (7–14 possibly linked different arrangements polymer chains at interface between solutions. highly uniform, with distribution width influenced (FWHM < 100 were determined higher concentrations), this variable does have distinguished effect on final colloids. Overall, we provide relevant new knowledge framework since variety other probed, outcomes regarding particle size. reported findings thus guide significant advances towards polymer-coated metallic particularly when target is required.
