Fig. 1: Fabrication of gear-shaped microparticles (MPs) by “one-pot microfluidic fabrication” (OPMF) system.
From: One-pot microfluidic fabrication of micro ceramic particles
a Schematic illustrations for the OPMF system and synthesizing mechanism. An anqueous bulk solution (BS), composed of nanoparticles (NPs), acrylamide (AM), and N, N’-methylenebisacrylamide (MBAM), is injected into microfluidic device along with the curing solution (CS) which is composed of N, N, N’, N’-tetramethyl ethylenediamine (TEMED) and ammonium persulfate (APS). After online mixing and in-situ polymerization, a compound made out of polyacrylamide (PAM) and NPs is fabricated. b “Groove & tongue” assembling for gear-shaped microfluidic channel (MC) fabrication inspired by the ancient Chinese “mortise & tenon joint” timber structure. c UV-vis spectra and images of BSs and CS. d Viscosity characterization of three BSs determined by shear rate. e Modulus transformation imitation of the precursor inside MCs during synthesizing. f Optical images of the obtained gear-shaped MPs. g Distribution curves and statistical analysis for outside diameter (Do), root diameter (Dr) and cross-section area (ag) of the obtained gear-shaped MPs with the population number 50.
