Abstract:
Tri(propylene glycol) diacrylate (TPGDA) was found to be an excellent monomer for the stabilization and dispersion of inorganic nanoparticles. Uniform nano-Au/poly(TPGDA) and nano-ZnO/poly(TPGDA) composite microbeads were synthesized in situ using a designed axisymmetric capillary-based flow-focusing microfluidic device without any additional surfactant or coupling agent. Using the designed mixing-enhanced microfluidic device, homogeneous nano-inorganic/polymer composites with a high content of nanoparticles were obtained. Morphologies of the composites were characterized by SEM, TEM, surface microscopy, dark-field microscopy and internal fluorescence.
