Facile Access to High Solid Content Monodispersed Microspheres via Dual-Component Surfactants Regulation toward High-Performance Colloidal Photonic Crystals.

Monodispersed microspheres play a major role in optical science and engineering, providing ideal building blocks for structural color materials. However, the method toward high solid content (HSC) monodispersed microspheres has remained a key hurdle. Herein, a facile access to harvest monodispersed microspheres based on the emulsion polymerization mechanism is demonstrated, where anionic and nonionic surfactants are employed to achieve the electrostatic and steric dual-stabilization balance in a synergistic manner.

One-Pot Synthesis of Robust Fluorescent Nanocomposite Gel via Frontal Polymerization.

Fluorescent nanocomposite gels have attracted increasing attention due to their excellent optical properties, as well as enhanced mechanical strength originating from the nanoparticles. At present, two-step methods are usually employed, where fluorescent nanoparticles are firstly prepared, followed by mixing with gel precursor to achieve the final products after gelation, which suffer from the disadvantages of a tedious and time-consuming process. Thus, the development of a facile strategy is highly desirable, which still remains an obstacle.
