  To guide the preparation of advanced materials with chemical engineering theories and methods is one of the important academic thoughts of NJUT’s State Key Laboratory of Materials-Oriented Chemical Engineering. Supported by National Natural Science Foundation of China (Grant, 10976012, Grants, 21076103 and Grants, 21006046), the Priority Academic Program Development of Jiangsu Higher Education Institutions (PAPD) and State Key Laboratory of Materials-Oriented Chemical Engineering Foundation, Professor Chen Su from State Key Laboratory of Materials-Oriented Chemical Engineering and College of Chemistry and Chemical Engineering of NJUT, together with PhD. Yu Zi-yi, fabricates CPC supraparticles with controllable shape and function for the first time in the world with new chemical engineering method of controlling micro-pump and adjusting microfluidic chip, i.e., Microfluidic technology. The research results has been published on Angewandte Chemie International Edition (Impact Factor 12. 730, 2010), (“Triphase Microfluidic-directed Self-assembly: Anisotropic Colloidal Photonic Crystal Supraparticles and Multicolor Patterns Made Easy”, Angew. Chem. Int. Ed., 2012, DOI: 10. 1002/anie. 201107126), and has been listed as Hot Article.

  Microfluidic technology and related theoretical studies is one of the highlights of the international science and technology research frontier. Reduced microfluidics and relevant chemical reaction to the micron and nanometer scale can produce unique scientific theories, technical advantages and promising applications. The self-assembly of the monodispere colloidal particles were prepared in micro-droplet templates by adjusting the interfacial tension of a triphase microfludici for the first time, which can control the shape of CPC supraparticles and created CPC with superparamagnetism through the encapsulation of magnetic nanoparticles. Besides, taking CPC as color development unit for the adjustable features of CPC band gap, the researcher successfully constructed Gyricon Display with wide viewing angles, which is expected to be applied in electronic paper, and outdoor display, etc. This successful study not only enhances the knowledge of microfluidic interface assembly but also expands and enriches preparation of advanced CPC materials, which is highly rated by reviewers. Together with a serial of papers published in the first-class international journals (J. Am. Chem. Soc 2011, 133 (22), 8412-8415, Angew. Chem. The Int Ed 2011, 50 (16), 3706-3709, Adv. Mat 2011 23 (26), 2915-2919), the study represents a new level of State Key Laboratory of Materials-Oriented Chemical Engineering in interface assembly and microfluidics.
