Introduction

My research area is mainly focused on high gravity process intensification, the preparation and applications of nanodispersions. Facing the demands of national strategic industries of energy saving and environmental protection, green and low-carbon, life and health, low-cost, large-scale and controllable preparation of high-performance nanodispersions and applied science were focused. The novel investigation was systematically performed from fundamental, novel technology to engineering application. The main academic innovations include two aspects. (1) A novel method of high gravity reactive crystallization-modification extraction separation (“high-gravity+” method) for the preparation of transparent nanodispersions are proposed by utilizing the mechanism of molecular chemical engineering, combing surface design, modification and dispersion technology, which is never reported. (2) By studying the control mechanism, structure-property relationship and scale-up preparation fundamentals of transparent nanodispersions, this will provide the experience and theoretical guidance for the large-scale preparation and engineering application of the high-performance materials.

Research

The monodispersion and low-cost scale-up controllable preparation of nanoparticles is one of important international scientific and technological challenges. In view of this, based on the preparation of inorganic nanoparticles by the high gravity reactive crystallization method pioneered in the world by our team, a new idea of combining surface modification and extraction separation is introduced to overcome the dispersion problem of nanoparticles that cannot be solved by the original high gravity method. A novel method of high gravity reactive crystallization combining extraction separation (“high gravity +” method) are thus innovatively proposed for the preparation of transparent nanodispersions of monodispersed nanoparticles. With this method, the scientific problems of controllable preparation of nanoparticle size, morphology, crystal shape and monodispersion were solved, and the polarity matching regulation of dispersed medium was realized. The controllable preparation platform was thus built. Over 40 kinds of transparent nanodispersions with high solid content (60 wt.%), high stability (over 1 year) and high transparency, including metal, inorganic, and organic substances were prepared. Furthermore, the scientific scale-up method for reactor based on “Scientific experiment + theoretical model + CFD simulation” was built to overcome the difficulty of scale-up, and the production lines of 100 and1000 ton nanodispersions were built, realizing the low cost industrial and stable production. Furthermore, based on nanodispersions, highly transparent nanocomposite film for energy-saving glass was developed. 7 million m²/year production line was built, and engineering applications were realized. In addition, a new idea of pseudohomogeneous catalytic degradation of waste PET plastics was presented, and 10,000-ton industrial demonstration was achieved. In the recent three years, as the corresponding author, I have published 36 SCI papers including AIChE J.、Angew. Chem. Int. Ed.、Chem. Eng. Sci.、Chem. Eng. J.、Small, etc. As the first inventor, I have achieved 13 granted Chinese patents. In addition, I have also obtained first prize of technical invention of China Petroleum and Chemical Industry Federation (The first finisher) and Youth Science and Technology Outstanding contribution Award of China Petroleum and Chemical Industry Federation.
