The laboratory was established in 1996 intended to explore new chemistries in transferring inert C-H bonds to reactive or polar groups. With the continuous efforts of more than 20 years, we have created a number of new chemistries and developed a number of novel technologies in polymer surface modification, functionaliztion of polyolefins, and the new technologies of controlled radical polymerizations. Some of the new technologies have been licensed to industrial companies. The achievements, to name a few, including:


Photo-assisted Surface C-H Transformation Chemistry and Related Technology. Coined a concept of “surface confined reaction” and developed a series reaction, for examples, the surface living radical grafting polymerization in organic polymer substrates, confined photo-catalytic oxidation, and oxygen- centered phenoxy radical coupling. The surface living grafting polymerizations have been successfully applied not only to grafting polymer brushes but to fabricate 3-D micro-architectures on the surface of flat/particulateorganic substrates. In addition, the surface grafting polymerization has also been applied to develop new high performance polyolefin grafting polymers. The last to reactions are robust tools in introducing monolayer reactive and polar groups, such as hydroxyl, carboxyl, amino, epoxy, thiol and glycosyl onto the organic substrates. These attractive chemistries and technology have been published as invited reviews (Chem. Rev., 2013, 113, 5547-94 and Prog. Polym. Sci., 2009, 34, 156-93) and feature article (Polymer, 2011, 52, 4159-73).


Self-stablized Precipitation Polymerization.  With the controlled the difference of the solubility parameters of the solvent and polymer, a new heterogeneous polymerization process differentiated from the conventional emulsion, suspension and dispersion polymerization was observed and we named as “Self-stablized Precipitation Polymerization”. After the nucleation stage, both the monomer conversions and particle sizes increased steadily, while the coefficient of variation of the particle size decreased. The almost linear relationship between the Dn3 and the weight of produced polymer was observed.


In the past decade, the scope of our lab is extended to the living radical polymerization, controlled coordination polymerization of vinyl and acetenyl monomers. With these novel polymerization chemistry and process as tools, various functional polymers, for example, high performance polyolefins, helix polymer, and polyacrylamide of tolerance to high temperature and salinity have been developed.    There are some promising areas, such as cycloketyl radical mediated living polymerization, molecular net-cloth grafted on polymeric substrates and its application for cell and enzyme immobilization, diseases detecting and dianogosis chips, etc.
