A Review on CO<sub>2</sub>‐Based Polyureas and Polyurea Hybrids
Hui Li, Haiyang Cheng, Fengyu Zhao
Abstract
Abstract The utilization of CO 2 as a renewable and cheap carbon resource to produce fuels, chemicals and polymers has attracted more attention. This review will summarize the developments in the production of polymers like polyureas and polyurea hybrids with CO 2 as a monomer directly or indirectly. The influences of catalyst and the structure of diamine monomer on the molecular weight, thermal stability and mechanical properties of polyureas are discussed. In addition, the general properties and applications of functional CO 2 ‐based polyureas are also described. A few examples of CO 2 ‐based polyurea hybrids are also introduced. Finally, the future research priorities as well as the development trend of polyurea materials are depicted.
