【Abstract】 The reaction of the isocyanate group with water generates amine and CO2 provides a convenient and efficient means for preparing porous polyurea material. The FTIR confirms the synthesis of intended polyurea polymer and the location of hydrogen bonding in the copolymers. The porous polyurea material has interconnected skeletal network structures, which are composed of fiber-like clusters. The TGA demonstrates that the porous polyurea material is stable at temperature lower than 280℃, and it has strong hydrophobic and oleophilic properties.更多还原
