Abstract: “Click” chemistry method was used to fabricate novel waterborne polyurethane (WPU)/montmorillonite
(MMT) composites based on alkyne-containing WPU and azide-modified montmorillonite. The morphology of these
composites was characterized by x-ray diffractometer, scanning electron microscope. The mechanical properties, thermal
stability, and flame resistance of the composites were investigated by tensile, thermogravimetry and cone calorimetric
experiments, etc. The experimental results show that the tensile strength, water resistance and flame retardancy of the
WPU/MMT composites have been reinforced efficiently owing to the linking of MMT by click reaction.
