This article summarized the preparation methods of polyurethane/nano-composite materials in recent years. It mainly introduced the blending method
in situ polymerization method
intercalation polymerization method
sol-gel method
etc
which were commonly used in the preparation of polyurethane nano-materials modified. Elaborated a number of methods of surface modification
which used for nano-materials. Finally
the researcht rends of the polyurethane/nano-composite materials were pointed out: The dispersion of nanoparticles still need further study and prefection; For the rarely reported nano-diamond
nano-SiC and other new super-hard nano-materials need more researches and applications; Polyurethane/nano-composite materials'new preparation needs further/ deeply study; Its Industrial applications wait for further develop.
