Abstract: |
The carbon nanotubes(CNTs)/polyurethane-imide(PUI) composite foam was prepared by pre-dispersion method and “one shot”method. The property of CNTs /PUI composite foam was investigated. The results show that theprevention performance of the composite foams material is very good,the oxygen index can reach 34. The composite foams have good open proe and acoustic performance, the open cell content reach 98%, the average acoustic coefficient(100-4000Hz,thickness 30mm)reach 0.59. In addition, the composite foams doped with CNTs show good microwave absorption properties.
