| Abstract: |
| The graphene oxide/thermoplastic polyurethane（TPU） composites were prepared by solution blending and casting film method，and their structure and properties were investigated.The results showed that，graphene oxide was well dispersed in the TPU matrix.As the addition level（within 0～5 phr） of graphene oxide increased，the tensile strength of graphene oxide/TPU composites increased，and the elongation at break didn’t have any obvious decrease.Compared with carbon nanotube，graphite or carbon black，when the addition level of filler was 1 phr，the TPU composites filled with grapheme oxide showed better physical properties. |
