| Abstract: |
| The nanokaolin/rubber (NR，SBR，BR or EPDM) composites were analyzed by TEM，XRD，IR and TGA，and their physical properties and thermal stability were investigated.The results showed that the nanokaolin/rubber composites had better resilience，tensile strength and thermal stability，but somewhat poorer tear strength and modulus when compared to the silica/rubber composite；and the excellent physical properties and thermal stability were mainly attributed to the nano-scale thickness and good dispersity of flaky kaolin particles，the tight bonding between flaky particles and rubber molecules in nano-size，as well as the separation and parallel arrangement to each other orientationally of flaky particles in rubber matrix. |
