| Abstract: |
| The XNBR/graphene nanocomposite was prepared by hetero-coagulation，and the factors influencing the hetero-coagulation process were investigated.The results showed that the Zeta potential of XNBR latex and graphene in aqueous medium were negative，and the particles could not be coagulated in the pH value of 2～10 without the coagulant.It was found that CaCl2 and Al2（SO4）3 produced a preferable effect on the hetero-coagulation；when the agitation speed reached 300 r·min-1 or higher，small and uniform coagulated particles could be formed.The particle size of coagulated XNBR/graphene particles could be adjusted by the coagulating temperature. |
