| 中文摘要 | the block copolymer or graft copolymer formed by the in situ interface chemical reaction can be used as effective compatibilizer in the process of polymer blending materials. the structural evolution of an a/b/s ternary mixture is investigated in which the a and b components can undergo a reversible chemical reaction to form s which may act as a compatibilizer. the free-energy lattice boltzmann simulation method (lbm) was adopted in this study. in this theoretical frame work, the chemical reaction terms can be incorporated into the second order parameter drift-diffusion equation via a specific forcing term. using this method, the effect of chemical reaction rate, shear velocity and oscillatory frequency on the structure evolution was simulated. we provided the space distribution and the time evolution of compatibilizer s. the simulative results denoted that the component s can reduce the size of the dispersed phase greatly. increasing the chemical reaction rate too much can lead the compatibilizer to form independent phase zone and not distribute in the interface. the high shear velocity and low oscillatory frequency got the phase structure to be stretched especially closed to the shear boundary. they are the crucial factors determining the structure evolution of blend mixture under shear flow. finally, these results provide guidelines for controlling the morphology of this complex mixture. |
