| 제목 | Investigation of the coalescence phase between mesophase spheres during mesophase formation |
| 초록 | The molecular weight of the pitch increases with the synthesis conditions (temperature, time, pressure). Between the components having a molecular weight more than 2,500 amu laminated by Van der Waals force, this region is called mesophase. In general, mesophase forms a bulk mesophase through the formation and growth of mesogen and coalescence between mesophase spheres. Therefore, sufficient reaction conditions for mesogen formation and proper viscosity for coalescence between mesophase spheres are important factors for forming bulk mesophase. In this paper, the mechanism of coalescence between mesophase spheres during the bulk mesophase formation is discussed. The following two mechanisms were proposed as the coalescing mechanism of mesophase spheres. 1) Polymerization of low boiling point components in pitch, 2) Reduction of isotropic area by volatilization. To visually confirm this process, mesophase pitch and isotropic pitch were mixed at a mass ratio of 8:2, 6:4, 4:6, and 2:8. |
