Abstract

In the present study, a gradient structure in a blend composition was developed without phase separation under a temperature gradient. A miscible polymer blend composed of polymethylmethacrylate (PMMA) and polyvinylidene difluoride (PVDF) was used. The viscosity of the PVDF was much lower than that of the PMMA in the molten state. After exposure to the temperature gradient, the PVDF content was greatest at the high-temperature side and lowest at the low-temperature side. Because the high-temperature side contained more PVDF, its surface free energy was lower than that on the low-temperature side.
