| Abstract: | PVDF thin films were prepared by the tape casting method and the process of spherocrystal growth was observed by polarizing microscope.The influences of the cooling velocity and the crystalline method to the grain morphosis in the construction of PVDF crystallizing were analysised.The test result indicated that the technology of isothermal fast cooling was better to obtain the more homogeneous crystallization of PVDF membrane. |
