Poly(vunylidene fluoride)(PVDF)film was prepared using the N,N-dimethylformamide(DMF) solvent. By preparing, this film has the reverse pore which has thermal stable and hydrophobic. Common pore is a hole out the solvent. Nevertheless, Reverse film is made by crystallization though the process of film. Therefore, crystallized polymer chains associated with reverse pore in its vacancy. If this film is faced with heat shrink, reverse pore size is stable than other pores because PVDF film has thermal stability. These morphological features speculated from the SEM photographs |
