Abstract
Blend films of poly(vinylidene fluoride)(PVDF) and poly(vinyl fluoride)(PVF) in different compostions were prepared by meltpressing and quenching in ice water after solution casting to obtain amorphous films. These blend films were extruded at two different temperature, 50℃ and 110℃. Draw ratio was increased with increase of fraction of PVF in blend composition and maximum draw ratio of blend film was 10 in composition of PVDF/PVF of 20/80 at 110℃. In investigation of birefringence, thermal and mechanical properties birefringence, Young''s modulus, tensile strength and % crystallinity were 4.55×10-2, 7.75 GPa, 140 MPa and 55% respectively, in case of draw ratio of 8 in blend film of PVDF/PVF 20/80 at 110℃.

Poly(vinylidene fluoride)(PVDF)와 poly(vinyl fluoride)(PVF)의 조성을 달리하여 블렌드 필름을 만들고 이것을 50℃와 110℃의 두가지 다른 온도에서 연신하였다. 연신비는 PVF의 성분이 증가할 수록 증가하였고, 블렌드필름의 최대 연신비는 110℃에서 PVDF/PVF의 조성비 20/80의 경우에 10을 얻었다. 연신한 필름을 이용하여 복굴절, 열적 및 역학적특성을 조사하여, 조성비 PVDF/PVF 20/80의 블렌드 필름의 연신온도 110℃에서 연신비 8의 경우 복굴절, 인장탄성률, 인장강도, 퍼센트 결정화도는 각각 4.55×10-2, 7.55 GPa, 140 MPa 및 55%이었다.
