摘要: 聚甲基丙烯酸酯类(PMAs)是少数与聚偏氟乙烯(PVF2)热力学相容的聚合物。PVF2与聚甲基丙烯酸甲酯(PMMA)的共混体系已有不少研究,但多集中于两者的相容性,对其晶相研究较少。我们曾报道PMMA对高取向PVF2薄膜晶相结构的影响。本工作用富里叶变换红外光谱(FTIR)和透射电子显微镜(TEM)等方法研究了PMAs对高取向PVF2薄膜β相结晶的影响。

Abstract: Fourier transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM) have been used to study the effect of polymcthaerylates (PMAs),including PMMA,PEMA,PBMA,on the crystalline structure of highly oriented films of poly(vinylidene fluoride) (PVF2). The melt-drawn films of PVF2 consist of highly oriented lamellar structure. Addition of PMAs (in 20% by weight) in PVF2 resulted in the formation of shish-kabab structure and β-phase in order of PMMA>PEMA>PBMA. The results are discussed in terms of the hydrogen bonding between PVF2 and PMAs.
