Study on the Thermal Stability ofAmorphous Structure of Polyvinylidene Fluoride
摘要
Abstract
The thermal stability of the amorphous structure of polyvinylidene fluoride was investigated.Mid-dle infrared(MIR)spectroscopy studies were conducted including MIR spectroscopy(including one-dimensional MIR spectroscopy and second-derivative MIR spectroscopy)and temperature-dependent MIR spectroscopy(in-cluding one-dimensional temperature-dependent MIR spectroscopy and second-derivative temperature-depend-ent MIR spectroscopy).The experiments revealed that the amorphous structure of polyvinylidene fluoride exhibi-ted three characteristic peaks including v-2-amorphous structure,v-3-amorphous structure and v-4-amorphous structure.As the measure-ment temperature increased,variations were observed in both the absorption wave numbers and intensities of the peaks corresponding to the amorphous structure of polyvinylidene fluoride.Notably,the thermal stability of the a-morphous structure corresponding to v-3-amorphous structure was weaker than that of the amorphous structure correspond-ing to the v-2-amorphous structure.MIR spectroscopy can facilitate rapid research on the thermal stability of the amor-phous structure of polyvinylidene fluoride.关键词
