| 摘 要： | 对聚偏氟乙烯(PVDF)、PVP、各种比例的PVDF/PVP共混物,以及通过共辐射接枝得到的多种接枝率的PVDF-g-PVP接枝共聚物进行了红外光谱测定.与称重法得到的结果相比较,发现利用红外光谱可以较好地得到样品中PVP含量的定量结果.研究发现,在共辐照条件下,吸收剂量低于26 kGy的辐照对PVDF的红外光谱基本无...

| Abstract: | PVDF,PVP,PVDF/PVP with different blend ratios and PVDF-g-PVP graft copolymer with different grafting degree were characterized by Fourier transform infrared(FTIR).As indicated by the corresponding relationship of gravimetric analysis,FTIR is feasible for the quantitative determination of PVP in the samples.It is found that when the absorbed dose was below 26 kGy,the irradiation had little influence on the spectra of PVDF.But compared to the blend with the same content of PVP,the intensity of the special car... |
