摘 要:采用十八烷基二甲基叔胺(DMA)與對氯甲基苯乙烯(CMS)合成的季銨鹽(DMA-CMS)與α-磷酸鋯(α-ZrP)進(jìn)行陽(yáng)離子交換反應,合成了具有反應活性的有機修飾磷酸鋯(ZrP-DMA-CMS)。再利用本體聚合法,使該有機化處理的磷酸鋯與苯乙烯反應,合成了聚苯乙烯修飾的磷酸鋯P(St-ZrP-DMA-CMS)。運用FT-IR、TGA 、XRD對所制備的ZrP-DMA-CMS及P(St-ZrP-DMA-CMS)進(jìn)行了分析。XRD分析表明,DMA-CMS修飾的磷酸鋯層間距離由0.8 nm擴大為4.0 nm;聚苯乙烯修飾的磷酸鋯,其層間距則由4.0 nm進(jìn)一步擴大到4.4 nm。TGA分析表明,聚苯乙烯修飾的磷酸鋯P(St-ZrP-DMA-CMS)熱穩定性比α-ZrP提高了17%。 |

Abstract:The reactive organically-modified α-zirconium phosphate had been synthesized by ion exchange of cations in α-zirconium phosphate with a styryl quaternary ammonium salt,which had been obtained from the reaction of N,N-dimethyl octadecylamine with 4-chloromethyl styrene. Then,the polystyryl-modified α-zirconium phosphate had been prepared from the bulk polymerization of styrene with the reactive organically-modified α-ZrP. The reactive organically-modified α-zirconium phosphate(ZrP-DMA-CMS) and the polystyryl-modified α-zirconium phosphate[P(St-ZrP-DMA-CMS)] had been characterized by infrared spectra(IR),thermal gravimetric analysis(TGA)and X-ray diffraction(XRD). XRD results indicated that the layer d-spacing of ZrP-DMA-CMS had been enlarged from 0.8 nm to 4.0 nm,while the layer d-spacing of P(St-ZrP-DMA-CMS) had been enlarged from 4.0 nm to 4.4 nm. TGA analysis indicated the thermal stability of P(St-ZrP-DMA-CMS)was increased by 17% compared with α-ZrP. |
