摘要
采用共沉淀法合成了对甲基苯磺酸有机插层改性的镁铝水滑石,用XRD、FTIR、TG-DSC等技术表征产物特征。研究表明,合成的对甲基苯磺酸插层LDH物相纯净、结晶度高,层间无硝酸根,而且2∶1型有更好的晶形;2∶1型对甲基苯磺酸插层LDH在450~500℃层状结构逐渐被破坏,而3∶1型在400~460℃0层状结构被破坏。因此2∶1型对甲基苯磺酸插层LDH更稳定,为进一步研究聚合物基水滑石复合材料奠定了基础。
The p-Toluenesulfonate intercalation layered double hydrotalcites was synthesized by using co-precipitation method.The products were charactered with XRD、FT-IR、TG and DSC.The results indicated that LDH-PTS were pure and 2：1 type LDH-PTS have better crystallinity than 3：1 type LDH-PTS.And layered structure of 2：1 type LDH-PTS gradually destroyed between 450~500oC,but layered structure of 3：1 type LDH-PTS gradually destroyed between 400~460oC.The successful preparation of LDH-PTS implied the polymer/LDH composites had the wonderful research prospect.
