                 摘要:水滑石(LDH)是一类典型的阴离子型层状材料,具有优异的阻燃性和热稳定性,且低烟、低毒、环境
                 友好。将其与聚合物制备复合材料,可以显著提升聚合物的耐火能力,因而受到研究者的广泛关注。介绍了 LDH
                 的结构特点及其有机改性方法,包括离子交换法、煅烧还原法、一步法和溶剂剥离法。总结了常用于制备聚合
                 物/LDH 复合材料的方法,并简述了其优缺点。重点综述了影响聚合物/LDH 复合材料阻燃性的因素,主要包括
                 LDH 板层二价和三价阳离子、多金属阳离子的引入和改性剂等方面的影响;简述了其他阻燃材料配合 LDH 协
                 同阻燃的进展。最后,分析了阻燃型聚合物/LDH 复合材料的研究现状,就该材料在产业化推广、进一步提升高
                 效阻燃性能、明确阻燃机理等方面提出了观点。

                 Abstract:  Layered  double  hydroxide  (LDH)  is  a  typical  anionic  layered  material  with  excellent  flame
                 retardancy and thermal stability, low smoke, low toxicity and environmental friendliness. The preparation of
                 composites by combining LDH with polymers can significantly improve the fire resistance of polymers,
                 which  has  attracted  wide  attention  of  researchers.  This  paper  introduces  the  structural  characteristics,
                 organic modification methods of LDH including ion exchange method, calcination-reconstruction method,
                 one-step  method  and  solvent  exfoliation  method.  The  methods  commonly  used  in  the  preparation  of
                 polymer/LDH  composites  are  summarized  and  also  briefly  describe  their  advantages  and  disadvantages.
                 Furthermore, the factors affecting the flame retardancy of polymer/LDH composites are reviewed, including
                 the effects of LDH ply bivalent and trivalent cations, the introduction of polymetallic cations and modifiers.
                 A  brief  description  of  the  progress  of  other  flame  retardant  materials  in  combination  with  LDH  using
                 synergistic flame retardant. Finally, the author analyzes the research status of flame retardant polymer/LDH
                 composites.  The  viewpoints  of  industrialization  of  polymer/LDH  composites,  improvement  of  flame
                 retardant efficiency and clear flame retardant mechanism were put forward.
