采用原位聚合法,以过氧化二苯甲酰为引发剂,在形成水滑石的同时单体丙烯腈进入其层间并发生聚合反应,制备出聚丙烯腈/水滑石插层复合材料.用红外光谱、扫描电镜和X射线衍射对这种插层复合材料的结构进行了分析和表征,并对其燃烧性能和热性能进行了初步研究.结果表明:在水滑石片层之间通过原位聚合的方法生成了聚丙烯腈大分子,使水滑石层间距有一定程度的增大.聚丙烯腈/水滑石共混复合物的阻燃性能有一定提高,其极限氧指数(LOI)从18%提高到了21%;耐热性能得到一定程度改善.
採用原位聚閤法,以過氧化二苯甲酰為引髮劑,在形成水滑石的同時單體丙烯腈進入其層間併髮生聚閤反應,製備齣聚丙烯腈/水滑石插層複閤材料.用紅外光譜、掃描電鏡和X射線衍射對這種插層複閤材料的結構進行瞭分析和錶徵,併對其燃燒性能和熱性能進行瞭初步研究.結果錶明:在水滑石片層之間通過原位聚閤的方法生成瞭聚丙烯腈大分子,使水滑石層間距有一定程度的增大.聚丙烯腈/水滑石共混複閤物的阻燃性能有一定提高,其極限氧指數(LOI)從18%提高到瞭21%;耐熱性能得到一定程度改善.

Using in situ polymerization, the monomer acrylonitrile (AN) was intercalated and polymerized with benzoyl peroxide (BPO) as the initiator between the layer of layered double hydroxide (LDH). The structure of Polyacrylonitrile/layered double hydroxide (PAN/LDH) was characterized by Fourier transformed infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and X-ray powder diffraction (XRD). Both the flame retardant property and heat resistant were investigated. The results showed that PAN has been prepared between the layer of LDH by in situ polymerization and the interlay spacing of LDH has been expanded. The LOI of the blend was enhanced from 18% to 21%, which revealed that the flame retardant property has been improved. In addition, the heat resistant has been improved.
