      Nanotubes and Ammonium Polyphosphate in Unsaturated Polyester Resin.

AB  - Imogolite nanotubes (INTs) were synthesized from tetraethoxysilane, aluminum 
      nitrate nonahydrate, and ammonia solution by the method of Arancibia-Miranda, and 
      their dispersion was modified by 1-butyl-3-methylimidazolium hexafluorophosphate 
      ([BMIM]PF(6)) to obtain ionic liquid (IL)-functionalized INTs (INTs-PF(6)-ILs). 
      Then, the flame retardant INTs-PF(6)-ILs was complexed with ammonium 
      polyphosphate (APP) and applied to unsaturated polyester resin (UPR). The 
      limiting oxygen index value and the UL-94 level of the UPR/APP/INTs-PF(6)-ILs 
      composites reached 28 and V-0, respectively. The residual carbon of the 
      composites in thermogravimetric analysis increased by 19.47%, compared with that 
      of pure UPR. The cone calorimeter test result showed that the peak of heat 
      release rate and total heat rate values of the UPR/APP/INTs-PF(6)-ILs composites 
      were lowered by 41 and 34% than those of the pure UPR, respectively. The effect 
      of heat combustion and the maximum mass loss rate of UPR/APP/INTs-PF(6)-ILs 
      composites were also greatly decreased. There were no holes or folds observed on 
      the surface of the UPR/APP/INTs-PF(6)-ILs composites' residual carbon in scanning 
      electron microscopy images. The intact residual carbon could have effectively 
      insulated the heat and oxygen to improve the flame retardant performance.
