摘要 | It remains very challenging to create porous materials with both good thermal insulation and flame retardancy for construction of energy-saving buildings. Herein, we report the first example of ionic liquid (IL)-based monolithic porous polymers as efficient flame retardant with good thermal insulation, which was synthesized by polymerization of vinyl tetrafluoroborate ionic liquid monomers with polydivinylbenzene (PDVB) as a crosslinker through a facile solvothermal synthesis followed by freeze drying (named as PDVB-BF(4)ILs). The PDVB-BF(4)ILs is mainly composed of mesopores with a pore sizes ranging from 8.8 to 20.3 nm. The PDVB-BF(4)ILs has a decomposition temperature of higher than 320 degrees C. The PDVB-BF(4)ILs show high thermal insulation with a low thermal conductivity (0.019W m(-1) k(-1)) in air. Also, the PDVB-BF(4)ILs possesses excellent flame retardancy with a low peak heat released rate (139.3W g(-1)). Compared with porous PDVB, the pHRR of PDVB-BF(4)ILs was reduced by approximately 75%. Torch burn test implies that the PDVB-BF(4)ILs shows self-extinguishing behavior without generation of any melt dripping, indicating an excellent flame retardancy. Taking advantages of simple fabrication process, easily to be scaled-up, excellent thermal insulation and flame retardancy, such IL-based monolithic porous polymers may have great potential for real applications. |
