PMIA纳米纤维改性复合耐高温滤料的制备及性能研究
Preparation and properties study of PMIA nanofiber modified composite high temperature resistant filter materials
摘要
Abstract
In order to develop high-temperature resistant and high-efficiency filter materials,aramid(PMIA)/PT-FE-PET composite filter materials were prepared by electrospinning technology using N-N-dimethylformamide/anhydrous lithium chloride(DMF/LiCl)as the solvent with the addition of nano-silica(SiO2)and carbon nano-tubes(CNTs)to form PMIA composite spinning solution,accompanied with PTFE-PET needle punched non-woven as the substrate.The mechanical properties,stiffness,air permeability,thermal stability and filtration per-formance of PMIA/PTFE-PET filter materials were explored.The results show that the PMIA/PTFE-PET com-posite filter materials exhibit good filtration performance,with the filtration efficiency of over 99.97％ for 0.3μm particles.It also has good thermal stability,with the initial decomposition temperature increasing from 382 ℃ to 415 ℃.Additionally,the breaking strength of the PMIA/PTFE-PET composite filter materials in-creased from 20.00 MPa to 27.45 MPa,showing good application prospects.关键词
