Fabrication of nylon-6/POMs nanofibrous membranes and the degradation of mustard stimulant research

Abstract

Four types of nylon-6/POMs (H_3+nPMo_12−nV_nO₄₀·xH₂O and H₃PW₁₂O₄₀·xH₂O) composite nanofibrous membranes were fabricated by electrospinning the mixed solution of nylon-6 and POMs using HCOOH and water as solvents. The membranes were composed of randomly arranged nylon-6/POMs composite nanofibers with diameter range from 50 to 100 nm. Thermal gravimetric (TG) and differential scanning calorimetric (DSC) characterizations indicate high thermal stability of the membranes. The degradation ability of the composite fibrous membranes toward mustard (HD) was investigated. The results showed that the membrane has a good degradation performance toward HD with the degradation percentage as high as 41.55%. The degradation rates of HD by the four types of nanofibrous membranes are in the order of nylon-6/PMoV3 > nylon-6/PMoV2 > nylon-6/PW > nylon-6/PMoV1. The nanofibrous membrane simultaneously exhibit good filtration performance toward aerosol. The fabricated composite nanofibrous membranes show potential application in the in situ degradation of HD, and may be applied as a protecting cloth.
