摘要: Abstract As electrically conductive polymer composites, glycerol plasticized-starch (GPS)/carbon black (CB) membranes are respectively prepared by melt extrusion and microwave radiation. Scanning electron microscopy shows that the electrical conductance network of CB is formed in GPS/CB membranes, radiation (GPS/CB-MR). However, agglomerates particles isolated (GPS/CB-ME). Fourier Transform Infrared (FTIR) spectroscopy reveals GPS matrix can form interaction membranes. According to Nicholais–Narkis models, reinforcing effect more obvious GPS/CB-MR than GPS/CB-ME exhibit a low percolation threshold 2.398 vol% loading conductivity membrane containing 4.236 reaches 7.08 S/cm, while very 10 −8 S/cm at high content. In addition, have better water vapor barrier
