文摘

Compatible p- and n-type melt mixed composites prepared with same base material. Polypropylene composites with singlewalled carbon nanotubes at 0.8 and 2.0 wt%. PEG addition during melt mixing switches p-type CNT composites into n-type. PEG increases electrical conductivity due to the better dispersion of fillers. TEG prototypes with output voltages of 21 mV (4 p/n) and 110 mV (49 p/n) @ ΔT = 70 K.
