摘要：The average concentrations of negative air ions (Cion-) emitted from tourmaline (T), bamboo charcoal (B) particles, and tourmaline/bamboo charcoal (T/B) compounds containing polypropylene (PP) and ethylene propylene diene terpolymer/polypropylene (EPDM/PP) composite specimens under varying testing conditions were investigated in this study. The Cion- values emitted from T or B filled PP and EPDM/PP composite specimens reached a maximum value as their T or B contents approached the 5 and 3 wt % optimum values, respectively. In contrast, the Cion- values of T/B compounds filled PP and EPDM/PP composite specimens were significantly higher than their theoretical Cion- values estimated using the simple mixing rule, and reached a maximum value as the weight ratio of T to B reaches an optimum value. At this optimum T/B weight ratio, the Cion- values of T/B compounds filled PP and EPDM/PP composite specimens reached another maximum as their total compound loadings reached the optimum loading of 6 and 4 wt %, respectively. The Cion- values of the PP/T/B and EPDM/PP/T/B specimens increased significantly as they were tested under dynamic mode or by increasing the testing temperatures. The T and/or T/B powders filled PP and EPDM/PP specimens exhibited significantly higher tensile strength (f) and elongation at break (f) values than did the B filled PP and EPDM/PP specimens with the same filler loadings, respectively. Energy dispersive X-rays, particle size, and SEM morphology analysis of the filler particles present in the T, B, and T/B filled composite specimens were performed to understand these interesting negative air ion and tensile properties.
