| Abstract: | The effect of three different fillers on the structure and properties of polypropylene blends were investigated. The β nucleating agent can successfully induce β crystal in modified iPP blends and the turning point of the properties appears at the content of 0.5 wt%. For the properties of carbon nanotube modified iPP blends, there is no turning point because of its dominant α-crystalline morphology. The β NA supported carbon nanotube shows better induction ability than the single β NA or single carbon nanotube, there is also a turning point existing at the content of 0.5 wt%. |
