| Summary: | This paper presents the study of rheological and thermal behaviour of high impact
polystyrene/multiwall carbon nanotubes (HIPS/MWCNTs) nanocomposite. The nanocomposite was
prepared via melt mixing method. The influence of different loadings of MWCNTs on the HIPS
viscosity and other rheological characteristics were analyzed experimentally. Other rheological
characteristics were studied using dynamic analysis of viscosity through rotational rehometer. Glass
transition temperature (Tg) were also investigated using non-isothermal differential scanning
calorimeter analysis. The viscosity was found to be directly proportional to MWCNTs’ loading, up
to five times the value of pure HIPS at loading level of 7.5wt% of MWCNTs. The MWCNTs
loading demonstrated a marginal effect (1-2%) on the Tg. |
