| Summary: | Continuous usage of bioreactor causes early degradation of most bioreactor liner materials due to the effects of various chemicals,
consequently resulting in contamination in the bioprocess. Performance of PP-ternary nanocomposite (PPTN) for its potential
application in the fabrication of bioreactor liner material was investigated in this study. The chemical resistance of the
composite samples obtained was tested by exposing them to chemicals such as acid, alkaline, water and bacterial solutions,
according to ASTM 543-06, and their effects on the composite samples were carefully observed. Specifically, the investigation
focused on the changes in the physico-mechanical properties of PPTN following long term of exposure to these chemicals. The
results show slight increase in the weight and dimensions of samples in the first few days, followed by constant reading for the
period of 4 weeks. The performance in terms of physical properties was in the range of PPTN with 0.61% MWCNT > PPTN
0.45% > PPTN 0.17%. The maximum percentage change in tensile properties, observed in this study, was approximately 10%
against PPTN (0.17%), which indicates stable mechanical properties of the composite and invariably suggests that the nanocomposites
could serve as a better alternative for bioreactor liner fabrication |
