Title : Non-destructive evaluation technique for assessing nanoparticle dispersion in composite materials


Extensive production of polymer composites reinforced by nanoparticles is hindered by the lack of non-destructive evaluation (NDE) methods capable of ensuring product quality and compliance with specifications. It is widely recognized that the dispersion level of nanoparticles in the polymer matrix significantly influences their enhancement capabilities more than any other parameter. In this study, an active infrared thermography NDT (IR-NDT) inspection, combined with pulsed phase thermography (PPT), was applied for the first time to nanocomposites to assess the dispersion level of nanoparticles. The PPT approach was tested on various nanocomposite samples with different levels of nanoparticle dispersion, including a nanocomposite with a very low nanofiller concentration (less than 0.05% by weight). The phasegrams obtained with this technique clearly reveal clusters or bundles of nanoparticles when present. Consequently, this new NDE approach can be employed to verify that the expected dispersion levels are maintained during the production process. The study also identifies the mechanisms underlying the effects of nanoparticle dispersion on the thermal response of polymer composites.
