Additive manufacturing (3D printing) is one of several new technological breakthroughs that are expected to lead the factories of the future, where conventional equipment will be replaced by smart, flexible and customized systems. In order for additive manufacturing technologies to truly evolve and attain their full potential the range of usable polymers needs to be significantly expanded and the properties of plastic materials need to be substantially improved. This can be achieved through the use of nanofillers which can lead to better materials with improved lifespan. However, like with any polymer nanocomposites the polymer-nanofiller interface and loading, dispersion, distribution and orientation of the nanofiller inside the polymer matrix are crucial factors that control the properties of the final material. Only by accounting for all the previously mentioned factors through structure-property relationships materials with superior properties can be manufactured.
Aims and Objectives:
The current project aims to develop new polymer nanocomposites and to evaluate their properties according to printing directionality. This will offer a better understanding of the role that the nanofillers play and provide a reliable view of the failure mechanism. Polymer nanocomposite materials will be developed using different polymer matrices and/or fillers at various loadings. The structure and properties of the developed materials will be evaluated and structure-property relationships will be investigated.
