Abstract
Polymer nanocomposites (PNC) are of great interest owing to the many potential property enhancements possible via introducing different types of nanofillers in polymer matrices. In recent decades, increasing attention has being paid to PNCs due to their light weight, low cost, and ease of processability compared to metal alternatives and due to their novel capability to tune properties. Depending on the end-use application, certain PNCs properties are targeted and the PNC formulation and processing can be manipulated to achieve the desired properties.
In this PhD thesis, different PNC properties have been improved by employing different strategies: (1) modification of nanofillers, (2) synthesis of novel nanofillers, (3) implementation of hybrid fillers, and (4) amendment of PNC production methods. For nanofiller modification, chemical treatment of nanoclay, multiwall carbon nanotube (MWCNT) and graphene nanoribbon (GNR) were performed. For the second strategy, GNR was synthesized from parent MWCNT to benefit from higher surface area and interaction of the novel nanofillers with the polymer chains. The main objective of these two strategies is to improve the affinity and dispersion of nanofillers in the host polymer to enhance PNC properties. Utilizing a secondary filler to further enhance the desired properties was the third strategy and was accomplished via a hybrid filler PNC consisting of MWCNT and nanoclay. Finally, the fourth strategy was to develop optimized PNC production methods. The aim of the last two strategies was to obtain an improved morphology for the nanocomposite and it is well known that nanocomposite structure can be used to control the final PNC properties.
