Resource or Project Abstract

Polymer/clay nanocomposites are a relatively new class of materials with unique properties which are promising for applications in aeronautic, automotive, construction and healthcare fields, etc. The overall aim of this project was to further understand the impact of clay addition on polymers and polymer blends, which are often found in the recycled stock, and to investigate, with respect to the structure of clay, the thermal and mechanical properties of polymer/clay nanocomposites, with the emphasis placed on toughness. First, low-density and high-density nanocomposite cellular solids were synthesized, and their structure-property relationships were established. Next, high density polyethylene/clay micro and nano composites were prepared without or with the presence of an organic compatibiliser, and their thermal and mechanical properties were investigated. Then, polystyrene/clay composites were prepared using an organoclay pre-treated with different types of surfactants, and their structure and properties were studied. In order to facilitate exfoliation of clay in polymer matrices, a commercial organoclay was treated using a novel method. It was found that the treated organoclay improved the clay exfoliation in different polymer matrices. To help understand how polymer crystallinity and clay dispersion affect the final mechanical properties, nylon 6/clay nanocomposites with varying clay exfoliation degrees were melt-compounded and investigated in detail. Using the same materials, the toughness of the nanocomposites was studied via different testing methods and the fracture mechanisms were discussed intensively. The nanostructure for obtaining the optimum properties was also established. The effects of clay on pristine polystyrene/polypropylene blends with or without an organic compatibiliser were studied and the structure-property relationships for the polymer blends were developed. The effects of clay on recycled polystyrene and recycled polyethylene in the presence or absence of an organic compatibiliser were also investigated.
In conclusion, the addition of clay, upon appropriate treatments, to polymers and polymer blends can be beneficial for plastics recycling and beyond.

Lineage information about this project or dataset
The plastics industry in Ireland spans a wide range of sectors such as medical devices, electronics and packaging. Growth of plastics production and usage leads to the increasing amount of plastics wastes. Due to its distinct structure and properties, clay has potential in enhancing the properties of recycled plastics and thus facilitating plastics recycling. This project was set up to investigate such potential with the focus placed on toughness.
