Characterization of Cellulose and Chitin Thin Films and Their Interactions with Bio-based Polymers
As the two most abundant natural polymers on earth, cellulose and chitin have attracted increasing attention as a source of renewable energy and functional materials. Thin films of cellulose and chitin are useful for studying interactions of these materials with other natural and synthetic …

Investigating the endocrine disrupting potential and cytotoxic effects of packaging leachates and plasticisers
… This thesis assessed novel naturally produced bio-based polymers that are currently being explored as a potentially safer alternative to current synthetic plastics using in vitro bioassays. <br/><br/>The in vitro bioassays utilised in this thesis have shown to be valuable for assessing …

Abiotic and Biotic Polymer Degradation to Inform Sustainable Design
… is crucial to inform the sustainable design of polymers. This thesis is structured into three chapters, each addressing critical aspects of polymer degradation: In the first chapter, I develop and apply a sequential abiotic (photodegradation and hydrolysis) and biotic degradation test to a …

Designing High Performing Durable Bio-Based Coatings for Packaging Applications
… packaging applications using renewable biopolymers. These include cellulose, extracted from plants, and chitin, sourced from mushrooms and food waste like crustacean exoskeletons. These natural polymers can form strong, high-performance films but are limited by moisture sensitivity and …
