The project aim is to introduce the first optically readable sequence-defined polymers based on fluorophore excimers, whose information content can be read as simply as conventional barcodes. These macromolecular barcodes, embedded in solid polymer matrices, will overcome the current limitations of reading information from synthetic macromolecules. An interdisciplinary effort will fuse chemistry, law, and criminology to develop the technology in ways that are expected to address illicit plastic waste trafficking – ending the anonymity of polymer waste by creating a regulatory and criminological paradigm for tracing plastic waste to hold actors in the value chain responsible.Read moreRead less

This project will break new ground in light-induced step-growth precipitation polymerisation techniques for polymer particle formation that do not require any initiator, surfactants, additives or heating, thus constituting an environmentally friendly process. The project will establish the underpinning photochemical particle formation processes and establish a broad monomer base for the production of particles with a wide property profile, including particles with tailored surface properties and the ability to degrade upon a defined trigger signal. Scaling the particles' synthesis, including using Australian sunlight, will enable multi-gram production allowing real-world applications.Read moreRead less
Sustainable Reversible Polymerisation. This project aims to address the problem of the current lack of efficient chemical recyclability of polymers. For the majority of polymers, no methods exist so far that are scalable and economic at the same time. To reach this aim, we will utilise a mixture of clever chemical concepts with continuous flow engineering.

This project aims to address the problem of the current lack of efficient chemical recyclability of polymers. For the majority of polymers, no methods exist so far that are scalable and economic at the same time. To reach this aim, we will utilise a mixture of clever chemical concepts with continuous flow engineering. This project expects to generate new knowledge in the area of depolymerisation and chemical recycling methods. The expected outcome of this project is a scalable process and its practical demonstration for full chemical recycling of various polymers used in everyday applications. This will provide a benefit to society as it allows to tackle plastic pollution problems, and creates avenues to green methods in plastic recycling.

An in-built depolymerisation solution for polyethylene waste. This project aims to design enzymes that can be embedded into polyethylene, and later activated by the elevated temperatures of a compost heap, to depolymerise the plastic to small molecules. There are no good options available for the controlled decomposition of polyethylene waste at present, and instead researchers have focussed on solutions that rely on modifications to the underlying chemistry of the backbone and or collection to ....An in-built depolymerisation solution for polyethylene waste. This project aims to design enzymes that can be embedded into polyethylene, and later activated by the elevated temperatures of a compost heap, to depolymerise the plastic to small molecules. There are no good options available for the controlled decomposition of polyethylene waste at present, and instead researchers have focussed on solutions that rely on modifications to the underlying chemistry of the backbone and or collection to a central facility. Our approach would result in an in-built decomposition that does not require collection and recycling in a central facility. Since it is based on a depolymerisation mechanism it does not result in the production of harmful, partially disintegrated microplastics.Read moreRead less

Developing smarter nanoparticles is critical for maximising the potential of biological therapeutics such as nucleic acids. Currently, the efficiency of nanoparticle delivery remains low due to the inability of carriers to migrate different biological regions. The aim of this project is to develop responsive polymer nanoparticles that can more effectively migrate cell barriers by a two-staged release based on the combination of different self-immolative polymers. This project will allow the development of design rules for understanding how nanoparticle structure can be optimised to improve nucleic acid delivery. This work will have important benefits such as developing new nanotechnology industry and skilled graduates for Australia.

Hybrid inorganic-organic materials have important applications in energy, environmental and health technologies. Sequential infiltration synthesis (SIS) of polymers is a recently introduced approach to preparing such hybrid structures. Advancement in the field is however hampered by lack of fundamental understanding of the mechanisms of interactions of SIS molecules with polymers, and the narrow range of polymers studied so far.

Smart materials for atmospheric water management and water harvesting. Fresh water is a scarce resource in many parts of the globe but uncomfortably over-supplied in other regions. Dehumidifying machines, such as air conditioners, are extensively used in humid climates to enhance human comfort, but with great energy costs. Likewise, the production of potable water in remote dry regions is energy intensive.

Fresh water is a scarce resource in many parts of the globe but uncomfortably over-supplied in other regions. Dehumidifying machines, such as air conditioners, are extensively used in humid climates to enhance human comfort, but with great energy costs. Likewise, the production of potable water in remote dry regions is energy intensive. We propose novel hyper-absorbent desiccating polymers combined into sorption-powered engines inspired by nastic movements in plants to develop extremely efficient dehumidifiers and water harvesting machines. These polymer actuators can help address the auto-acceleration of climate change caused by the increasing use of air conditioners and provide cheap, clean water for remote communities.Read moreRead less
